Sorry, GET requests aren’t idempotent. At the minimum they create log entries. So you can DDoS servers by filling their logs with “idempotent” GETs. UX is important, and I think saying “suck it users, I’m going to use GET the way I think is write” is not a positive way of thinking about it. I think the problem is just the mechanics of POST not being allowed in an email, so if there’s a way to POST from just clicking on a link I think we should use it. But there’s not, so having a GET that triggers something is the least bad thing. I like it better than javascript and forms in email. And better than autosubmitting, hidden forms on load.
