Summary
Experts, marketers, and documentation from various sources agree that subscription-based emails require a list-unsubscribe option, often with one-click functionality, to comply with Gmail and Yahoo's new sending requirements. These requirements aim to reduce spam complaints, improve sender reputation, and enhance deliverability. The need for unsubscribe options typically applies to emails that are not transactional. Gmail’s new rules judge sender reputation based on spam complaints; senders need to give people an easy way to unsubscribe. The RFC 2369 standard provides guidance on implementing list-unsubscribe headers. High-volume senders (over 5,000 emails per day to Gmail) are specifically targeted by Google's one-click unsubscribe mandate. If the sender fails to include unsubscribe functionality it will likely cause deliverability issues.
