Interesting article here from MultiChannel Merchant about how more and more people are clicking that "This is spam" button in their email applications, instead of clicking the "unsubscribe me" link (even with emails that they’ve actually opted in for). No big surprise, right? We’ve talked about this in the past, and suggested that people start placing their opt-out links at the top of the message (instead of buried at the bottom). People get waaaay too much email, so that "junk button" is extremely convenient. And raise your hand if you’ve memorized the keyboard shortcut for "mark this as junk" in your email program ("J" in Mozilla Thunderbird, and "Command-shift-J" in AppleMail).
