I am curious if the Gmail integration will work with subdomains? For example I am sending out confirmation emails when a user submits a form informing them that we have received their submission. At the current pace I am using our main domain, but I am curious if it will allow subdomain email instead, as instead of email@example.com it sends it via firstname.lastname@example.org? I recently tried this but instead it reverted to my main Gmail account I verified with. Is there a step I am missing?
