Email · Auth
Check a domain's email authentication: SPF record and its all-mechanism and lookup count, DMARC policy, DKIM at common selectors, MX hosts and mail provider, and BIMI, with plain findings and an A-F grade. Answers whether mail from the domain can be spoofed and whether it is set up to reach inboxes. Errors return 4xx/5xx JSON and aren't charged.
