10 Free Tools To Help You Create The Best Email Subject Lines

Free Tools To Craft The Best Email Subject Lines

Posted in Email Marketing. 4 min read

Your email’s subject line is, simply, the most important thing you’ll write in the entire message.

Why? More people will read your subject line than any of the inside text – and they use that 3-second first impression to determine whether they’ll even click on your mail. You only get one chance, and it could decide the fate of your entire marketing campaign.

The subject is your email’s “headline,” and just like blog posts, that’s where it lives or dies.

With that in mind, it’s no surprise email marketers spend plenty of time looking for ways to make their email subject lines more powerful.

A Good Subject Line is Worth (Many Times) its Weight in Gold

At first, subject lines might look like a troublesome subject. A lot is riding on them!

But think of it this way: There’s no easier and more exciting way to raise your email campaign performance in just a few minutes of work. A single phrase, usually less than 40 characters, can transform your business ... that’s even more power per character than a Twitter tweet.

No matter what methods you use to craft your subjects, one thing is certain ...

You need to analyze your performance to figure out what really works for you!

Make sure your email marketing platform (or your inbound marketing consultant) offers detailed data on delivery rates, open rates, and clickthrough. With this information, you can refine your subject line selections over time by focusing on what resonates with your audience.

Remember: Always be asking what your prospects and customers would be delighted to find in their email. When users realize that your messages always add value to their lives, they are that much more likely to open them, regardless of subject.
