Include preheader text

Using preheader text in email campaigns provides a brief summary of the email content to the recipient before they open the email. This can improve your email open rates and ultimately lead to higher engagement and conversions when used to reinforce the subject line and entice the recipient to take action.

There are two ways to configure preheaders


We recommend you only use one of these two options to specify the preheader of your email

Option 1: In the template of your email

  1. Open your content in the HTML editor. (If you created your content in Simon Mail’s WYSIWYG editor, change the word wysiwyg to template in the URL to access the template’s HTML.)

  2. Locate the opening <body> tag (typically just after the </head> tag):

Where to place the code

The arrow points to where to place the following code

  1. Add this code directly after the open<body>tag:
    <div style="display:none;font-size:1px;color:#333333;line-height:1px;max-height:0px;max-width:0px;opacity:0;overflow:hidden;">
      Add your preheader text here.
  2. Replace Add your preheader text here with the actual preheader text you want to include.
  3. Save your template.
End result

End result, please replace with your preheader text

Option 2: In the configuration of your flow

You may also configure your preheader within the Simon Mail Channel Action configuration.

This field supports dynamic personalization with Jinja, and can be expanded into a full editor using the HTML button on the right.


If you specify the preheader in the flow configuration and in the template of your email, both preheaders will be included (separated by spaces in an attempt to hide the second one from view)
