Confirmed Opt-in improves campaign results! Check out these stats now!
About three months ago, we were trying to convince you that confirmed opt-in option is much more effective than the unconfirmed opt-in when adding qualified subscribers to your lists. We gave you several important reasons to validate our point of view.
If the last blog post didn’t convince you, we hope the results of our latest analysis will help you understand how well confirmed opt-in works for real-life GetResponse customers, and put all serious arguments to rest.
Now, onto the study: we analyzed over 700M messages sent from GetResponse Pro accounts between August 1st and November 1st 2009, and compared certain “success” factors for confirmed opt-in and unconfirmed opt-in users. We thought we’d find improvements with confirmed opt-in, but the results amazed even us!
