How to Write Email Subject Lines That Get Clicked

Start With Strong First Impressions

Your subject line is the first thing people see in their inbox.
A strong email subject line grabs attention and sparks curiosity.
Use power words, personalization, or urgency to stand out.
Keep it short—under 50 characters is ideal for mobile users.
A catchy subject line boosts email open rates dramatically.

Know Your Audience and Their Interests

Effective subject lines speak directly to your target audience.
Think about their needs, pain points, and what makes them click.
Use language that feels personal and relatable.
Segment your audience to send more relevant messages.
The more specific the subject, the better the engagement.

Use Numbers and Emojis Wisely

Numbers, like “5 Tips” or “Save 30%,” make subject lines more appealing.
They promise value in a clear, easy-to-read format.
Emojis can make emails more eye-catching in crowded inboxes.
But don’t overdo it—too many can feel spammy.
Test both options to see what works best for your audience.

Run A/B Tests Regularly

A/B testing helps you compare two subject lines for performance.
Change only one element—like wording, tone, or punctuation—for accurate results.
Send version A to half your list and version B to the other.
Track open rates to see which performs better.
This method helps you refine your email subject strategies over time.

Avoid Spam Triggers

Stay away from all caps, excessive exclamation marks, and spammy words like “Free!!!”
These can send your emails straight to the junk folder.
Make sure your subject line matches the content of your email.
Be honest, clear, and creative—don’t mislead readers.
Avoiding spam triggers keeps your open rates healthy and consistent.
