1. Understand your audience
Before you write a single subject line, it’s crucial to understand who you're writing for. Each prospect is different, and so are their needs and challenges.
The most effective email subject lines for sales address a specific pain point or offer a solution to something your prospect is actively dealing with.
- For example, if you're targeting small businesses, a subject line like “Grow your business with these proven marketing strategies” speaks directly to their goal of growth.
- If you're reaching out to a prospect in the healthcare industry, “Improve patient care with our tech” could appeal to their primary focus.
By tapping into the mindset of your audience, you ensure your sales email subject lines resonate with what they care about most.
2. Keep it short and clear
People are busy and often skim through their inboxes quickly, so your subject line should be short enough to be read at a glance.
A subject line that’s too long or unclear can be ignored or cut off entirely. Keep it concise and direct.
- Aim for under 50 characters to ensure the subject line isn’t truncated, especially on mobile devices where space is limited.
- A good email subject line is one that immediately conveys what the email is about and why it matters without the need for further explanation.
For example, instead of “Here’s a great solution to increase your sales in just a few easy steps,” a shorter version like “Boost your sales with these proven methods” is more effective.
3. Make it compelling
A well-crafted subject line is not just informative; it’s designed to spark curiosity or action. Compelling subject lines use strong language that inspires urgency or highlights value.
- Action-oriented language, such as “Get started today,” “Don’t miss out,” or “Claim your spot now,” creates a sense of urgency and encourages the recipient to open the email immediately.
- Highlighting value in the subject line is equally important. Words like “exclusive offer,” “free trial,” or “limited-time discount” clearly indicate to the recipient what they stand to gain by opening the email.
For example, “Exclusive offer for new customers” is more compelling than simply “New customer discount.”
4. Personalize the subject line
Personalization is a powerful tool in sales emails. A personalized email subject line draws attention by making the recipient feel that the email was meant specifically for them.
Using the recipient's name or the company name in the subject line increases relevance and makes the email feel more personalized.
- Personalization doesn’t always mean using just their name. If you’re reaching out to a company, you can use the company’s name to create a connection. For instance, “John, here’s how [Company Name] can increase efficiency.”
- You can also personalize by referencing previous interactions or specific challenges the prospect has shared.
Personalization can significantly increase open rates because it makes the subject line feel more direct and relevant to the individual receiving it.
5. Create curiosity or intrigue
The most effective subject lines are often those that make the reader curious enough to open the email.
This can be achieved by implying that something is interesting, valuable, or useful inside the email without revealing everything in the subject line.
- Phrases like “You won’t believe what we’ve got for you” or “Unlock a surprise inside” pique curiosity and motivate recipients to see what the email contains.
- You can also use a question to trigger intrigue, such as “Want to know how to save time and money?” or “Are you ready to scale your business?” This approach invites recipients to learn more by opening the email.
Effective curiosity-driven subject lines strike the perfect balance between intrigue and clarity, prompting recipients to learn more.
6. Test and optimize
Not every subject line works equally well for every audience. What resonates with one segment might not work with another, which is why testing is essential.
A/B testing subject lines allows you to compare different versions and see which one performs better.
- You can experiment with different approaches, such as short vs. long subject lines, formal vs. informal tone, or personalized vs. generic phrasing.
- Once you find what works best for your audience, you can refine your approach for future emails.
For example, you might discover that your audience responds better to subject lines that include action verbs or questions rather than just straightforward statements.
By regularly testing and optimizing your subject lines, you ensure that your emails are as effective as possible in driving engagement and conversions.

