Preheaders, written out.
Illustrative emails and results. Your output will depend on what you enter.

Good to know
Writing preheaders that help.
Subject and preheader should work together
The subject says what the email is about. The preheader adds a reason to open or useful context, without repeating it. For an order update, clarity beats cleverness. For a newsletter, a second specific detail can make it compelling.
Preview text displays differently
Inboxes show different amounts of text and may pull snippets from the email body. Put the most important message first and test in the email apps your readers use. A character count is a guide, not a universal cutoff.
FAQ
Questions, answered.
What is an email preheader?
Short preview text that may appear beside or under the subject line in an inbox.
How long should a preheader be?
No universal display limit. Put the core message first and check previews.
Should preheader text repeat the subject?
Usually not.
Can I leave the preheader blank?
Yes, but the inbox may show the start of the email instead.
Is preheader text visible inside the email?
Depends on your template; it can be visually hidden but still used as preview text.
Does a preheader guarantee more opens?
No.
Email not bringing customers? Let's find out why.
I start by finding the real constraint, then fix that first.
