"This only works for some senders right now. We're actively encouraging senders to support auto-unsubscribe — we think 100% should. We won't provide the unsubscribe option on messages from spammers: we can't trust that they'll actually unsubscribe you, and they might even send you more spam. So you'll only see the unsubscribe option for senders that we're pretty sure are not spammers and will actually honor your unsubscribe request. We're being pretty conservative about which senders to trust in the beginning; over time, we hope to offer the ability to unsubscribe from more email."Why do ISPs like Gmail and Hotmail want to utilize this list-unsubscribe functionality?
"So how do the Mailbox providers benefit from the use of list-unsubscribe? Since their users were using the “report spam” button in a way that wasn’t originally intended, businesses would often see inflated complaint rates. This in turn caused false positives with mailbox providers’ spam filters, and flagged opt-in permission-based email as spam. By creating a trusted way for people to unsubscribe, spam complaint rates have been more accurate, and mailbox providers have gotten better at separating spam from graymail. This also explains why both Outllook.com and Gmail use the list-unsubscribe functionality leverage the list-unsubscribe option when for senders with good sending reputations. Neither Google or Microsoft want the list-unsubscribe to be abused by spammers, too."In other words, it helps ISPs better tell good senders apart from spammers. This, in turn, benefits good senders, because making it easier to unsubscribe results in fewer spam complaints, and fewer spam complaints equates to a better chance of getting email reliably delivered to the inbox.
