For this video, I did a unique test were I exported un-verified leads from my Aweber account into another service that allows list import. Normally I would NOT recommend you do this. It is a borderline tactic at best, but I wanted to prove a point... and technically speaking, these people would be on my list if I was using single opt-in.
I sent those users some valuable content in an attempt to bring them back into the fold. It was an absolute failure. I put together a free video tutorial on this, and all of my other reasons for using double opt-in. You can watch it here:

Please forgive the blatant link... I don't sell or promote any products or services on my website. I would have preferred to embed YouTube for something like this, but I just launched the YouTube account for this website (so it still has 10 minute limits until I can apply for partner status).
