Domain Validation Guide

Prove you control the domain with email, DNS, or HTTP validation.

Email validation

Approve a message sent to an allowed administrative address such as admin@, administrator@, hostmaster@, postmaster@, or webmaster@.

DNS validation

Create the TXT record shown in your dashboard, then wait for DNS propagation and status polling.

HTTP validation

Upload the provided file to the required .well-known path and keep it available until validation is complete.
