From Direct Magazine comes Microsoft's new announcement of their adding a new "unsubscribe" link inside their email interfaces (like Windows Live Mail and Hotmail).
Why this is huge...
Currently, most ISP's - (MSN, Hotmail, AOL, Yahoo! and others) all include some variation of a "Report as Spam" button within their interfaces. Many recievers of your email tend to click on the "Spam" button instead of the unsubscribe link within the email (which you'd rather they do). Why? Some unscrupulous spammers look at who is clicking on the unsubscribe link as an "active" recipient and ignore the unsubscribe request.
The problem with the existing "Report as Spam" button
The more your recipients click on the "Report as Spam" button the less reputable you/your sender become in the eyes of the ISP. This differentiation could reduce the number of spam complaints you get in your email marketing campaigns, by clearly delineating an unsubscribe that is controlled by the ISP from a spam complaint.
This product is in beta so we'll keep you up-to-date on it's launch. E-mailers call for AOL, Yahoo!, and all others to follow Microsoft’s lead.
