DNS & email tools
Deterministic diagnostics — the same engine the scanner uses, never an AI guess. For the full seven-check picture of a domain, run a scan from the home page.
Paste a record or a domain — count DNS lookups against the 10-lookup limit (nested includes counted recursively) and see exactly which mechanism goes over.
Paste a DMARC record — every tag validated with plain-English findings, plus a deterministic, safely-capped upgrade preview of the next policy step.
Check any DKIM selector, not just the common ones a free scan can guess — see the raw published record, key strength, and revocation status.
No DMARC record yet? Pick a policy, report address, and alignment mode — get a ready-to-publish record, RFC-validated in code, never an AI guess.
Already collecting DMARC aggregate reports? Upload one XML, .gz, or .zip to read it as a table — every sending source, its volume, and SPF/DKIM alignment. Parsed on our servers, never stored.
