Campaign external SMPT setting

I have an account on google gsuite. I made configuring the gsuite account in suitecrm and everything ok.
Would you like to set up another SMTP account for campaign submission and can do this?
How do I do that?
I would like to have the gsuite account for communication with the contacts and external SMTP configuration for sending the campaign

You can have several outbound email accounts configured (Admin / Outbound Email Settings).

Then you can have per-user accounts configured on each user’s profile.

I have only one default gsuite email account contact@mydomain.com could use this same email. To set up multiple users.

You can’t repeat the same account as a user account in several users, I think. But try it to see if it complains.

Anyway, you can set an account as a system account and check the options to make it available to users. That way many people can use the account to send. I’m not sure about receiving, though.
