Spam Word Checker
Paste your subject line and body. We highlight the spam trigger words dragging you toward the junk folder, weighted by where they appear.
Runs in your browser. Nothing is sent or stored.
Heads up: modern spam filters weigh sender reputation and authentication far more than words. Clean copy helps, but infrastructure wins.
Built by the Mail2Lead team
Words are maybe a tenth of deliverability. The rest is domains, warmup, and sender reputation. We build that for a living.
