Opt-outs are happening without users clicking the link

Hi there

Version 7.11.8

I am fielding multiple reports of opt-outs from mailing lists where the recipient never clicked the opt-out link in the email. Is this known behavior? Any clues as to why this might be happening?


I seem to remember that a couple of years ago there was a thread here about some corporate anti-virus software that was trying all the links in each email automatically, to do some sort of security check, and this caused opt-out links.

You’d first need to figure out if this is the case; and it is, a way to mitigate (such as checking referrers).

Here’s what I did to prevent the automatic unsubscribes… Hope it helps!
