UPDATE (8:05 pm ET): Google is reporting the issues with Gmail have been resolved. However, some systems will not return bounced mail for a period of several hours.

ORIGINAL POST: Google is, again, reporting issues with their Gmail email services this evening, Tuesday, 12/15/20. This outage may lead to some email being sent to Gmail contacts to be returned or “bounced”. Returns may extend past the “fix” status of Gmail as some systems will not return bounced mail for a period of several hours.

If you have received a returned message from a Gmail contact your email has not been delivered and it is best to attempt a resend after the issues are reported as resolved.
