A TXT record at your domain root, from the same registrar screen you already use.
MX, SPF, DKIM and DMARC come out with the values filled in. No private key is ever copied by hand.
The setup panel watches DNS and ticks each record as it lands. The domain turns on the moment ownership shows up.
An alias, a second verified domain, or a shared team address. Chosen per message, from one picker.
Each one verified and signed on its own, under the same mailbox.
Standard protocols the whole time you are here, not an export button we could take away.
Add the domain, publish what we hand you, and it verifies itself.
