To further optimize the opt-out process, consider the following tips:
Feedback Request: Optionally, ask users why they are unsubscribing. This feedback can provide valuable insights for improving your email strategy. Preference Center: Instead of complete unsubscription, offer a preference center where users can select the types of emails they wish to receive. Re-engagement Campaigns: Periodically run re-engagement campaigns to win back subscribers who may be on the verge of opting out.
