Gmail Clipping Predictor
Estimate your email's HTML size and check whether Gmail will clip it. Emails over 102KB are cut off with a "[Message clipped]" link — and clicks fall.

What Causes Gmail Clipping
Gmail clips any email whose HTML exceeds 102KB. The largest offenders are base64-encoded inline images, which expand a small JPG into kilobytes of text. A single full-width hero image at 100KB+ source can push a whole email over the limit by itself.
When an email is clipped, everything after the cut — often your secondary CTAs and footer — disappears behind a link that most recipients never click. If your primary conversion action sits below the fold, clipping directly costs you conversions.

How to Stay Under 102KB
Host images externally instead of inlining them, compress and resize images before adding them, remove commented-out code and unused styles, and keep your email structure clean. Every email client has its own limits — Gmail clips at 102KB, while Apple Mail and Outlook are more forgiving — so optimise for the strictest.
A practical target is 60-80KB, which leaves room for ESP tracking pixels and dynamic personalisation tags that expand at send time. If your email is over 102KB, cut images first: they typically account for 70%+ of the total size.