Common mistakes to avoid in sales email subject lines
Crafting an effective sales email subject line is crucial for success, but many marketers and sales professionals make some common mistakes that can negatively impact their email engagement rates.
By being aware of these errors, you can improve your chances of getting your emails opened and read. Here are some common mistakes to avoid:
1. Being too vague
A subject line that’s too vague doesn’t give the recipient enough reason to open the email. If your subject line doesn’t indicate the value or purpose of the email, your prospect is likely to ignore it.
For example, subject lines like “Important information” or “You need to see this” are generic and don't offer enough detail to spark curiosity.
Instead, be specific and let your recipient know why the email is worth their attention.
2. Using excessive punctuation or all caps
While it’s essential to stand out, using excessive punctuation or writing in all caps can make your email look unprofessional or spammy.
Subject lines like “SALE!!! HUGE DISCOUNT!!!!” or “GET YOUR FREE GIFT NOW!!!” can be off-putting and often trigger spam filters, preventing your email from even reaching the inbox.
Keep your subject lines clean and professional, and avoid overusing symbols like exclamation marks or question marks.
3. Making it too long
Long subject lines get cut off, especially on mobile devices, where space is limited. If the recipient can’t see the whole subject line, they may not understand the value of your email or may skip over it.
Ideally, keep your subject lines under 50 characters to ensure they display properly in the inbox and make an immediate impact.
4. Being overly salesy or pushy
Subject lines that are too aggressive or overtly sales-focused can turn prospects off. Phrases like “Buy now!” or “Limited time offer!” can sound like brutal sales tactics and may cause recipients to hesitate.
While urgency can be compelling, it’s essential to strike a balance. Focus on building a relationship with your prospects by offering value and providing helpful information rather than just pushing for a sale in the subject line.

5. Failing to personalize
Personalization can significantly enhance the effectiveness of your subject lines, but many marketers overlook this opportunity.
A generic, impersonal subject line is less likely to capture attention. By adding a prospect’s name or referencing their company, you make the email feel more tailored to them.
Personalized subject lines have been shown to increase open rates because they feel more relevant and engaging.
6. Being misleading
Misleading subject lines are a surefire way to lose trust and damage your reputation. If your subject line promises something that isn’t delivered in the email, your recipients will feel deceived, and they may unsubscribe or mark your emails as spam.
Always ensure your subject line accurately reflects the content inside the email to maintain credibility and trust with your audience.
7. Ignoring mobile optimization
With the rise of mobile email usage, it’s essential to ensure your subject lines are optimized for smaller screens. If your subject line is too long or unclear, it may be cut off, making it less effective.
Always check how your subject line appears on mobile devices and ensure it’s concise and clear enough to grab attention on the go.
8. Using too many generic phrases
Phrases like “Important update” or “Check this out” can come across as overused and uninteresting. While these terms might be attention-grabbing initially, they fail to stand out in a crowded inbox.
Instead, try to come up with unique and creative subject lines that reflect the value of your email while keeping it fresh and relevant.
9. Overcomplicating the language
Complex or overly technical language can confuse your audience and make your subject line less appealing. Keep things simple and easy to understand.
