How to add return header header using SendGrid

Question

I am sending letters from Azure Webjob (C #) via SendGrid. I see no way to add Return-Path to the mail header. Is it possible?

Answer 1

By default, SendGrid manages the reverse loop and overwrites it as what they need to control the rollback.

If you need to keep it original, you need to contact support to disable this option.

If you just need to get bounces back, you can set them using Bounce Forwarding or get allthedata with the Webhook Event .
