Has anyone else tried to use Marriott Bonvoy Refer a Friend and been successful? I've submitted 5 different email addresses and none of them have received an invitation. None of the 5: have opted out of email communications, are already a member, have the email in spam, have the email blocked by a firewall, or have their email address entered incorrectly. I contacted Marriott and their response was basically...tough luck, nothing we can do.

I've been using the link on the Marriott website. After entering the requested data I get a page that says "Success! Your invitation will be sent to: [email protected]". Thoughts? Ideas?
