To implement immediate revocation, follow these steps:
Unsubscribe Link: Ensure every email contains a clearly visible unsubscribe link. Automation: Use email marketing software that allows for automated removal of unsubscribers from your list. Confirmation: Send a confirmation email to the user, acknowledging their request to unsubscribe. Feedback: Optionally, provide a feedback form to understand the reason behind the unsubscription, which can help improve future campaigns.
