We used Kickofflabs to get a quick solution. We chose them because they also include a mini "referral program" so after someone enters an email, they can spread the word and get a discount or even free premium with enough referrals.

To get traffic we used all sorts of sources, like Twitter, Reddit, Linkedin. No spam, and we made sure to follow all the rules (mention it in proper context etc.) We also got featured on Betalst.
