Eye-сatching email subject lines

Eye-catching email subject lines

0 comment

About 105 billion emails are sent each day. To reach customers, you must provide a catchy subject line that will stand out from hundreds of other emails and inspire your readers to open the letter. Below are some essential tips on how to polish your subject lines and increase your open rate.

How email subject lines influence your open rate

Your open rate is the percentage of emails that have been opened out of the total amount of emails sent. It is a crucial metric for evaluating the success of an email marketing campaign, and here’s why.

Even if your email avoids the spam filter and reaches your reader’s mailbox, it doesn’t mean that subscribers will actually read it. However, a catchy subject line can draw attention and increase the letter’s chances of being seen, as 47% of people read emails only if they like the subject line.

21 best practices for writing catchy email subject lines

Below are some essential techniques and examples that will make your email subject lines special.

1. Start with action verbs

Start with action verbs

Action-oriented verbs (e.g. Read, Open, Grab) aim to inspire people to click and read your message by making it sound dynamic and vibrant. Actionable subject lines help readers envision themselves doing the action and, for this reason, are great at increasing your open rate. Here are some examples:

  • “Book your dream vacation today”
  • “Meet your new guide to travel the world”
  • “Get a head start on summer”

2. Make it personal

Make it personal

Personalization helps make readers feel closer to you. To do so, use names or locations in your subject lines:

  • “Travel bloggers from Europe must know that”
  • “This is where every German should go on holidays”

This method may be the best way to set up a comfortable direct conversation with your readers and make them feel special. Another way is to use personal pronouns, for example:

  • “This deal is especially for you”
  • “We know what you want for this winter holiday.”

3. Attract with numbers

3. Attract with numbers

Another effective marketing trick to win your audience is to incorporate some numbers into your subject lines:

  • “100 things to know about the modern travel community”
  • “Top 5 ways to increase your air miles”
  • “Book hotels 50% cheaper”

Numbers help your email look more valuable and can even increase the click-through rate by 36%.

4. Be clear and precise

Be clear and precise

Make your message direct and clear so that readers can easily understand what the email is about. Most people quickly look through their emails, so a long subject line with flowery language is unlikely to grab their attention for long, while a short and concise phrase will carry the message to the reader much more effectively. Here are some examples:

  • “Best holiday ideas for this summer”
  • “Life hacks to save on hotel stays”
  • “Best blogging courses”

5. Make your recipient wonder what’s inside

You don’t need to reveal all the contents of your message from the very beginning. Sometimes, in order to incentivize your reader to open the email, you’ll need to grab their attention and make them wonder what the message will be about. Consider adding some mystery with an incomplete sentence, metaphor, or ellipsis. For instance,

  • “Best destination for this summer”
  • “Overcome your competitors with this tool”
  • Or be even more mysterious with a line like “Show us yours and we’ll show you ours.”

6. Use list segmentation

To be honest, it is hard to please everyone. If you are targeting a large audience, consider segmentation, which allows you to categorize subscribers by location, demographics, etc. Then prepare different emails for each list. If used properly, this method will help you achieve a significant uplift in your email campaign.

For example, instead of using an overly general subject line, such as “Best travel ideas,” address younger travelers with “Where every millennial should travel,” middle-aged tourists with “Places to visit before you turn 40,” and seniors with “Incredible travel ideas for those who are over 50.”

7. Make it look like an offer or giveaway

Make it look like an offer or giveaway

Offers and discounts play well because people are always attracted by an opportunity to get something for free. For example, if you run a contest, reflect it in the subject line:

  • “Hurry up to claim your prize”
  • “Don’t miss the chance to win $100”

Even if you aren’t providing actual gifts, it is still possible to make the message look like a giveaway. For example, you can draw attention with a line like “An exclusive offer for you.”

8. Stay relevant to your brand

Your subject line must align with your brand, match your voice and goals, and be relevant to your niche.

For example, if you use a famous person’s name, that person should align with what you do or what kind of products you sell, not just as a means of attracting attention. Another thing to keep in mind is language: brands targeting younger audiences can use slang to make the message more relatable.

9. Add humor

Humor is another thing that helps distinguish your subject line from your competitors. A well-placed joke can earn you some major reputation points with folks on your wavelength, which will increase the likelihood of your email being read. While it might be hard to come up with comical subject lines for every newsletter, try this approach at least once to gauge the response of your specific audience. For example, try to use wordplay like in the example below:

10. Grab attention with controversy

A little bit of controversy in your subject line can be a good thing if it makes the email unexpected without being overly shocking. For example, “Everybody is lying: Why you shouldn’t believe travel bloggers.”

To use this approach correctly, you need to have a clear understanding of who your target audience is. Speaking about taboo subjects can attract people or push them away. Thus, try to consider your audience’s gender, age, nationality, religion, and other factors to avoid making your emails insulting.

11. Ask a question

Ask a question

Asking a question is another efficient way to engage your subscribers, especially if you ask something personal rather than something rhetorical. For example:

  • “Are you making these SEO mistakes?”
  • “What are you dreaming about this summer?”
  • “What are your customers saying about you?”

12. Use partial capitalization

Use partial capitalization

Capitalization is a proven way to attract attention, but remember not to get carried away. Use partial capitalization to emphasize the most important keywords that will trigger your readers’ interest. For example,

  • “Wow! These tips will help you EARN $100 a day”
  • ”DO NOT Commit These Blogging Atrocities.”

13. Make use of alliteration

Used correctly, poetic lines can capture attention just as effectively as numbers or giveaways. By adding alliteration (repeated use of consonants), you will make your subject line sound like a musical phrase (“Social Marketing: Bands, Brands, & Fans”).

14. Stick to a casual tone

Make your subject line sound like a friendly conversation with a casual tone. This may mean using personal pronouns, simple grammar, or even slang. In contrast to common, impersonal lines, write something like “Are you also thinking about hopping on a flight to Spain?” to make your message resemble a question from a friend.

15. Go minimalist with one-word subject lines

Another tactic that will differentiate you from your competitors is using one-word lines. This technique immediately attracts attention and makes your readers wonder what’s inside your message. You can combine this method with a call-to-action by using action verbs like “Open” or “Hurry,” emotive words like “Enjoy,” “Alarm,” and “Valuable,” or even greetings such as “Hey!”

16. Use scarcity tactics

Scarcity creates the illusion that you are offering a limited quantity of something important or that you are offering a limited-time offer. No one wants to miss out, which is why such an approach often works flawlessly for marketers. For example:

  • “48 hours left to get this course for free”
  • “Our promotion closes shortly.”

17. Don’t overdo it

Whatever strategy you choose, don’t go overboard. Using flowery language that is difficult to understand, exclamation points, or full capitalization will get your letter ignored or deleted, as these tactics look spammy. (“OPEN NOW AND RECEIVE A FREE TRIAL,” “50% off coupon today only!!!!!!!!”). Take advantage of spam checker tools that evaluate your email and help you avoid the spam folder.

18. Keep it short

If subject lines are too long, nobody is going to read them. Naturally, you want to say as much as possible, but so do your competitors. Stand out from the crowd by using short and informative lines. While some marketers recommend using up to 50 characters, others believe that line length should depend on the type of device most of your readers use.

19. Find the best time to send your email

Sometimes, it is all about timing. Mailchimp reports that open rates peak around 10 am, regardless of industry. Thus, 10 am might be a great time to send out your newsletter. 6 am and 8 pm also boast high open rates. As for days of the week, Tuesday and Wednesday are perfect for sending emails.
