Frequently asked questions
How does the test work?
Generate a disposable address, send us the email you want to test, and in seconds you get a /10 score with a full analysis of authentication, blacklists, content and spam signals.
Is it free?
Yes. No account needed: copy the address, send the email, read the report.
What does the /10 score mean?
We start at 10 and subtract points for each issue found: missing or misaligned SPF/DKIM/DMARC, blacklisted IP, suspicious content and the Rspamd spam-engine score.
Why does my email land in spam?
The most common causes are incomplete authentication (SPF/DKIM/DMARC), missing reverse DNS, a blacklisted IP, malformed HTML or an unbalanced text/image ratio. The report tells you exactly what to fix.
