Sender email addresses
You send from any address on a verified domain. Nothing to provision.
You do not create sender addresses. Verify a sending domain, then send from any address on it.
How it works
We check the domain in from, not the part before the @. Once mail.example.com verifies, hello@mail.example.com, billing@mail.example.com, and any other address on that domain can send. There is no sender identity or mailbox to set up, and you do not need an inbox to send.
The domain must match exactly. Verifying example.com does not verify mail.example.com.
If you leave from out of a REST send, we use hello@ your first verified domain. See Choose a send path.
Receiving replies
An inbox is for receiving mail, and it is separate from sending. If you want replies to reach you, create an inbox and set it as reply_to, or receive on the sending domain. See Receiving emails.
