Most popular email clients (including mobile email clients) display a few lines of the message to the recipient before they even open the email. Direct Mail gives you the ability to customize what the recipient sees in this preview area. Here's how to customize the preview text (also known as a "preheader"):
- Go to the Messages tab.
- Click on the message whose preview text you want to edit
- Choose Message > Add Preview Text from the menu bar.
- Enter the preview text. It's best to keep this under 75 characters or so.
Note that the preview text will not appear in the message body (of either the HTML or plain-text versions).
