Did you know that 47% of email users open an email based on the subject line?

In today’s internet age, creating an eye-catching subject line is more important than ever.

What makes a subject line effective?

In this blog article, we’ll discuss our best practices and top suggestions on how to write effective subject lines that get your emails opened and results for your business.

Discover how to improve open rates, boost engagement, and ultimately meet your email marketing goals by using customized subject lines and action-oriented language.

Let’s get started.

Why Email Subject Lines Are Important?

As a marketer, it is necessary to write an email that attracts your audience’s attention.

What’s the sense of sending an email if it’s never opened?

The subject line is the first thing your recipient sees, and it influences whether or not they open your email. 

How to Write Effective Email Subject Lines?

In this article, we’ll go over some important pointers and best practices for crafting successful email subject lines that get your emails opened.

1. Keep It Short And Sweet

Keep subject lines brief and to the point.

Because most email service providers only display the first 50-60 characters of a subject line, make sure you get your point through fast.

Avoid subject lines that are extensive and rambling, making them difficult to read and understand.

Use clean, short subject lines that go straight to the point.

2. Personalize Your Subject Line

Personalizing your subject line is another excellent method to capture your audience’s attention.

Include their first name, locality, or something else that makes them feel like the email is personalized to them directly.

The research found that personalized subject lines have a 29% greater open rate than non-personalized subject lines.

So,  spend some time segmenting your email list and personalizing your subject lines.

“Why did the email subject line go to art school? To learn how to be more personalized!”


“Happy Birthday, [First Name]! Our Gift to You Inside”

“Attention [City Name]: Special Offer Just for You”

“We Thought You’d Love This, [First Name]”

3. Use Action-Oriented Language

Action-oriented language is an effective method to encourage your readers to open your email.

Use active verbs and action phrases to attract readers to click and interact. 

“Don’t miss this limited-time deal!” for example, or “Access special stuff here!” These subject lines create a sense of urgency and excitement, which can help boost open rates.

“Why did our email subject line join the military? Because it was always so action-oriented!”

4. Test And Experiment With Different Approaches

Every audience is special, and what works for one audience may not work for another.

So, always test and experiment with various ways to your email subject lines.

Experiment with different lengths, styles, and tones to find what works best for your audience.

A/B testing may also be used to test alternative subject lines on a subset of your email list before sending them to the rest of your subscribers.

5. Avoid Spam Triggers And Clickbait

Finally, avoid abusing spam triggers and clickbait in your email subject lines.

This can not only harm your brand’s reputation, but it can also cause your emails to be labeled as spam.

Avoid using all capitals, excessive punctuation, or anything else that may be seen as deceptive or manipulative.

Make your subject lines straightforward and honest, and make sure they correctly describe the content of your email.

“How do you avoid clickbait? Easy, just don’t click it.”
