50 of the Best Email Subject Lines for Sales and More | Nutshell (2024)

We’ve all written our fair share of email subject lines, but how good were they really? Maybe you got a couple of responses and a few clicks—except you’re not satisfied with mediocre email engagement. You want engagement metrics that really shine.

Optimizing your sales email subject lines will improve open rates, click-through rates, and the overall effectiveness of your email marketing strategy—leading to more and better customers.

Whether you’re a solopreneur, email marketer, or sales representative, this guide will help you write better subject lines that make your emails more clickable and drive business growth.

The impact of email subject lines on sales success

When an email subject line is bad, you can tell—and so can your recipients. The message is likely to go straight to the junk folder. But when you’ve crafted an engaging subject line that speaks to your contact’s needs and hooks them right from the start, you’ve struck email gold.

A successful email subject line will convince recipients to open your message, where the body of your email can then do the work of persuading them to read or click more. With a well-written subject line, you can:

• Drive higher response rates and email engagement
• Increase conversions from your sales emails, like more meetings booked and websites visited
• Solidify your company’s brand and create more positive customer experiences

5 best practices for crafting effective subject lines

When sales representatives or email marketers compose a winning subject line, they follow a few common best practices. Use the following strategies to inspire your own writing:

1. Choose language carefully

Language matters, especially when you’re trying to convince someone to open a sales or marketing email. And in the age of phishing schemes and ransomware, people are on high alert regarding the language used in emails.

Be careful what language you use in your subject lines, especially regarding:

• Keywords: While keywords may be helpful for getting your email into the right inbox, avoid overusing them. This could come across as spammy, as could clickbait-type language that overpromises and underdelivers.
• Subject line length: Subject lines should also be the right length for showing up on desktop and mobile devices. A good goal is around 60 characters.
• Emojis: Emojis can make your email stand out from the rest. But overusing them could come across as immature or spammy. Plus, emojis may not render correctly in every email inbox.

2. Command attention

Getting a recipient’s attention in the subject line is crucial for convincing them to open your email and take action. Luckily, there are lots of ways to get—and hold—someone’s attention through your subject line:

• Use personalization: Using the recipient’s name and their business name is a good strategy for encouraging a response. Check out these additional tips for sending personalized emails.
• Create urgency: A time crunch can be just what your prospect needs to take action regarding your email. Just be sure not to overwhelm the recipient or overuse this tactic, as it could become annoying.

3. Experiment to optimize

Writing effective emails is a process you can continue optimizing. It’s important to experiment with subject line content and format until you find what works.

Use subject line A/B testing to determine which style of subject line results in the most opens, clicks, or conversions. When you A/B test a subject line, you can change content, length, emoji use, word order, and more to see which version resonates best with your audience.

4. Determine the type of subject line to use

The purpose of an email subject line is to tell recipients what your email is about.

Depending on what you hope to accomplish with your email, you might use one of the following types of subject lines:

• Promotional subject line: Shares about and drives interest in a promotion
• Value-driven subject line: Explains the value you can provide your recipient and their business
• Curiosity-based subject line: Show that you have information the recipient might find valuable
• Funnel stage subject line: Demonstrate that you know where they are in the sales funnel and can provide the information they need to take the next step

5. Be interesting

You might think writing a captivating subject line is the trickiest part of all, but you don’t need to take a creative writing class to get the job done. Knowing your recipient well enough to use language that interests them is key.

Here are a few ways to make your subject line interesting:

• Show off your brand voice: Depending on your brand, a well-placed pun or joke could remind recipients of why they’re your customers.
• Share a relevant bit of industry news: Referencing a new statistic or development in your industry shows that you have important information to share.
• A question about their work or project: Demonstrate that you’re interested in what they’ve been working on, and they’ll likely reciprocate by opening your email.
• Have an ask: Have a question for your recipient? They’ll open your email to find out what it is.

Cold email subject lines

Cold emails are some of the most challenging to get right because the recipient has little or no knowledge of who you are and why you’re reaching out.

With these cold email subject lines, you’ll be well on your way to capturing your recipient’s attention and persuading them to click:

1. Hi [name], [question]?

Asking your question right in the subject line—and personalizing the email with the recipient’s name—is to the point, qualities the recipient will likely appreciate.

2. Did you find what you were looking for?

This one works great for inbound leads or website visitors.

This one’s a classic welcome email subject line that, with the right amount of personalization, can make the recipient feel right at home.

Sending this email out soon after a phone call or virtual meeting can keep your business top of mind for the recipient and puts you in a position to answer any more questions.

26. I thought about what you said

This subject line works because the prospect isn’t sure exactly what you’re referring to, encouraging them to open the email. And they might be ready to hear your idea.

If you’re networking, this email makes the recipient feel like the expert. It might be the nudge they need to reply to you.

This subject line functions like the one above, and is a little more specific about how you’d like to talk with the prospect.

35. Have [number] minutes to talk [industry/pain point]?

This casual meeting request works best when you already have a relationship with a recipient.

36. Got a couple of minutes for me?

This email puts you at the recipient’s mercy, but it could work if you really do only need a couple of minutes of their time.

37. Is [result] for [prospect’s company worth 20 minutes of your time?

When they stop and think about it, the opportunity to increase sales by 20% using your product probably is worth a 20-minute meeting. Only use this line if you can really deliver the results you’re promising.

38. This deal is running out of time—want to talk it over?

Another way to add a sense of urgency. Of course, only use this if the deal really is expiring.

39. Let’s look at [prospect’s company]’s goals for next quarter

The actual meeting request comes later in the email, but this subject line shows that you’re available and willing to help the recipient achieve more.

40. Jam-packed schedule? I’m flexible

If you already requested a meeting with a prospect and haven’t received a response, they could just be busy or buried in other messages that need more immediate attention. Giving them some flexibility might make a meeting more likely.

41. Let’s build a plan for [goal]

Show you’re ready to get to work helping your prospect.

This one is best saved for early in the sales process when you’re still generating interest, like when you’re working toward booking an initial meeting.

45. Have time to discuss [prospect’s company]’s success?

This subject line shows you want to partner in their business success.

Email subject lines after no response

Checking on your leads after hearing no response can feel like walking around in the dark. These subject lines improve your chances of finding the light at the end of the tunnel.

46. If you change your mind about partnering with [your company]

When a recipient just isn’t showing interest, try to renew it by reminding them of the results they can achieve with your help.

47. Not feeling a connection?

If your product just isn’t the solution the prospect needs, you can still close the relationship on a positive note with a clever goodbye message. It might even keep other opportunities open down the line.

48. This email contains the secrets of the universe… or at least [industry/pain point]

Poke fun at yourself by overstating what your email is about. The humor could make the prospect want to work with you after all.

49. Am I making the right assumption?

If you’re only hearing crickets, verify with the recipient that your product or solution just isn’t a priority for their business at the moment.

50. Warning: puppies inside

This subject line could work as a last-ditch effort to earn a second look. Because who doesn’t love a GIF of puppies (or whatever baby animal you’d like)?

How to analyze email subject line performance

You feel like you’ve written some really good email subject lines. Now how do you determine their success? Here are the most important ways to know whether your approach is working:

• Track key metrics: Make sure you’re tracking important email engagement metrics like click, open, conversion, and response rate.
• Use data to refine your strategy: Once you’ve gathered these metrics, identify trends so you can improve your approach. Maybe a casual approach works for some prospects but not others.
• Choose the right tools: Using the right email marketing tool can make all the difference for sales email success. These platforms often have email marketing features like bulk emailing, A/B testing, email automation, click tracking and notifications, and an AI writing assistant.
