An eye-catching subject line is the one that gets your subscriber to open your email out of everything in their inbox. It’s short and specific, and it gives them a clear reason to open.<\/p>\n\n

Here are 20 formulas with examples to copy, a table by type of email, what to avoid and how to test your subject lines.<\/p>\n\n\n

What Is an Eye-Catching Subject Line?<\/h2>\n\n

The subject line is the title of your email: the first thing the subscriber sees, along with the sender and the preview text.<\/p>\n\n

An eye-catching subject line isn’t the strangest or the longest one. It’s the one that, in a crowded inbox, gives that person a reason to open your email rather than another.<\/p>\n\n

You’ll find the full definition and its parts in the glossary entry on the email subject line<\/a>.<\/p>\n\n

8 Key Tips for Writing Unique Subject Lines<\/h2>\n\n

1) You Have a Few Seconds to Make an Impact<\/h3>\n\n

Subscribers decide at a glance whether to open, leave it for later or delete. Whatever you write has to be specific, genuine and interesting to the person reading it.<\/p>\n\n

2) Think Short and Direct<\/h3>\n\n

Most emails are read on mobile, where the subject line gets cut off sooner. Put the important part at the start of the sentence.<\/p>\n\n

3) Write Several and Pick One<\/h3>\n\n

Don’t settle for the first one that comes to mind. Write five or six versions and keep the clearest, or test two with an A\/B test.<\/p>\n\n

4) Brevity and Clarity<\/h3>\n\n

Try to keep it between 30 and 50 characters, because many email clients cut off long subject lines.<\/p>\n\n

The subject line should make it clear what the email is about. If readers open it and find something else, they won’t open the next one.<\/p>\n\n

5) Use Keywords and Numbers<\/h3>\n\n

Numbers grab attention and add structure: “5 ideas”, “3 minutes”, “20%”. Keywords sum up the topic of the email at a glance.<\/p>\n\n

6) Personalization and Relevance<\/h3>\n\n

The subscriber’s name helps, but it has been used for many years and can go unnoticed. It works better when you combine it with other subject line styles.<\/p>\n\n

More than the name, personalize the topic: send each group what interests them, with its own subject line.<\/p>\n\n

7) Create Urgency or Curiosity<\/h3>\n\n

A question, a fact or a specific promise sparks curiosity. Urgency works too, as long as it’s real.<\/p>\n\n

If the offer ends on Sunday, say so. If it doesn’t, don’t make it up: readers notice and stop believing you.<\/p>\n\n

8) Make the Most of the Preheader<\/h3>\n\n

The preview text (preheader) is the line that appears next to the subject line in the inbox. Use it to complete the subject line, not to repeat it.<\/p>\n\n

For example: subject line “Your welcome guide is inside” and preheader “5 steps to get started in 10 minutes”.<\/p>\n\n

Tailor Your Unique Subject Lines to Different Subscriber Segments<\/h2>\n\n

The same subject line doesn’t work equally well for everyone. Segmentation<\/a> lets you write a different one for each group.<\/p>\n\n

How Do You Tailor Subject Lines to Each Segment’s Specific Needs and Interests?<\/h3>\n\n
