Is 'reply to unsubscribe' an acceptable unsubscribe option post Yahoo and Google's new requirements?

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.

A clear, accessible one-click unsubscribe mechanism is crucial for email marketing success and adherence to regulations like CAN-SPAM.

Expert from Email Geeks explains that 'reply to unsubscribe' is growth hacker spammer behavior and should be avoided. If it’s genuine 1:1 mail you don’t need to advertise how you unsubscribe. If it’s bulk mail it’s better to do it properly. If they’re sending low volumes it’s not critical, but if it’s bulk you really want some sort of automation to handle list management, that probably offers an unsub link.
