Dear Subscriber 3452-ASDF,
We've got some bad news, and some worse news. The worse news is that we're not going to be using you for our next 5,000 user tests. The bad news is that we're going to be using you for our 10,000th user test, but only if you're feeling particularly masochistic.
We're not saying you're not a good subscriber, no, no, no. You're a great subscriber! But our marketing algorithm has deemed you a 0.2% match for our target demographic, which is just not going to cut it. Sorry.
Best regards, The BrilliantBlogs Team
