Groupon's "Unsubscribe" Link Is at Top of Every Message

Is Groupon's the only one doing this?

Here are some companies that aren't (their link is still at the bottom):

• Ace Hardware
• Adagio Teas
• Amazon
• Amtrak
• Careerbuilder
• CVS
• eBay
• Living Social
• Mint
• Monster
• Real Simple
• Safeway
• Save the Children
• World Market

With email at the core of their business model, Groupon needs to cultivate a list that is as self-selected and engaged as possible. Disinterested list members should be able to opt out easily - lest they generate negative buzz.

Let's see if Living Social and other email-centric businesses follow suit.
