Email DNS and privacy checks

Email Privacy Tools

Practical DNS and email inspection tools for debugging delivery, authentication, and temporary email workflows.

Check the mail exchange records for any domain and see which servers receive its email.

Find and review the SPF TXT record that tells receivers which servers may send mail for a domain.

Check a domain's DMARC TXT record and review its policy, reporting, and alignment settings.

Lookup a DKIM selector and domain to confirm whether the public signing key is published in DNS.

Paste raw email headers to inspect routing hops, authentication results, message IDs, and sender details locally in your browser.
