Kickstarter helped a ton, promotion of the campaign helped me get to 800 email subscribers by launch day. Not huge, but not tiny either. Reddit (a mentioned in the post) was also almost as big as product hunt.
800 is pretty good to have out of the starting gate. The number one hardest thing I've found in self-publishing is to build a good following or email list. I'm around 500 subscribers at this point. That's after about a year of working to build the list. Kickstarter is a good idea I hadn't really considered. Thanks again. oh and if you want to check out my books, head over to mattlambert.ca
Yeah, Kickstarter is a LOT of work but it's great at both building up an email list as well as getting an "advance" for your work before it's released (of course, only if the KS is successful.)
