Email inbox preview

Type your sender name, subject line and preheader text and see a live Gmail-style inbox mock — desktop and mobile — so you know exactly what gets truncated before you hit send.

Gmail — mobile inbox

Runs entirely in your browser. Nothing is uploaded.

How it works

STEP 1

Fill in the fields

Enter the From name, subject line and preheader text just as they will appear in your email campaign or newsletter.

STEP 2

Watch the live preview

Two inbox rows update in real time — Gmail desktop (wider) and mobile — showing exactly where text gets cut off with an ellipsis.

STEP 3

Adjust until it looks right

Use the character counters as a guide. Aim for a subject under 60 chars and a preheader under 90 chars to stay visible on most clients.
