Your best cold email is
worthless in spam.
HitSend checks every email before you hit send, flags exactly what trips spam filters, and shows you the one-click fix. Land in the inbox - not the folder no one opens.
Watching you write…
The quiet killer
You didn't get ignored. You never got seen.
One spammy word in the subject. Three links in a short email. A sneaky ALL-CAPS. That's all it takes for a filter to bury your outreach - and you'll blame your copy, your list, or your luck.

warnings you get when it happens. No bounce, no notice. Just silence.
is all it takes to catch the triggers before you send to your whole list.
How it works
Three steps. No dashboards to learn.
It feels like spell-check - except instead of typos, it catches the things that send you to spam.
Write like you always do
Draft your cold email in Gmail. HitSend reads along quietly in the background - no new tab, no copy-paste, no send-a-test-and-wait.
See exactly what's risky
The moment a phrase trips a spam filter, HitSend flags it - with the reason and the exact point cost. Trigger words, ALL-CAPS, too many links, a missing unsubscribe, and more.
Fix it and hit send
One click rewrites the flagged phrase to safer wording - or trims it when there's no clean swap - and your score slides toward green. Then hit send, knowing it'll actually land.
The score
A number you can actually read.
Every email gets a 0-100 spam-risk score. It isn't a percentage - it's a points system. Each risk we spot (a spam word, a shortened link, a missing unsubscribe) adds a few points, weighted by how much filters actually care. Fewer points → lower score → more likely to land in the inbox.
So the rule is simple: the lower, the better.
Clean. Nothing worth worrying about - hit send.
A few things could tip this into spam. Worth a quick look.
Likely to be filtered. Fix the flagged items before you send.