Your goal is to quickly communicate what the email is about and why it’s worth opening, not to make it hard for the recipient to decode your message.
10. Not testing subject lines
Finally, not testing your subject lines is a common mistake that can hold back your email marketing efforts. Without testing, it’s hard to know what resonates with your audience.
Running A/B tests on different subject lines can help you determine which ones drive the best engagement. Small changes, such as tweaking the wording or adjusting the tone, can have a significant impact on your open rates.
Do’s and Don’ts for writing sales email subject lines
Writing effective sales email subject lines is crucial for getting your emails opened and engaging your audience. To help you craft subject lines that drive results, here are some key do’s and don’ts to follow:
Do’s
- Do keep it concise and clear
A great email subject line should be clear and concise, getting straight to the point. Keeping it brief ensures the recipient knows what the email is about without getting lost in a long message, especially when reading on mobile devices. - Do personalize your subject lines
Personalization can significantly increase your open rates. Adding a recipient's name or mentioning their company name makes the email feel more relevant and increases the chances of it being opened. For example, "John, here's a quick tip for [Company Name]." - Do create curiosity
Spark curiosity by hinting at something valuable or interesting inside the email. Use subject lines that leave the reader wanting more, such as “You won’t believe what we can do for you” or “Here’s a simple solution to your problem.” - Do use action-oriented language
Strong, action-oriented language encourages the reader to take the next step. Phrases like “Claim your discount now” or “Start improving today” create a sense of urgency and encourage the recipient to open the email. - Do test your subject lines
Always test subject lines to see what resonates best with your audience. Run A/B tests on different versions to determine which subject lines generate the highest engagement. - Do use urgency when appropriate
If it fits the context, creating urgency can prompt recipients to open your email immediately. Words like “limited time” or “act fast” can make the email feel time-sensitive and encourage immediate action.
Don'ts
1. Don't be vague
Avoid vague subject lines that don’t give enough information about what’s inside the email. Good email subject lines for sales communicate the value of opening the email.
For instance, “Check out this new product” is much less effective than “Introducing our new product, designed to save you time.”
2. Don’t use excessive punctuation or all caps
Overusing exclamation points or writing in all caps can make your email appear unprofessional and may trigger spam filters.
Keep your subject lines clean, straightforward, and easy to read.
3. Don’t make it too long
Subject lines that are too long often get cut off, especially in mobile inboxes.
Aim for subject lines of 50 characters or less to ensure the whole message is visible and easily understood.
4. Don’t be overly salesy
While sales email subject lines should be persuasive, avoid being too pushy. Words like “Buy now!” or “Exclusive offer” can sound too aggressive and may drive people away.
Instead, focus on creating value and offering something helpful to your audience.
5. Don’t mislead your recipients
Misleading subject lines can quickly damage trust. Always ensure that the subject line accurately reflects the content of the email.
If your subject line promises a benefit, make sure it’s delivered in the body of the email.
6. Don’t use generic phrases
Generic subject lines like “Important update” or “Check this out” are overused and don’t stand out.
To make your subject lines more effective, be creative and unique, ensuring they immediately grab the recipient’s attention.

