Email subject line & preheader preview.

See your email in a desktop and mobile inbox. Edit your wording and check what gets cut off.

Write your inbox text

Preheader is the short preview text shown beside or below the subject.

Your text stays in this browser. No uploads, fetching, AI or storage. Refreshing clears it.

Make the first few words count.

This email subject line and preheader preview tool shows how your sender name, subject and preview text fit together in an inbox. Compare a wide desktop row with a narrow mobile layout while you edit. Character counts help you shorten your wording, and cutoff notices show when these sample layouts hide text. Put the main message near the beginning so it stays visible on smaller screens.

Use the preheader to add detail instead of repeating the subject. If it is empty, an email app may pull text from your message body.
