A PRACTICAL GUIDE

How to use the Email Preheader Generator.

Use the preheader to add information that the subject line leaves out. Repeating the subject wastes the small amount of visible inbox space.

Make the workflow fit your task.

Read the subject and preheader as one message, using the second line to add a useful detail or clarify the action. Put the most important wording first and inspect it in the intended email layout.

Decisions and troubleshooting.

Should the preheader duplicate the subject for emphasis?

Use the limited space to add information, such as timing or preparation. Repetition rarely answers an additional reader question.

Why does the inbox show unwanted text after the preheader?

Inspect the actual email markup and client rendering. The copy alone cannot control all preview behavior or fallback text.

Try it with your own source.

Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