The best keywords to use in sales email subject lines
Using the right sales email subject lines and keywords is crucial for capturing attention and driving engagement.
Here are some types of keywords you can use to enhance your subject lines, along with brief explanations:
1. Action-oriented keywords
These keywords encourage immediate action and can help prompt the recipient to open your email without delay.
These types of subject lines are effective for re-engaging prospects who haven’t responded to previous emails.
2. Benefit-driven keywords
Benefit-focused keywords communicate the value that recipients will gain by opening the email. Highlighting the clear value proposition behind your offer drives action.
For example, offering solutions to a prospect's desire or improving their business can attract attention.
- Examples: “Boost your sales,” “Increase efficiency,” “Save time,” “Maximize profits”
3. Urgency-based keywords
Urgency keywords push recipients to act fast before they miss out.
This type of subject line is often used for time-sensitive offers that align with the sales cycle or promotions that are about to expire. Using phrases like “last chance” or “act now” can create a sense of urgency.
4. Social proof keywords
Social proof, like “recommended by” or “trusted by others,” builds credibility and reassures the recipient that your offer is reliable.
This can be especially helpful when you want to establish a competitive advantage or leverage success stories.
5. Personalization keywords
Personalized subject lines make the recipient feel that the message is specifically relevant to them.
Addressing the prospect's time and showing that you understand their needs helps make the email feel more tailored.
A meeting request subject line can also be personalized for more effective follow-ups.
- Examples: “For [Company Name],” “Hi [Name],” “Just for you,” “[Prospect’s Name], we have something for you”
6. Free offer keywords
Offering something free can spark interest and increase open rates. When you offer a free idea or consultation, you provide immediate value, making the email even more appealing.
Just ensure your email subject line doesn’t come across as too “salesy” to avoid being flagged as spam.
The role of emojis in sales email subject lines
Emojis have become a popular addition to sales email subject lines due to their ability to catch attention and convey emotions in a visually engaging way.
When used correctly, emojis can make your subject line stand out in a crowded inbox and add a layer of personality to your message.
However, it's essential to use emojis strategically to ensure that they enhance your subject line rather than detract from it.
Benefits of using emojis
1. Increased visibility
Emojis can help your subject line stand out among the sea of text-based emails in a recipient’s inbox. By adding visual elements, your email is more likely to catch the prospect’s attention, especially in mobile inboxes where space is limited.
2. Humanizes the message
Emojis can make your sales email feel more personal and less formal. This can help establish a friendly connection with the recipient, which is particularly important when you’re trying to build rapport as a sales rep.
3. Conveys emotion quickly
Emojis help convey emotions or tone, providing clarity in a subject line. For example, using a smiley face 😊 or a thumbs-up 👍 can give your email a positive, upbeat feel, which could be perfect for offering an exclusive deal or celebrating an achievement.
4. Saves space
Emojis can replace words, making your subject line more concise. This can help you create a great subject line without exceeding the character limit, especially on mobile devices where space is crucial.
5. Increases engagement
Catchy email subject lines with emojis can lead to higher open rates, as they immediately grab attention. A well-chosen emoji can also give the recipient a sense of curiosity or excitement, prompting them to open the email to see what’s inside.
Considerations
1. Don’t overdo it
Using too many emojis can make your subject line look cluttered or spammy. Maintain focus on clarity and value while incorporating a few carefully selected emojis to enhance your message.
2. Match the tone
Emojis should align with the tone of your email. If you're addressing a serious prospect's pain points, avoid emojis that could undermine the professionalism of your message. Conversely, if your email offers a free idea or valuable insights, emojis can enhance the friendly, approachable tone.
3. Know your audience
Consider the preferences of your prospect’s company and your target demographic. Some industries or professionals may appreciate a more formal approach, while others may respond better to the fun and engaging touch of emojis.
4. Stay on brand
Ensure that the emojis you use are consistent with your overall brand voice. Using emojis that don't align with your approach can confuse recipients or make your message feel less cohesive.

