Maybe people like fresh things?

Here's an A/B test I recently ran on some notification messages. There were two messages, only difference is the word "new" in there.

    A: "You received a message from the admins about your Facebook page."
    B: "You received a new message from the admins about your Facebook page."

A clickthrough 15.64%, B clickthrough 15.95%.

About 1000 samples per group. Not sure if noise.
