How to add preheader text to your email ?

After learning more about email preheaders, there are two ways to add them to your email if you wish to utilize them in your campaign.

Preheader text can be added to emails both with and without coding.

Applying code

You can use code to make the preheader text the first text in the email, which recipients will pull to display in the preheader area of the inbox.

You must add the following code to make this preheader piece invisible to most users in the actual email:

"This is a preheader text."

The code makes it such that it will be nearly impossible for anyone to read your writing because it will render it incomprehensible with a font size of 1, a background color of white, and no opacity.

You must change the “This is preheader text” placeholder text to what you want it to say and then add it to your code.

      Using preheaders in opposition to the subject line is one of the best uses of them. While the subscriber is intrigued by both of them, the preheader only serves to pique interest.

      Unlike the first tactic, which offers important details, this is the opposite. You are omitting the crucial information in this case, but you are also increasing their appeal.

    4. Create urgency to make people feel pressed for time

      People make decisions more often than not based on mental models and psychological biases. The fear of missing out or creating urgency is one such mental model, since people make decisions swiftly and seize possibilities.

    6. Emojis might help you stand out in your inbox

      Emojis can be used in the preview text to make it more noticeable in the recipient’s inbox. Consider how a vibrant emoji will catch someone’s eye in their inbox when they are scrolling through the non-text preview content.

    7. Put a call to action in

      To encourage more recipients to open your email, utilize call-to-actions in the preheader text in addition to the subject line and body.

      You can include a direct call to action, such as “You should read this email to find out what..,” or a more subtle one, such as “shop using (this) to get 10%.”

      To make the best possible preheader call-to-action, adhere to the following guidelines:

      • The call to action should be brief and direct.

      • Make it seem simple to complete.

      • Explain to them why they should respond to the call to action.

      • In order to prevent the call to action from being cut off, make sure to include it within the first few words of the preheader content.
