While it’s true that added friction reduces the likelihood of a desired action, activity in an of itself should never be the sole aspiration of an email marketing strategy. Overall list engagement is a better indicator of program health rather than the size of your lists.
Easy to say if you’re a brand with a sizable database, right? Consider this: companies that win don’t do so because of list size, but rather list engagement, and when it comes to engagement, the double opt-in method holds a clear and obvious advantage.
Some will argue that single opt-in vs. double opt-in is a case of quantity vs. quality, but it’s really a case of list productivity. Single opt-in is the superior subscription process because it maximizes list growth and overall performance by minimizing signup barriers and opportunities for errors.
Using email to its full advantage is all about providing your customers with best possible experience. If they’re happy with the emails they’re receiving, then you’ll reap the benefits (which hopefully includes lots of sales). From the email signup, to the email itself, to the landing page—and everything in between—optimizing for every step of the subscriber experience is key to email marketing success.
