VERSION A

VS.

VERSION B

Very nice experiment.

My gut told me version A is a better winner, as dash works as "call for action". And I was sorta right.

Version A made it by almost 15% over the version B in clicks, however, version B received more open by more than 12%. I don't have a good explanation for that, but that's an interesting thing to come by.
