We contacted Google support 2 times already. Things we already did: - Setup DKIM records for email authorization - Personalize invitational emails (company name, company logo, inviting person's name). - Use best practises for invitational email templates (they also are similar to Slack) - Setup Google's postmaster (we don't have data yet) - Start handling all company's email from new domain to build it's reputation
Did you guys have similar issues? If so, how did you handle it and how long did it take to be resolved?
