A salesperson’s most important tool is email. It’s likely that you’ll mail a large number of them. And a significant proportion of emails will be sent to prospects with whom you have no prior connection. That is, they are unsolicited emails. And what is the most important factor in determining whether or not a cold email gets read? Subject lines for cold emails.

This post is for you if you are a sales development rep or an account executive.

I’ll break down seven different kinds of cold email subject lines and explain why they work for salespeople. Plus, from myself and other sales professionals, I’ve included 37 samples of the greatest cold email subject lines for sales.

What Is the Definition of a Cold Email?

A cold sales email is one sent to a prospect with whom you have not previously established a connection. It’s asking people to react only on the basis of the message’s substance. As a consequence, it has a little probability of succeeding. As a result, the subject line is very important.

According to statistics collected by Anum Hussain for HubSpot, “33 percent of email recipients open an email based on the subject line alone,” according to Kevin George of Email Monks.

Why Should You Send Cold Emails?

It’s all about the statistics. Each cold email has a little probability of succeeding, but they’re also quick to send. They spread your organization’s name far and wide, and you only need a small number of prospects to engage to make them profitable.

How to Write the Most Effective Cold Email Subject Lines

A subject line should pique the reader’s interest. It should test them and inform them that there is important information in the body of the email. It may offer answers, fascinate them, or inspire them, but it must elicit some kind of emotional response. These are desirable qualities in a cold email subject line:


An effective email subject line makes the recipient ponder. It doesn’t provide all of the facts, but it does provide enough to pique their interest.


The prospect must be interested in the offer. It must provide them with something they want. Some emails don’t reveal what they’re about at all, which is OK, but if you’re going to make an offer, it better be excellent.


Everyone enjoys hearing their own name. And everyone has a passion for something. You’re in business if you can tap into it with customized email strategies.


When the subject is interested, any offer must land. As a result, you must come at the appropriate time in their purchasing cycle and day. You should speak about something they’re currently interested in.


If they don’t open your email right away, they’re unlikely to open it at all. You’ll have a far greater chance if you can instill fear of losing out if they don’t open right away.

Examples of Cold Email Subject Lines

Here are 37 of the greatest cold email subject lines, divided into seven categories:

All of these attention-getting subject lines have been tried and tested and have shown to be effective.

The Problem

All of the following cold email subject lines ask a leading question that will entice prospects to click:

1. “For [prospect], I have a technical question.”

2. “Are you committing any of these errors?”

3. “Are you able to assist me?”

4. “Did you know XYZ Corporation was involved?”

5. “Do you see this as a challenge?”

Why Does It Work?

Mark Kosoglow believes:

“Everyone wants to express their point of view. The mention of a question that must be answered piques the recipient’s interest. They’re more inclined to read the email in order to see whether they can demonstrate their knowledge by responding to your question.”

Over the course of a single campaign, Kosoglow received a 30% open rate on 4,250 emails.

Keep in mind the following:

  • You don’t have to directly ask a question. You may inform the subject that a body copy will be included.
  • Pose an open-ended inquiry to your audience. Questions that may be answered with a simple “yes” or “no” do not pique the prospect’s interest.
  • Make sure you respond to the question promptly in the email body.

However, if you get these components perfect, you may get comparable effects as Kosoglow.

The Call to Action

The recipient’s name, title, or other personal information appears in the subject line of each of these emails (often added through the use of a merge field).

6. “If you had an additional $1,000, what would you do?”

7. “Take a look at that, [initial name]”

“Special savings for [first name]” is number eight.

9. “I put together a special report for you, [first name]”

10. “[First name], I calculated your return on investment.”

11. “Do you want wider margins, [first name]?”

Why Does It Work?

According to Invesp’s Khalid Saleh, “emails with customized subject lines are 22 percent more likely to be opened.”

It’s a no-brainer why personal callouts work: we’re all programmed to watch out for ourselves. Generic-sounding email content is less likely to grab our attention than those that seem to be customized precisely to our requirements.

The Shorty is a fictional character.

