Experts and email marketers largely agree that the ideal approach for handling unsubscribes triggered by Gmail's unsubscribe button hinges on meeting user expectations. The prevailing recommendation is to allow users to unsubscribe from specific newsletters without unsubscribing them from all communications. Mailbox providers, like Gmail, respect the List-Unsubscribe header but leave the implementation details to the sender. Compliance is often assessed based on user complaint rates, underscoring the importance of subscriber satisfaction. Providing clear, easy-to-use unsubscribe options, including preference centers, is essential for user experience, compliance with regulations like GDPR and CAN-SPAM, and maintaining a healthy email list and positive sender reputation.
