Our take

Diagnoses domain email-deliverability issues by checking SPF, DKIM, DMARC, MX records, and blocklists without requiring an account. It is useful for administrators and support teams doing initial triage, though the remote-only service has no visible adoption signals and its results should not replace provider-side delivery logs.
