Email Spam Tester Checks Whether Your Message Will Reach the Inbox

Why it surfaced

This is a focused diagnostic tool with unusually transparent mechanics: its report cites relevant RFC sections and Google requirements, compares a classic SpamAssassin score with its own checks, and generates a fix plan whose points are recomputed against the corrected message. It is free during beta, requires no signup, and the disposable test address expires after an hour.

Send an email to a disposable address and receive 39 technical checks covering authentication, blocklists, spam engines, and deliverability requirements.
