Return-Path
The address where bounces and delivery notices are sent, also called the envelope sender.

In practice
SPF checks the domain in the Return-Path. Using your own domain there, instead of the platform’s, helps your messages align for DMARC.
Verification and sending
Bounces arrive at the Return-Path. Process them so bad addresses are suppressed.
