Sending with Offline RelaySMS Mail (No setup required)

This page documents the Offline RelaySMS Mail flow. Use it when you need to send quickly during a shutdown, without saving platforms first.

This is the fastest way to get started. RelaySMS gives you an anonymous RelaySMS Mail address so you can send messages immediately over SMS.
