Bypassing using OAuth for GSuite Mails

Is there a way for me to bypass the need to use OAuth for me to send out emails using the G-Suite platform in my application

I am still able to send out using the Microsoft 365 platform but some of my clients will not move to 365 and prefer G-Suite

You can use a service account. You will need to have the admin of the domain configure domain wide delegation to an account on the domain.

Once delegation is configured you can then use your code to impersonate a user on the domain and send emails on their behalf. This is what i normally do with sa a system designed for sending email conversation mails. When a user creates a new account the system could send an email conformation email. On behalf of say [email protected]

Your issue is going to be with the fact that your clients are the ones who own the domain so your going to have to get the google workspace admin for your client to set this up for you.

The other option would be to use standard oauth2 and authorize a user on the domain and send emails on their behalf.

The issue with that is going to be your application will need to be verified with one of the highest protected scopes. Your app will need to go though a security audit before it is verified. Last I checked that audit will cost you $15k-75k
