Summary
The overwhelming consensus from experts, email marketers, and official documentation is that 'reply to unsubscribe' is not an acceptable method under Yahoo and Google's new requirements for 2024. Google specifically mandates the 8058 unsubscribe method and one-click unsubscribe processed within two days, while Yahoo emphasizes the use of List-Unsubscribe headers. This shift is driven by the need for standardized, user-friendly opt-out processes that prevent spam complaints and improve deliverability. Using 'reply-to' is viewed as spammy and non-compliant, impacting sender reputation. A clear, accessible one-click unsubscribe mechanism is crucial for email marketing success and adherence to regulations like CAN-SPAM.
