The email that such communications are supposed to be coming to is the one at the very bottom of the “my ownership” tab, under “point of contact.” There are also email addresses for each owner with a login that appear under “account settings” or “view or edit account” on the main dashboard - these can be edited by the user but they don’t affect where the critical emails are sent. I know some people have indicated that they’re not receiving emails even at the point of contact address, and obviously I don’t know why not, but that’s the only address that matters.
I’ll take this opportunity to once again assert that Wyndham should be sending these emails to every owner that has an individual login and not just one point of contact per account. If each owner is equally responsible for the account and equally able to book reservations, they should all be sent these messages that could affect any reservation they make. It’s ridiculous.
