## Why this comes up

The searcher wants to receive and send from a Cloudflare-managed domain and is checking whether SMTP is the missing piece.

## The gap

routing inbound mail and sending outbound mail are related but separate parts of the email experience

## Where DomainSend fits

DomainSend gives the user-facing compose and sent-mail layer that makes the sending setup feel like a normal email app.
