I'm working with a client whose email was working, but she stopped receiving emails after her domain ownership information was updated. She still can send emails. Her senders aren't receiving any sort of "failure to send" messages; the emails simply don't show up in my client's mailbox. I'd appreciate any advice!
Updating domain ownership information should not affect your client's email function. Without the email address or domain name it's difficult to pin point what the issue might be. I suggest giving our support team a call to look into this.
