Test Subject Line

When it comes to email, the subject line is key. It's what gets your email opened in the first place, so it's important to make sure it looks good on all devices.

To test how your email subject lines appear on the most popular mobile devices, use the Subject Line Tester from Litmus.

The Subject Line Tester is a free tool that allows you to test how your email subject lines look on more than 30 different devices, including the iPhone, Android, and BlackBerry.

Just enter your subject line into the tool, and it will show you how it will appear on all of the devices.

You can also see how your subject line will appear when it's forwarded to others, and when it's opened in a web browser.

This is a great tool to use to make sure your subject lines look good on all devices, and that they will get your email opened.
