Email Spam Checker
Paste an email. We flag spam-trigger words, all-caps abuse, link risks, and missing unsubscribe — instantly, no AI required.
How this works
Modern spam filters are layered: word-level pattern matching is the cheap first pass, but the bigger signals are sender reputation, authentication (SPF/DKIM/DMARC), and engagement history. We can't see those. What we can do is keep your copy from triggering the cheap filter in the first place.
This checker runs entirely in the browser-adjacent layer — no AI call, no waiting. We scan for ~400 known spam-trigger words and phrases, count exclamation marks and all-caps ratios, audit links for shorteners and suspicious TLDs, and confirm the email has an unsubscribe path (CAN-SPAM and GDPR both require it for commercial sends).
Risk score 0–30 is generally safe. 30–60 means you're flirting with filters and should rewrite the worst offenders. 60+ is a good way to land in promotions or worse.
The hard truth: even a perfect-scoring email can land in spam if your domain is new or your previous sends got marked as junk. This tool is necessary, not sufficient.
