The X to exit out of the pop up is usually much bigger.. we are looking into this now. I apologize for the bad experience!

We also have the ability to target by platform.. so we are turning off the popup now for mobile. Definitely a misstep.

Thanks for the comments everyone... By the way, sorry for the popup issues! We have actually been testing different timing/copy for popups for a blog post titled, "How to Create Popups That Don't Suck". In fact, could we use a screenshot of your responses within the post.. in response to the what not to do section?

On site messaging is a big part of what we provide, so we are always trying to learn, improve, and share those learnings on our blog.