A subject line that is no more than three words long may be effective.

12. “Hey”

13. “Are you prepared?”

14. “My greatest blunder”

“Priorities” is number fifteen.

Why Does It Work?

Short subject lines are more considerate of your receivers’ time and have a more relaxed, conversational tone than lengthier ones (which may read more like slick copywriting).

Bryan Harris of Videofruit is a fan:

“When writing to a single person, I aim to keep my subject lines under four words… This is a lot faster to write, and it comes off as more conversational when I’m speaking with them.”

The Relationship

Whether it’s a recommendation, a reference to shared involvement in an event, or a reference to an online forum you both participated in, a subject line that implies a link between the sender and receiver has a significant impact.

16. “Mutual link with [connection name]”

17. “Did you have a good time at [recent event]?”

18. “I just read your remark on [business blog],” says the author.

19. “[name of mutual contact] suggested that I ask you this question”

20. “Have you ever worked with [name of common acquaintance]?”

Why Does It Work?

When people believe they are particularly equipped to assist others, they are much more driven to do so. By eliminating all or part of the “unknown” element of cold communications, email subject lines that imply a common relationship help overcome the initial mistrust most individuals have of commercial emails.

It’s worth noting that the power of connection may be readily misused. Instead than doubling back on a discussion that is at best shaky, use it as a jumping off point for a new one. And never claim you were advised to join by a common connection until you’ve double-checked with that connection to make sure it’s alright.

The Argument for Benefits

This email subject line provides the receiver with a clear and convincing advantage.

21. “Business Inc.’s new HR strategy.”

22. “ABC Corporation saves $25,000.”

“An all-time income record for Organization XYZ” says number 23.

24. “There will be no more lengthy meetings.”

25. “For Company X, 19 additional hours of selling time each month”

26. “The hunt for signatures has come to an end.”

Why Does It Work?

Subject lines for benefit propositions take advantage of people’s inherent need to know “what’s in it for me?” You may see this power for yourself if you look at the cold emails that grab your attention the most. Are you more inclined to click on messages with general subject lines or messages with subject lines that specifically address one of your pain points?


These chilly email subject lines congratulate the receiver on a recent achievement.

Subject Lines to Consider:

“Congratulations on the good news,” says number 27. “Congratulations on your book deal,” says number 28.

28. “Congratulations – I just saw you on [leading website in your industry]”

29. “I really enjoyed your talk at [name of a conference or event]”

30. “Way to go – just saw you released [a product or piece of content]”

31. “I just wanted to express how much I appreciate how you [done something]”

Why Does It Work?

Who doesn’t like being complimented?

Using congrats in your subject lines, as seen in the examples above, takes a little more research since you’ll need to keep on top of your top leads’ actions. As a result, this subject line style is particularly useful as a subject line for follow-up emails. Even if you started the discussion using one of the other methods listed above, you can keep it going by reaching out anytime you hear anything positive about your chances.

Request for a Meeting

These chilly email subject lines request a meeting in the near future.

Subject Lines to Consider:

32. “Do you have 5 minutes, [Recipient Name]?”

33. “Request for a meeting: [your name] + [name of the recipient]”

34. “Can we meet?” says [Recipient Name].

35. “Can I show you anything next week?” says the narrator.

36. “Can we meet on Tuesday?”

“Following up on our meeting” (number 37).

Why Does It Work?

Directness is appreciated by certain individuals. Why not come out and say it in your subject line if you’re going to ask them for a meeting?

Disclaimer: This only works if the content is very relevant, well-researched, and does not come off as spam.

Furthermore, meeting-based subject lines are more helpful after a meeting since you can utilize the relationship you’ve established to drive follow-up opens.

As you can see from the examples above, there is no such thing as a “one-size-fits-all” formula for writing effective sales email subject lines. Some of the examples I’ve provided aren’t appropriate for your company, while others integrate many of these aspects into a single design.

Use these structures as a starting point, but keep in mind that testing yields the greatest results. If you’re serious about cold email success, you should work to enhance your performance by iterating as you go.
