How can I allow users to send emails through my django app but coming from their own gmail account?

Question

I have a django app where users can send emails through the app to contacts that they upload themselves. I use Sendgrid to send the email and the recipient receives an email from a "white-label" address like [email protected]

Now, I would like to implement a system where I can allow users to send emails through our app but that those emails are sent by their own email address. To make it simple, let's just consider "Gmail" and if a user want they can "login with their gmail account" on my app and then send emails from my app that are sent from their account... I know that Gmail has an API and I wonder if I can leverage it to do what I need.

You can definitely send emails using Gmail API methods but keep in mind the below stated in their official documentation:

Note: The Gmail API shouldn't be used to replace IMAP for developing a full-fledged email client. Instead, see IMAP, POP, and SMTP.

As they recommend, you could integrate IMAP/SMTP features in your application so users can authenticate/provide access to their accounts and achieve your goal of having emails sent from their accounts.
