Nah, those guys are jerks. :P You should really go hang out with the people who wrote RFC 2369, that's where the real prestige came from. Remember how that one guy used to have a website at list-unsubscribe.com bragging about it? I was bummed to find out recently that it's gone; I wanted to link to it in an upcoming blog post about list-unsub functionality. > >List-Unsubscribe: <https://www.example.com/unsub/{token}> > >List-Unsubscribe-Post: List-Unsubscribe=One-Click > > > >I don't know which fools to blame; The client Costco, or their ESP > >WhatCounts.

Checking my traps, I don't see any other mail like that; it does seem to be specific to Costco alone, at least in my own little slice of spamtrap heaven.
