Unsubscribe requests must be handled promptly and efficiently:
Include a visible and easy-to-use unsubscribe link in every email. Process unsubscribe requests within the time frame required by law (10 days for CAN-SPAM, 10 business days for CASL). Remove unsubscribed users from your email list to avoid sending future emails. Offer options for subscribers to manage their preferences rather than just a blanket unsubscribe option.
