Based on a real-world ticket:

We are using Mailjet as an SMTP relay for our domain, and the only valid sender address we have set up is our domain sender address "@mydomain.com". Now when emails are soft bounced, one could go to the Mailjet web portal and on the Stats page view which emails were not delivered and more importantly which individual sender sent the email (for example "harry@mydomain.com" taken from the email's From field). Therefore Harry could be informed that his email was not delivered.

We have tried to automate the above process using the Mailjet API, but to do so we need to extract what was the value in the email's original From field. This is not made available anywhere in the Email API, and we also confirmed this through a ticket.

Therefore it would be most helpful if somewhere in the message information, we could get this field, as otherwise, we have to manually download a CSV from the web portal and run a script that does the checking and sending. Having the From info in the API would allow us to completely automate this process.

Thanks for your time and consideration.
