How I built a 55,000 person email list in 2 weeks via Twitter & how you can use the same concept to build YOUR list

Posted by Brad Callen | March 24th, 2009

Hey guys, I sent out an email about this a couple weeks ago and have gotten some good feedback from it, so wanted to post here to quickly go over the process of what I accidentally did to build a very large email list in a short period of time.

1. I created, which is a cool Firefox addon for keyword research. The overall process/flow of the software itself is very viral. (i.e. there is a big incentive for others to tell others about it, other than just because it’s good (which should always be a given if you create and sell anything)

2. I created a short demo video of me explaining how the software worked and what it does.

3. I posted a link to the video on my Twitter page ( The video was nothing special. It was just me explaining the software and talking about how excited I was about releasing it to the public. It was 100% complete, but I was bored while my programmers were putting the finishing touches on it, so I had time to make a video showing how it worked. I made sure to mention that it wasn’t quite ready/complete, but would be soon.


– At this point, I’ve never mentioned the URL (web address) to where my Twitter followers could get the software… Basically because it wasn’t quite finished yet. I did, however, mention the name of the software.

– I only had about 2,000 followers at the time
