Learn how to add custom preview text to your HTML email.
Preview text (also referred to as preheader text) is the bit of text that is shown below or next to the subject line in the inbox that gives insight into the contents of the email. By default, email clients show the first 40-180 characters of text content in the email.
If you want your preview text to be a brief custom description of what's in your email, you can specify preview text in Tabular via the Checklist.
We add the preview text to your HTML email as the first textual content but visually hide it, so recipients who view your email won't see the text in the email design, only in the preview text area of the inbox.
