Launched the website version with a newsletter.

After discovering Bookbub in the US we decided to launch a website version of our service and to send out a newsletter daily with the best ebooks deals.

What we learned:

If you have and app, ask for the email. This way we could build up our app user base and simultaneously our newsletter reach.
Bring value first -> Ask for money after if you are just starting out. For example, we have highlighted ebooks for free in our newsletter. After the promotion, we reached our to authors and told them about the last spot we had and that we have put them in our email. They were very happy and started using our service after.
