Hi Danil, I don't believe that this is the case -- at least, I don't see the "magic unsubscribe" button on Mailman3 list messages in my GMail account. GMail doesn't really have the information necessary to auto-unsubscribe from a mailman list because it's not obvious what the subscribed address is for any given list/message -- this is a problem that RFC 8058 solves, and I touch on one example of how this goes wrong up-thread (in February).
I do frequently send more than 5000 messages/day to GMail on busy lists with many subscribers. It's hard to overstate what a huge percentage of the consumer mailbox market that Google has. From my sample, they own more than 60% of subscribed addresses. Looking a the Google Postmaster Tools I see upwards of 99% deliveries TempFailed and I have special-cased retries in my MTA to be every 5 minutes to GMail to try and get vaguely timely message deliveries. Google are always mysterious, but the only big red exclamation mark on their dashboard is lack of one-click unsubscribe. --Jered ----- On Nov 29, 2025, at 3:07 PM, Danil Smirnov via Mailman-users [email protected] wrote: > H Jered, > > On Sat, Nov 29, 2025 at 5:14 PM Jered Floyd <[email protected]> wrote: > >> Having the headers that make Google/Yahoo/Apple/etc ask "Would you like to >> unsubscribe from this?" when they hit the "Junk" button will most likely >> resolve the problem. >> > > As far as I can tell, this already works this way in Gmail even without > 1-click unsubscribe headers.
