Our take

Offers free email-domain and message checks, including blacklist lookups, spoofing/BEC grading, redirect tracing, spam testing, and WHOIS. It is for deliverability, security, and support workflows that need quick diagnostics around email reputation and routing. The listing is practical but broad, so users should confirm result sources, rate limits, and whether outputs are explainable enough for security decisions.
