Add a preheader to an email

Last update: April 3, 2025

A preheader is a short text that follows the subject line when viewing an email from any major email client.

In many cases, it provides a short summary of the content, and is typically one sentence long.

NOTE

Preheaders are not supported by all email clients. When not supported, the preheader does not display.

To define the email preheader, follow the steps below.

From the Email Designer, add at least a Structure component to start designing your email.
Click the Navigation tree icon from the left pane, and select Body.
From the Settings tab, enter some text for your preheader.
To further personalize it, click the Add personalization icon to the left of the Preheader field.
From the Edit Personalization window, add personalization fields, expression fragments, and conditional content using the dedicated entries on the left.
Click Confirm.
