It’s not a selection process but rather whether Disney’s database has you listed as someone who wants to receive promotional emails. Make sure your AP is linked to your
MDE account. Also, in MDE under My Profile, Account Settings, Email Preferences, click on the link to Manage Your Email Subscriptions on Disney’s Privacy Choices website and make sure you’ve checked the relevant Disney Parks & Resorts businesses. The email came to me from Disney Destinations, which is DL Resort and WDW Resort in that list.
