Request the Email Sharing Opt-in List
Epic Games Store users can opt in to receive email notifications regarding a product at time of purchase. In order to obtain the list of opted-in recipients, you must follow the following steps.
Request an email sharing opt-in list
You can request your email sharing opt-in list by contacting Service Delivery: Create a case. In the case creation form, select Type as Product and Issue as Email opt-in delivery request.
Requests typically take up to three days to fulfill, and are delivered to the requestor via encrypted email.
You will receive a full history of opt-ins for the lifetime of your product since collection began. You must track opt-out requests independently from this list, as Epic Games Store will provide a history of all Epic Games Store users who have ever opted in to receive updates about your product since collection began.
