1. Run ads on Facebook, Google content network (and google search if the cpc is not too high).

2. Sign up at forums where your target customers hang out and help people out. Have a link in your signature that points to your website.

Right now, you want to get targeted traffic to your website and capture their email addresses by giving something of value. [free ebook, a discount for early adopters]. Not only will this give you a list of customers for the launch, but the ad copy and the website copy will help you understand what resonates with them [based on conversions] and will prove very useful at your launch.

It is never too early to build an email list.

Thanks dexxter, seems to be the only way I guess. Was kinda hoping to discover a secret ;)

Unfortunately, there are no silver bullets. You have to pedal hard. dexxter's comments are a great place to start.

The big secret is to build an email list :)
