HitSend - Spam Checker for Gmail

See a live spam-risk score as you write in Gmail. HitSend flags what trips spam filters - with one-click fixes. Private, no AI.

Most cold emails don't get ignored. They just never show up - they land in spam, and nobody ever sees them. HitSend checks your email for spam risk while you write it, right inside Gmail. It gives you a score, points out the exact words and links that get you flagged, and fixes them in one click - before you hit send. What it does ? • Shows a live spam score as you type in Gmail • Points out the exact words, links, and formatting that set off spam filters • Fixes flagged wording in one click, or trims it when there's no good swap • Your score goes up as you clean things up Email stays private! This part matters: what you write never leaves your browser. HitSend checks your email right on your own computer. There's no AI, nothing gets uploaded, nothing gets saved, and nothing is ever sent to us or anyone else. Why does it work? Spam filters look for the same stuff over and over - spammy phrases, too many links, risky words, messy formatting. HitSend spots them while you can still fix them, instead of after your email is already buried. Free & Pro Check any email for free and see your top problems. Pro shows you everything and fixes every flag in one click. Write the way you always do. HitSend just makes sure it actually lands in the inbox.
