Email tools that answer the question
Small, fast checks for the things that decide whether your mail arrives — authentication records and address quality. No account, no export gate.
DMARC checker
Look up a domain's DMARC record, get every tag parsed and explained, and see what to fix — with guidance specific to Microsoft 365, Google Workspace, and Amazon SES.
Email verifier
Check whether an address is real and deliverable: syntax, live MX lookup, disposable-domain and role-account detection.
Coming soon
SPF checker
Flatten and validate an SPF record, and count lookups against the limit of ten.
DKIM lookup
Fetch a selector's public key and check the record is well-formed.
Email header analyzer
Paste raw headers to trace the delivery path and read the authentication results.
Or let us handle it.
