The removal process is essential for several reasons: 1. Compliance with Laws: Regulations like the CAN-SPAM Act and GDPR mandate that recipients must be able to easily opt-out of receiving emails. 2. Sender Reputation: High unsubscribe rates can negatively impact your sender reputation, causing your emails to be marked as spam. 3. User Experience: Providing an easy and transparent way for users to unsubscribe improves their overall experience with your brand.
