Use this free tool to discover your perfect subject line

Your subject line is the most important factor for deciding whether people open your email. Depending on the email client they’re using, your recipients might see just 25 characters of your subject line.

This Subject Line Checker lets you preview your subject line across a range of email clients and devices instantly. You can also see how your email will appear in the notification box.

Optionally, you can paste in your email’s body content to check the excerpt text that each email client will show, to make your email as inviting to click as possible.
