Hi there,
I hope this message finds you well. I am reaching out because I recently sent an invitation to one of my engineers, but it seems he has not received it yet. Despite checking various folders such as spam, junk, and webmail, I have been unable to locate the invitation.
I apologize for any inconvenience this may have caused and I would appreciate any suggestions or assistance you may have in resolving this issue. Thank you for your time and attention.
