In my experience, conversation rates were ~6% from a pop up timed to land when you were nearly done with the article (though on short articles, it was similar to what is described—I don’t have data on those two broken out). Subscribers stuck pretty well, something like 40% kept opening emails. For my relatively small newsletter, churn was extremely low. They’re basically warm leads if they make it to the end of an article, and email is extremely sticky.

Email pop ups are a very effective short term newsletter growth tool.
