# Free email preview — test HTML email in real Gmail and Outlook inboxes | Letterhead

Source: https://www.tryletterhead.com/tools/inbox-preview.html

_Free tool_

# See your email in real inboxes.

Paste your email's HTML and we'll send it to our own Gmail and Outlook.com
test inboxes, then photograph it there, on a desktop screen and at phone width (the web inbox in a narrow window,
not the phone apps). You'll also see whether Gmail clipped it in our test inbox.

Email HTML

Up to 102KB. Don't paste anything confidential: the email is sent to our test inboxes and stays there; the screenshots are deleted after a week. One preview a day.

Preview in real inboxes

## In Letterhead, the weight check runs while you write.

The composer weighs every issue and shows what's making it heavy, so you can trim
before Gmail clips it.
