I can see the value of the datapoint. That said, if the automated filter
visits a confirmation link then it would be breaking COI. How are ESPs
discerning between those visits and the ones originated by the recipient
actually clicking on the confirmation link?
It's one of the reasons for the newer
list-unsubscribe-post header in rfc 8058 (as mentioned in the
abstract).
Yes, I'm aware. However, the context of the conversations on this topic
that I remember were centered around making the link "machine
actionable", in the sense that automatic unsubscribe would not need to
jump through hoops but rather, straight unsubscribe. This could keep the
traditional unsubscribe behavior of presenting a form to collect
feedback on the unsubscribe reason.
To me this is very different from plainly GETting a link in an email.
Hopefully this behavior is restricted to images and collateral, not
actual links... but once the line is broken, it's only a matter of time
I guess.
