We would like to create a custom solution to manage user�s who opt into push notifications (browser notifications). The system would allow us to segment users by the site they opted into, (we operate multiple sites) the ability to syndicate messages across multiple browsers, pass user data in the manages (users name, email, tracking vars, etc.) track delivery, clicks, and impressions. Additionally, it would be nice to split test messages to the user (send message A to 1000, message B to 1000 - send remainder to the winner of that test).
We are currently only interested in US based developers.
