Email subject lines for B2B audiences are important — more important than you might think. They can make or break your whole email marketing campaign. So with no further due, let’s dive right into it and find the best practices for B2B email subject lines and explore some real life examples.

The importance of subject lines for B2B emails

The subject line is the first interaction a user has with your email — the first and pretty much decisive. Based on the subject line, people choose whether they should open the email, leave it unread or send it to spam. 

What else is essential to know about subject lines in B2B emails? Here are some important stats for you to consider when planning your B2B email marketing

✅ B2B marketing emails see a higher click-to-open ratio: in 2020, it increased by 11,9% 

85% of B2B marketers use email marketing software in their work

✅ For 81% of B2B marketers, email newsletters are the most-used type of content 

90% of B2B companies see email engagement as a content performance measure — it’s the most popular metric

So now we’re clear — subject lines are just as important for B2B emails as for B2C — let’s get down to business and explore the best strategies to compose engaging subject lines.

How to make your B2B email subject lines actually work and boost sales

1. Avoid the spam folder at all costs

Ok, this seems obvious, but we’re going to remind you to check the spamminess of your subject line anyway. Because if your email goes to the spam folder — there’s no coming back for it. 

Avoid using all caps in your subject lines, and words like “lowest prices”, “click here”, “risk-free”, “sign-up now”, and others. They make your email look shady and fishy.

You can use tools like this Subject line tester to check your subject line and see if it’s viable.

2. Spice it up with power words and emotional triggers

Find words that will immediately grab the attention of your audience. When composing your subject lines for outreach emails, keep in mind that you’re writing for a business representative. 

People with buying power don’t like to feel like they’re getting tricked or bombarded with irrelevant offers. Instead, try to establish trust and a sense of reliance. Find power words that trigger these emotions. For instance, you could use words like “proven”, “scientific”, or “guaranteed” when suitable.

3. Experiment with formats

Research what kind of subject lines work better with your audience. What makes your receivers open emails — intriguing questions or straightforward statements? Studies show that simple and straightforward subject lines work better — but this may not apply to your audience. It’s always worth testing out.

Aside from that, try adding emojis, joking around, or even leaving the subject line completely empty. See what works with your audience. 

4. Don’t experiment blindly — A/B test

How to take the most out of your experiments with formats and power words? A/B tests!

Create two versions of a subject line for one outreach email to test a hypothesis. For instance, you can compare the performance of creative subject lines with simple ones, emojis with no emojis, and personalization with no personalization. 

Remember to try only one hypothesis at once. Don’t try emojis, personalization, and creativity all during one A/B test. Instead, run three tests with three different emails. This way, you will be sure which tool works for sure and which doesn’t.

5. Personalize it

Personalization is more than just adding the subscribers’ names in the subject lines. Use other data you have on your recipients to make you subject lines truly tailored: 

  • Their position in the company — Are you a sales manager? Here are three new tools to boost your performance
  • Their goals — You can improve your subject line game in just 3 steps 
  • Their pain points — How to fix cart abandonment rate with re-engagement emails

The golden rule of personalized subject lines is to match them with the contents of the email carefully. When promising special tailored offers in the subject line — make sure that it’s not just a Christmas sale, but actually a special offer created for your subscribers.

Adding subscribers’ names to the subject line could be a nice touch of personalisation that does not oblige you to tailor the whole content of the email for each user

6. Keep it short — and even shorter

On desktop devices, the character limitation for subject lines is 60 symbols. For mobile devices, it’s 30 symbols. 

With a lot of business representatives checking their mailboxes on their smartphones and tablets, it makes sense to keep your subject lines as short as possible.

However short the subject line is, it should still make sense. Otherwise, what’s the point?

7. Make it about them (not you)

No offense, but… your subscribers don’t really care about your goals and achievements. They care about their goals and problems and look for ways to reach them. So talk about them, not your product. 

Ask subscribers personal questions about their business and their achievements. Center your subject lines around their metrics. Show interest in their problems.

8. Don’t clickbait

Write subject lines that match the content of the email and don’t give promises you can’t keep. You know the deal with clickbaits — they work if you use them once, but long-term, it’s a losing strategy. 

When it comes to B2B emails, it’s usually better to keep the subject line simple and more straightforward. Too creative email headings may confuse or, worse, annoy this kind of audience and will deprive you from prospects to get leads.

9. Add some numbers

If you have some great numbers to back up your message in the subject line — use them! This applies not only to discounts. 

People tend to trust numbers more than just big words. So spice it up with some impressive data whenever you can.

Best subject lines for every type of email

Now that we went through the basics of B2B email subject lines, let’s see how they can be used in each type of email in B2B marketing.  

Cold emails

The first email with a new recipient has to be very engaging — in one subject line, use not one, but two or three of the tips mentioned above. 

  1. Hi, {Name}! We’ve met at {event name}

Personalize your email subject lines with more than just a recipient’s name. If you got their contact on some event, mention it. 

  1. 9 reasons you’re not {pain point}

Segment your audience and refer to each recipient’s pain points — that’s also a way of personalization. Also, don’t forget to use numbers, when you can!

Partnership emails

In emails where you propose a collaboration with recipients, talk about them and their goals first. Another strategy is being straightforward and just announcing the event or collaboration you’re inviting to.

  1. Boost your sales at {event name}

Try mentioning both your proposal — in this case, it’s the event — and the profit for the recipient. 

  1. Here’s how {your service} will help you with {pain point}

Mention the pain points to get a higher open rate

Newsletters

When composing subject lines for B2B newsletters, add some catchy and funny things from the contents of the email. Add some intrigue to it! 

And, please, don’t use the words “newsletter” or “highlights of the month” in the subject line — the recipient doesn’t really care about the format of the email, and you’re just wasting precious characters. Instead, add some of your signature style to the heading! 

  1. It’s split into two, but it’s not broken. What is it? 👀

Add a little riddle to get your subscribers wondering. Also, newsletter subject lines are a good place to use emojis. 

  1. So much data, so little time…

Both a riddle and a pain point added. Combo!

  1. {Name}, let’s discuss your next steps with {your company name}

Make it sound personal.

Re-engagement emails

With a B2B audience, the “we miss you” re-engagement emails won’t really work, so make sure to keep your tone of voice right and still re-engage. 

  1. Since we last saw you, {number} of businesses fixed their {pain point} with {your company}

Make them see what they’re missing out on from the first line! 

  1. We haven’t seen you in a while. Let’s check on your goals!

Don’t hope for late replies — always follow up when you don’t have a reply. Find ways to engage people who are slowly losing interest in your offer. Here’s how you can do it: 

  1. Would you like to try {your service} for free? 

Re-engage your B2B subscribers with special offers or even with your usual free trial — the goal is to make it feel tailored for each recipient.

  • A lot of business professionals decide to open your emails based on the subject lines. 
  • Keep your subject lines sweet and short, as a lot of people from the B2B audience read emails on mobile devices. 
  • Personalize your emails, add numbers to them, and experiment with formats to find the best ways to engage your audience. Clickbaits and spammy subject lines, on the other hand, might make you lose subscribers.
