I generated a new address for an exclusive sender. In the list of addresses I saw that it was created on 2006-01-20 05:01. However I never received this email on my G***** Mail account until now. Neither in my inbox nor in the spam section.
I received other emails for other exclusive sender via SG to my G***** Mail account in parallel.
Furthermore I created on of my PM as a trusted sender for the above mentioned SG to check it. It's working.
Any ideas what's going wrong?
