To ensure that a subscriber who purchased multiple recalled products receives an email for each product, deduplication should not be selected. This allows Salesforce Marketing Cloud to send multiple emails to the same subscriber based on each unique product in the recall list.
* Why Avoid Deduplication: Deduplication limits each subscriber to a single email per send. Disabling it allows subscribers to receive distinct emails for each product they own.
* Salesforce Documentation Reference: For details, refer to Deduplication Settings.
