Inbox Optimization

Optimize your subject line and snippet

With Mail Designer 365, you can edit your email’s subject line, as well as the preview “snippet” your recipient will see in their inbox before they open your email.

To edit your email’s subject line, click in the Subject box at the top of the design window and enter your text.

To access the preview and your inbox snippet, click on “Inbox” to open the inbox editor tool. Here you can also enter the subject line for your email, as well as the preview text your recipient will see. You can also view a preview  of how your recipient will see your email messages in Mail on an iPhone and Apple Watch:
