Summary
Gmail and Yahoo enforce unsubscribe requests using a combination of technical requirements (one-click unsubscribe, List-Unsubscribe header), compliance monitoring (assessing user engagement, spam complaints, and unsubscribe rates), and potential penalties (spam filtering, throttling, blocking). Adhering to CAN-SPAM and GDPR regulations is critical, necessitating clear and conspicuous opt-out mechanisms. While honoring unsubscribe requests promptly (within 2 days for Gmail/Yahoo, 10 days for CAN-SPAM) is vital, overall recipient happiness and sender reputation significantly influence deliverability. Making unsubscribing difficult increases spam reports. Consider segmenting lists and using double opt-in to manage consent effectively.

What the experts say
4 expert opinions
Experts highlight that while Gmail and Yahoo monitor unsubscribes and recipient happiness (spam reports), their enforcement capabilities are limited by a lack of visibility into resubscriptions. Managing unsubscribes is a significant deliverability challenge, and making it difficult to unsubscribe increases spam reports. While CAN-SPAM mandates an opt-out mechanism, honoring these requests is only one factor in deliverability; overall engagement and recipient sentiment play crucial roles.

Expert from Word to the Wise explains that one of the biggest deliverability challenges is managing complaints, including spam reports, and unsubscribes, and if you make it too difficult to unsubscribe, people will just hit the spam button. Properly processing unsubscribes is critical for inbox placement. The algorithm change from google is likely the reason you are now seeing the impact of not honoring unsubs.