Best practices for writing sales email subject lines
Crafting a sales email subject line that works requires a mix of strategy, creativity, and consistent testing. Understanding what kind of subject line works best for your audience can dramatically improve open rates and engagement.
Here are the best practices you should follow when writing your subject lines to increase open rates and engagement:
1. Be clear and specific about the value
Your subject line should clearly communicate what the recipient will gain by opening the email.
Avoid vague or generic phrases. Instead, focus on how the email will benefit them, whether it’s a solution to a pain point or a valuable resource.
2. Personalize when possible
A personalized subject line grabs attention because it feels more tailored to the recipient. Using their name, company, or a specific reference to their business shows that the email is relevant and not a generic mass email.
3. Avoid excessive punctuation or clickbait
Avoid using too many exclamation marks, all caps, or misleading phrases in your subject lines.
These tactics can come across as spammy and often trigger spam filters, preventing your email from being delivered to the recipient’s inbox.
4. Test different subject lines
A/B testing different subject lines allows you to find the best-performing version. Test various combinations of keywords, tone, and structure to identify what resonates most with your audience.
This iterative approach helps you continually refine your subject lines.
5. Avoid being too sales-focused
A subject line that is too pushy or overtly sales-driven can turn people off.
Instead of focusing solely on making a sale, try offering value or presenting a solution that helps solve a problem.

What makes a good email subject line for sales?
A good email subject line for sales grabs attention immediately. It speaks directly to the recipient, offering value while sparking curiosity.
The key is to focus on what will resonate with your target audience. Start by addressing their specific pain points or offering a particular benefit that makes them want to open your email.
The best sales email subject lines don’t waste time with fluff; they get straight to the point.
Incorporating action-oriented language and making the subject line feel personal or time-sensitive can also work wonders.
A perfect email subject line makes the reader feel like they’re missing out if they don’t engage, whether it’s through an exclusive offer or a compelling call to action.
Additionally, keeping it short and relevant ensures that your email doesn’t get lost in the crowd, especially when competing with others in the inbox.
Why do email subject lines matter in sales?
Email subject lines are crucial because they decide whether your email gets opened or ignored.
A compelling subject line catches the reader’s attention and entices them to engage with the content inside. Without a strong email subject line, even the best email can go unnoticed.
A well-written subject line speaks directly to the recipient’s needs or interests, making them more likely to open your email.
It's your first impression, so a clear, attention-grabbing subject line can significantly improve your chances of driving meaningful engagement and sales.
How to write subject lines for sales?
Writing effective subject lines for sales is an essential skill that can significantly impact your email marketing results.
Here's how you can craft subject lines that capture attention and drive engagement:
1. Understand your audience
Before you write a single subject line, it’s crucial to understand who you're writing for. Each prospect is different, and so are their needs and challenges.
The most effective email subject lines for sales address a specific pain point or offer a solution to something your prospect is actively dealing with.
By tapping into the mindset of your audience, you ensure your sales email subject lines resonate with what they care about most.
2. Keep it short and clear
People are busy and often skim through their inboxes quickly, so your subject line should be short enough to be read at a glance.
A subject line that’s too long or unclear can be ignored or cut off entirely. Keep it concise and direct.
For example, instead of “Here’s a great solution to increase your sales in just a few easy steps,” a shorter version like “Boost your sales with these proven methods” is more effective.
3. Make it compelling
A well-crafted subject line is not just informative; it’s designed to spark curiosity or action. Compelling subject lines use strong language that inspires urgency or highlights value.
For example, “Exclusive offer for new customers” is more compelling than simply “New customer discount.”
4. Personalize the subject line
Personalization is a powerful tool in sales emails. A personalized email subject line draws attention by making the recipient feel that the email was meant specifically for them.
Using the recipient's name or the company name in the subject line increases relevance and makes the email feel more personalized.
Personalization can significantly increase open rates because it makes the subject line feel more direct and relevant to the individual receiving it.
5. Create curiosity or intrigue
The most effective subject lines are often those that make the reader curious enough to open the email.
This can be achieved by implying that something is interesting, valuable, or useful inside the email without revealing everything in the subject line.
Effective curiosity-driven subject lines strike the perfect balance between intrigue and clarity, prompting recipients to learn more.
6. Test and optimize
Not every subject line works equally well for every audience. What resonates with one segment might not work with another, which is why testing is essential.
A/B testing subject lines allows you to compare different versions and see which one performs better.
For example, you might discover that your audience responds better to subject lines that include action verbs or questions rather than just straightforward statements.
By regularly testing and optimizing your subject lines, you ensure that your emails are as effective as possible in driving engagement and conversions.

