I'm sorry about that. There was a Google outage recently where emails failed to deliver, and we stopped sending to avoid additional conflict. If your email was on this list of affected address', then please reach Customer Support to check the LMI Bounce List to clear it: https://support.goto.com/meeting/help/how-do-i-contact-gotomeeting-customer-support-g2m090151
I created a new user in our Admin center but she is not receiving her welcome mail from GoToMeeting.
Apparently her mailbox didn't exist at the moment of creating the user and I saw on this community that her e-mail address might be on the blocklist.
Really hope that you can help me out!
