I think what Brian and the testers are missing is that 15k is neither big enough to be impressive nor small enough to be inviting. It’s not a number that works effectively as social proof, and while I can’t test it out myself, I believe, based on evidence for social proof around the web, that DIYthemes would have had much better success with a combined number in the 50k+ range as mentioned above.
Hi Crispian. Yes I have heard of GVO. But I personally use GetResponse. I think all email mnagement systems e.g Aweber, GetResponse, GVO, MailChimp etc allow you to do the same thing, to automate your business by sending a series of pre-loaded emails to create a relationship with your list, provide value to them and of cause promote some products to them so you can make some money. So I'd say choose the one that is appealing to you, learn how to use it and stick with it as long as you want to.

One of the reasons I signed up with WA is because I was having problems filling out the info on Aweber. I couldn't figure out where my affiliate link was supposed to go. I still don't know. I've listened to YouTube tutorials then when I try to do what they say I get confused or have questions and there is no one to ask. One day I'll see the live chat button the next day it's gone. I know it's me but it is so frustrating.
