Filters score content, reputation, authentication, and engagement together. Cleaning cheap spam signals will not fix a burned domain — but leaving them in makes recovery slower. Use this checker before you send; pair it with the Domain Health Checker and Subject Line Tester.

Trigger phrases, CAPS, punctuation, link clutter
Identity
SPF / DKIM / DMARC and dedicated sending domains

List quality, reply rates, complaint & bounce rates
Rules-based and transparent — not a black-box “AI spam score.” Each category maps to patterns filters and humans both distrust on cold first-touch.
Words and phrases filters associate with bulk marketing and scams — “free,” “act now,” “click here,” “guaranteed.” On cold email they are weighted harder because you are not on a permission list.
Dollar hype, “cash bonus,” and “lowest price” patterns look like affiliate spam. Lead with a business outcome in plain language instead of sounding like a clearance email.
“Last chance,” “expires soon,” and stacked deadlines train filters and buyers to ignore you. Cold first-touch should feel calm and specific — not countdown-clock marketing.
ALL CAPS runs and !!! stacks are classic spam signals. Sentence case with one period (or a question mark for reply-bait) is the cold default.
Too many links in a first touch looks like a blast. Prefer one clear CTA — calendar link or a single resource — and put secondary links after a reply thread starts.