Common mistakes to avoid in sales email subject lines
Crafting an effective sales email subject line is crucial for success, but many marketers and sales professionals make some common mistakes that can negatively impact their email engagement rates.
By being aware of these errors, you can improve your chances of getting your emails opened and read. Here are some common mistakes to avoid:
1. Being too vague
A subject line that’s too vague doesn’t give the recipient enough reason to open the email. If your subject line doesn’t indicate the value or purpose of the email, your prospect is likely to ignore it.
For example, subject lines like “Important information” or “You need to see this” are generic and don't offer enough detail to spark curiosity.
Instead, be specific and let your recipient know why the email is worth their attention.
2. Using excessive punctuation or all caps
While it’s essential to stand out, using excessive punctuation or writing in all caps can make your email look unprofessional or spammy.
Subject lines like “SALE!!! HUGE DISCOUNT!!!!” or “GET YOUR FREE GIFT NOW!!!” can be off-putting and often trigger spam filters, preventing your email from even reaching the inbox.
Keep your subject lines clean and professional, and avoid overusing symbols like exclamation marks or question marks.
3. Making it too long
Long subject lines get cut off, especially on mobile devices, where space is limited. If the recipient can’t see the whole subject line, they may not understand the value of your email or may skip over it.
Ideally, keep your subject lines under 50 characters to ensure they display properly in the inbox and make an immediate impact.
4. Being overly salesy or pushy
Subject lines that are too aggressive or overtly sales-focused can turn prospects off. Phrases like “Buy now!” or “Limited time offer!” can sound like brutal sales tactics and may cause recipients to hesitate.
While urgency can be compelling, it’s essential to strike a balance. Focus on building a relationship with your prospects by offering value and providing helpful information rather than just pushing for a sale in the subject line.
5. Failing to personalize
Personalization can significantly enhance the effectiveness of your subject lines, but many marketers overlook this opportunity.
A generic, impersonal subject line is less likely to capture attention. By adding a prospect’s name or referencing their company, you make the email feel more tailored to them.
Personalized subject lines have been shown to increase open rates because they feel more relevant and engaging.
6. Being misleading
Misleading subject lines are a surefire way to lose trust and damage your reputation. If your subject line promises something that isn’t delivered in the email, your recipients will feel deceived, and they may unsubscribe or mark your emails as spam.
Always ensure your subject line accurately reflects the content inside the email to maintain credibility and trust with your audience.
7. Ignoring mobile optimization
With the rise of mobile email usage, it’s essential to ensure your subject lines are optimized for smaller screens. If your subject line is too long or unclear, it may be cut off, making it less effective.
Always check how your subject line appears on mobile devices and ensure it’s concise and clear enough to grab attention on the go.
8. Using too many generic phrases
Phrases like “Important update” or “Check this out” can come across as overused and uninteresting. While these terms might be attention-grabbing initially, they fail to stand out in a crowded inbox.
Instead, try to come up with unique and creative subject lines that reflect the value of your email while keeping it fresh and relevant.
9. Overcomplicating the language
Complex or overly technical language can confuse your audience and make your subject line less appealing. Keep things simple and easy to understand.
Your goal is to quickly communicate what the email is about and why it’s worth opening, not to make it hard for the recipient to decode your message.
10. Not testing subject lines
Finally, not testing your subject lines is a common mistake that can hold back your email marketing efforts. Without testing, it’s hard to know what resonates with your audience.
Running A/B tests on different subject lines can help you determine which ones drive the best engagement. Small changes, such as tweaking the wording or adjusting the tone, can have a significant impact on your open rates.
Do’s and Don’ts for writing sales email subject lines
Writing effective sales email subject lines is crucial for getting your emails opened and engaging your audience. To help you craft subject lines that drive results, here are some key do’s and don’ts to follow:
Do’s
A great email subject line should be clear and concise, getting straight to the point. Keeping it brief ensures the recipient knows what the email is about without getting lost in a long message, especially when reading on mobile devices.
Personalization can significantly increase your open rates. Adding a recipient's name or mentioning their company name makes the email feel more relevant and increases the chances of it being opened. For example, "John, here's a quick tip for [Company Name]."
Spark curiosity by hinting at something valuable or interesting inside the email. Use subject lines that leave the reader wanting more, such as “You won’t believe what we can do for you” or “Here’s a simple solution to your problem.”
Strong, action-oriented language encourages the reader to take the next step. Phrases like “Claim your discount now” or “Start improving today” create a sense of urgency and encourage the recipient to open the email.
Always test subject lines to see what resonates best with your audience. Run A/B tests on different versions to determine which subject lines generate the highest engagement.
If it fits the context, creating urgency can prompt recipients to open your email immediately. Words like “limited time” or “act fast” can make the email feel time-sensitive and encourage immediate action.
Don'ts
1. Don't be vague
Avoid vague subject lines that don’t give enough information about what’s inside the email. Good email subject lines for sales communicate the value of opening the email.
For instance, “Check out this new product” is much less effective than “Introducing our new product, designed to save you time.”
2. Don’t use excessive punctuation or all caps
Overusing exclamation points or writing in all caps can make your email appear unprofessional and may trigger spam filters.
Keep your subject lines clean, straightforward, and easy to read.
3. Don’t make it too long
Subject lines that are too long often get cut off, especially in mobile inboxes.
Aim for subject lines of 50 characters or less to ensure the whole message is visible and easily understood.
4. Don’t be overly salesy
While sales email subject lines should be persuasive, avoid being too pushy. Words like “Buy now!” or “Exclusive offer” can sound too aggressive and may drive people away.
Instead, focus on creating value and offering something helpful to your audience.
5. Don’t mislead your recipients
Misleading subject lines can quickly damage trust. Always ensure that the subject line accurately reflects the content of the email.
If your subject line promises a benefit, make sure it’s delivered in the body of the email.
6. Don’t use generic phrases
Generic subject lines like “Important update” or “Check this out” are overused and don’t stand out.
To make your subject lines more effective, be creative and unique, ensuring they immediately grab the recipient’s attention.

