Free tool
Free email spam checker.
Paste a subject line and body. A real spam filter scores it, against the same threshold we hold campaign email to before it is sent. No signup.
This check runs on every campaign email you send with Fuzegenai.
Each message is scored after personalisation and just before it leaves. One that scores too high is held back. 14 days, no credit card.
How does the spam checker score my email?
Your subject and body are built into a complete email and scored by rspamd, an open-source spam filter that sits in front of many receiving mail servers. It is the same check Fuzegenai runs on every campaign email before it is sent. Lower is better: under 2.0 would be sent, and 2.0 or above would be held back.
What does the checker not cover?
It scores what you paste: the wording, links and structure. It cannot see SPF, DKIM, DMARC or the reputation of your sending domain and IP address, because those depend on a real mailbox sending a real email. A clean result here does not mean a message will reach the inbox.
Is my email stored?
No. The text is scored and discarded. It is not saved, not logged and not sent to analytics.
Is there a limit?
Ten checks an hour from one network. The limit keeps the tool free and available. There is no signup and no email address is asked for.
What pushes a spam score up?
Link shorteners and redirect domains, many links in a short message, heavy HTML wrapped around a couple of lines of text, image-only bodies, shouting capitals and stacked punctuation. Short plain text with one link on your own domain usually scores best.
