I’ve had several conversations with marketers about email subscription popups like the one new visitors to my site see. Many of the most experienced and results focused are in favor, but there are some “marketing gurus” who are very vocal in their opposition. Never one to leave a debate like this to gut feeling and guesswork, I decided to actually look at my own stats to see what story they had to tell.
These stats are from a single data point, this site. Your site may be different, you should experiment with any tactic like this to see if it works for you, don’t just accept the platitude of your favorite author at face value. I have yet to see any real data to suggest that popups produce any measurable decline in visitor behavior.
