Recently, several of my Clients are reporting that their AEM newsletter recipients are being listed as having to Opt-Out, when they state that they did NOT click on the Opt-Out link at the bottom of the newsletter.
One of my clients, who have an SPF in place, had more than 1/2 of their own employees listed as Opting Out.
This client did significant testing working with their ISP provider. It turns out that their Anti-Virus flagged the single-click Opt-Out link as the culprit. If AEM would modify the Opt-Out to be a double-confirmation, I am thinking that all of us AEM Users would find that our clients, and our Clients' Clients, would experience less false Opt-Outs.
Also, if there was an Opt-In link on the Act! website that recipients could go to for Opt-In, it would be far easier than the current process.
