I got an address for claiming missing stays - firstname.lastname@example.org, but it does not work. Please confirm the correct address.
I'm not sure this will help, but Marriott is spelled with 2 r's. Your address above shows only 1 r .
painedplatinum is correct. You need to have two "r's" in Marriott, as well as an "s" at the end of "reward". So the proper address is: email@example.com
You can also contact one of the customer service offices with the information on this page: https://www.marriott.com/suggest/default.mi
