The Benefits of Confirmed Opt-In vs. Single Opt-in

For the past 25 years I have been preaching the value of confirmed opt-in to everyone that manages an email list. And for the same amount of time I see the look of pain in the eyes of many of the same people when they hear that phrase “confirmed opt-in.” I think the time has come that I write about this issue because there is so much misinformation going around that the idea of confirmed opt-in is getting a bad reputation.
