When email recipients receive your email in their inbox, the only thing they see is the subject line and preheader. Because email inboxes get hundreds, if not thousands, of emails per day, email subject lines that are both catchy and succinct are more important than ever. This single line of content can frequently determine whether an email is opened or discarded (or worse, to spam).

Email subject lines can have a tremendous impact on your readers. The words you pick in your email subject lines can have a big impact on whether or not your efforts pay off. If your target audience does not open the email, no matter how brilliant or well-crafted your email campaigns are, they are meaningless. Spending a little extra time on your email subject lines will encourage more consumers to open your emails, prevent emails from going to spam, and ensure that your message reaches the proper individuals.

How to Make a Good Email Subject Line?

Consider the 12 suggestions below as modifications you can apply to your subject lines. Each of these subject line suggestions is intended to make people notice and open your email.

1. Make Your Topic Lines Shorter

What is the point of having a subject line if no one can read it? People frequently check their emails on mobile devices, swiping right past emails that do not elicit a sense of urgency. Keep your subject line around 40 characters, or roughly five to seven words, to avoid it being chopped short. Your readers want to rapidly browse through their inboxes. Subject lines with simply one or two words can sometimes stand out and generate the most engagement.

2. Avoid Using Spam Words in Email Subject Lines

Subject lines that are of aggressive sales types are frequently recognized as spam. That means you should avoid using exclamation points and all caps, as well as an overtly promotional language like "Buy now" or "Free." These are tried-and-true methods for ensuring that your marketing emails wind up in the spam folder. Rather than focusing on promotion, provide your skills and share knowledge that your audience will find beneficial.

3. In the Subject Line, ask Open-ended Inquiries

Why should you include a question in your email subject line? Questions are an excellent method to draw your readers' attention and stir their interest. Questions on their own also feel incomplete. Including a query encourages people to open the email in search of an answer.

4. Include a Deadline

Given that there are numerous distractions between you and your readers. The deadline method instills a sense of urgency in readers, encouraging them to prioritize your email.

A series of emails will almost certainly be part of a successful promotional campaign for an event or a special offer. You can make an initial statement informing folks of an approaching date. As the deadline approaches, send a "last chance" follow-up email to remind users about the promotion. Don't be scared to set a turnaround time of as little as 24 hours. "Now or never" expressions are frequently the most effective.

5. Use a Teaser Subject Line to Get Recipients to Open Your Email

Consider why people enjoy movie previews but despise ads. It's more effective to pull folks in with a preview than to provide the punchline right away. Great topic lines accomplish this. Try to think of anything that would pique your readers' curiosity.

6. Give a Firm Command of Your Subject

Some people, on the other hand, respond best to detailed directions. If your email has a direct call to action, such as urging them to purchase event tickets, don't be hesitant to let your email subject line reflect that.

7. Include Something Useful in Your Topic Line

You may already be aware that giving something of value to your audience is an important component of a strong content marketing plan. Think about what your viewers need right now and tease a solution in your email subject line.

8. Make an Announcement Directly in the Subject Line

If you have anything new and intriguing to say about your company or group, put it in the subject line. Although it can be difficult to produce personalized emails for a large marketing email list, sharing news with email subscribers is a wonderful approach to improve that sense of personalization, as readers will feel like they're among the first to learn about this deal.

9. Make Your Email Inbox Stand Out

To write effective subject lines, you must first comprehend two concepts:

  • Who is your target audience?
  • What can your company provide them that they can't obtain anywhere else?

Consider what your company is renowned for and emphasize that in your subject line. Don't be hesitant to include your brand name right in the subject line, especially if it's well-known. Many individuals will read emails based just on the sender, so don't pass up the opportunity to emphasize your specific brand.

10. Make a Joke in Your Email Subject Line

Most individuals aren't laughing when they go through their email inbox. That implies you'll get a lot of attention if you can come up with a clever topic line.

Okay, so you might not be able to make your audience laugh, but you might be able to persuade them to open the email by making them smile with a joke that isn't completely cringe-worthy. Depending on the tone you want to set for your company, you might try out some puns or wordplay to generate some laughs and engagement from your contacts.

11. Say Something Surprising or Intriguing

If being hilarious isn't your thing, why not try surprising? This might be anything from a little-known fact about your sector to an eye-opening statistic or just something customers aren't expecting to hear from a sales email. Sharing something surprising increases the likelihood that your readers will want to read further. The uniqueness factor will also boost the likelihood that people will remember your email in the future.

12. Include Video and other Multimedia in the Subject Line of Your Email

Did you know that simply putting the term "video" in your email subject line can increase opens by up to double? Including a video, linking to a presentation or podcast, or including a helpful guide are all excellent methods to diversify and engage your email content. So, if you're going above and beyond simple text emails, make sure you mention your contacts directly in the subject line so they don't miss out!
