Can you write 10 subject lines in 2 minutes? And not just any subject lines – high-converting ones that are different enough from each other that they’d give you good results from a split test? 

We invite you to take the challenge! On the next screen, start the clock and write 10 awesome subject lines. Got your quill and ink handy? LET’S GO!
