Adding form data via e-mail in user-defined format

Adding form data via e-mail in user-defined format

I am reading this documentation,

https://www.zoho.com/creator/help/forms/email-data.html

and I want to add records via e-mail. "Adding form data via e-mail in user-defined format" works fine as described, but is there any way to add more values from the email? Subject, Content, and Attachment are no enough. In our case, I want to store Data/Time, From and To address. It should be possible, but the documentation does not explain further. Any idea?

My goal is to archive all incoming messages in one Gmail account in Zoho Creator.

Thank you.
