Resend does not require you to “create an email address”, “set up a sender identity”, or “add a from-address” before sending. Once a domain is verified in your Resend account, you can send from any email address at that domain.
The email address you send from does not need to exist in another system. However, we recommend using addresses that can receive replies.

​
Common misconceptions

Some platforms require you to create, register, or pre-approve a sending address.
Resend does not. After verifying your domain, you’re free to send from any address @yourdomain, with no extra setup, creation, or configuration of that address.

​
