Thank you for posting. I went through the video and completed the steps, but the very last step isn't working (so close!). Instead of the verification email from 'Gmail Team' as shown in the video, I get an email that states:
Delivery Status Notification (Failure)
Address not found
Your message wasn't delivered to "email@MyAppDragDomainThatISetup.com" because the address couldn't be found, or is unavailable to receive email.
"email@MyAppDragDomainThatISetup.com" is just an example...the real address in the message is the one I set up in my AppDrag dashboard per the video instructions.
Any ideas?
