After a provider move
Confirm that mail routing and authentication records are still present after a DNS or hosting change.
WHOIS Lookup / Domain email
Domain and Email Check
Check the DNS records that affect website routing and email authentication. Each result explains what was found and what to check next.
Domain and email check
Check DNS and email settings individually, with evidence and a next step.
DNS checks via Cloudflare, not a security certificate or proof of deliverability. Recursive SPF evaluation, inherited DMARC policies and DKIM signatures are not checked.

Before changing DNS
Record the current results before editing a zone, then compare the provider’s required values carefully.
When mail has problems
Separate a missing DNS record from a mailbox, delivery or application issue before changing settings.
How to read the results
A result can be present, a notice, not found, not checked or unavailable. Presence is evidence of a DNS response, not a guarantee that a website works or email will be delivered.
The check uses Cloudflare’s recursive resolver. SPF is not evaluated recursively, DMARC inheritance is not inferred, and DKIM requires the selector used by your mail provider. It does not connect to websites or mail servers.