6. Urgency-based sales email subject lines

7. Quantified subject lines
Using numbers or statistics in your subject lines can make them more eye-catching and credible. Quantified subject lines highlight specific benefits or results.
8. Referral sales subject lines
Referral-based subject lines are an effective way to leverage existing customers to acquire new ones. These subject lines suggest that someone within the recipient’s network has recommended the solution.

Follow-up emails are often essential in the sales process. A well-crafted follow-up sales subject line can increase the chances of getting a response after an initial contact.
10. Meeting request sales subject lines

12. Social proof sales subject lines

The best keywords to use in sales email subject lines
Using the right sales email subject lines and keywords is crucial for capturing attention and driving engagement.
Here are some types of keywords you can use to enhance your subject lines, along with brief explanations:
1. Action-oriented keywords
These keywords encourage immediate action and can help prompt the recipient to open your email without delay.
These types of subject lines are effective for re-engaging prospects who haven’t responded to previous emails.
Examples: “Get started,” “Claim now,” “Start today,” “Download now”
2. Benefit-driven keywords
Benefit-focused keywords communicate the value that recipients will gain by opening the email. Highlighting the clear value proposition behind your offer drives action.
For example, offering solutions to a prospect's desire or improving their business can attract attention.
3. Urgency-based keywords
Urgency keywords push recipients to act fast before they miss out.
This type of subject line is often used for time-sensitive offers that align with the sales cycle or promotions that are about to expire. Using phrases like “last chance” or “act now” can create a sense of urgency.
Examples: “Limited time,” “Last chance,” “Hurry,” “Act now”
4. Social proof keywords
Social proof, like “recommended by” or “trusted by others,” builds credibility and reassures the recipient that your offer is reliable.
This can be especially helpful when you want to establish a competitive advantage or leverage success stories.
Examples: “Proven,” “Top-rated,” “Most trusted,” “Recommended by”
5. Personalization keywords
Personalized subject lines make the recipient feel that the message is specifically relevant to them.
Addressing the prospect's time and showing that you understand their needs helps make the email feel more tailored.
A meeting request subject line can also be personalized for more effective follow-ups.
6. Free offer keywords
Offering something free can spark interest and increase open rates. When you offer a free idea or consultation, you provide immediate value, making the email even more appealing.
Just ensure your email subject line doesn’t come across as too “salesy” to avoid being flagged as spam.
Examples: “Free trial,” “Free gift,” “Free resources,” “Free consultation”
The role of emojis in sales email subject lines
Emojis have become a popular addition to sales email subject lines due to their ability to catch attention and convey emotions in a visually engaging way.
When used correctly, emojis can make your subject line stand out in a crowded inbox and add a layer of personality to your message.
However, it's essential to use emojis strategically to ensure that they enhance your subject line rather than detract from it.
Benefits of using emojis
1. Increased visibility
Emojis can help your subject line stand out among the sea of text-based emails in a recipient’s inbox. By adding visual elements, your email is more likely to catch the prospect’s attention, especially in mobile inboxes where space is limited.
2. Humanizes the message
Emojis can make your sales email feel more personal and less formal. This can help establish a friendly connection with the recipient, which is particularly important when you’re trying to build rapport as a sales rep.
3. Conveys emotion quickly
Emojis help convey emotions or tone, providing clarity in a subject line. For example, using a smiley face 😊 or a thumbs-up 👍 can give your email a positive, upbeat feel, which could be perfect for offering an exclusive deal or celebrating an achievement.
4. Saves space
Emojis can replace words, making your subject line more concise. This can help you create a great subject line without exceeding the character limit, especially on mobile devices where space is crucial.
5. Increases engagement
Catchy email subject lines with emojis can lead to higher open rates, as they immediately grab attention. A well-chosen emoji can also give the recipient a sense of curiosity or excitement, prompting them to open the email to see what’s inside.
Considerations
1. Don’t overdo it
Using too many emojis can make your subject line look cluttered or spammy. Maintain focus on clarity and value while incorporating a few carefully selected emojis to enhance your message.
2. Match the tone
Emojis should align with the tone of your email. If you're addressing a serious prospect's pain points, avoid emojis that could undermine the professionalism of your message. Conversely, if your email offers a free idea or valuable insights, emojis can enhance the friendly, approachable tone.
3. Know your audience
Consider the preferences of your prospect’s company and your target demographic. Some industries or professionals may appreciate a more formal approach, while others may respond better to the fun and engaging touch of emojis.
4. Stay on brand
Ensure that the emojis you use are consistent with your overall brand voice. Using emojis that don't align with your approach can confuse recipients or make your message feel less cohesive.

Here are the best practices you should follow when writing your subject lines to increase open rates and engagement:
1. Be clear and specific about the value
Your subject line should clearly communicate what the recipient will gain by opening the email.
Avoid vague or generic phrases. Instead, focus on how the email will benefit them, whether it’s a solution to a pain point or a valuable resource.

A personalized subject line grabs attention because it feels more tailored to the recipient. Using their name, company, or a specific reference to their business shows that the email is relevant and not a generic mass email.

Avoid using too many exclamation marks, all caps, or misleading phrases in your subject lines.
These tactics can come across as spammy and often trigger spam filters, preventing your email from being delivered to the recipient’s inbox.

A/B testing different subject lines allows you to find the best-performing version. Test various combinations of keywords, tone, and structure to identify what resonates most with your audience.
This iterative approach helps you continually refine your subject lines.
5. Avoid being too sales-focused
A subject line that is too pushy or overtly sales-driven can turn people off.
Instead of focusing solely on making a sale, try offering value or presenting a solution that helps solve a problem.
