User designated Email

H, can anyone help me to understand how and if it’s possible to build the following flow - when a user sign in he automatically signed with a designated Email domain as apart of my app domain ie user01@myapp.com - the reason is that I want each user to be able to send attachments via his email directly to his app account from his inbox. Is that possible?

Thanks!

It can’t be automatic. Your app can not send an email using another person’s email domain without some setup. Check out Postmark’s services.
