I am sending emails from Azure Webjob (C#) via SendGrid. I don't see any option to add Return-Path in the mail header. Is it possible?
By default, SendGrid controls the Return-Path, and overwrites it to be what they need it to be for bounce management.
If you need it to stay original, you'd have to contact their Support team to disable that setting.
If you just need to get bounce backs, you can set those up using Bounce Forwarding, or get allthedata with Event Webhook.
