Subject: Following up on our partnership
Hi, I wanted to follow up on my previous email regarding our advertising packages. We offer great visibility for your brand across digital and print placements.
Modern spam filters use ML models that read your email like a human would - judging intent, flow, and context. One wrong pattern sinks the whole message.
Even polite, professional language gets flagged when the overall tone reads as persuasion or advertising intent.
Repeated subject lines, follow-up sequences, and formulaic sign-offs match mass-mail patterns that filters are trained on.
Semantic models score the meaning of your message - not individual words. A perfectly worded cold email still looks like spam.
Hamcut runs the same semantic ML scoring that inbox filters use - and rewrites to fix tone, structure, and pattern, not just swap words.
Drop in subject + body. Plain text, HTML or raw copy - all supported.
Hamcut returns a HAM / BORDERLINE / SPAM verdict with tone, structure and intent analysis.

Real results from teams using Hamcut in production.
“Our cold email open rates jumped 34% after we started running every sequence through Hamcut. It catches stuff no human reviewer would notice - the sentence structure, the flow, the tone.”

“I tested it on an email I'd sent 200 times with mediocre results. Hamcut flagged the intro paragraph as sounding like a sales pitch - rewrote it to feel personal. Reply rate doubled.”
