Pushtorm.net is a push notification service that allows you to both collect your own base of subscribers and send them an unlimited number of notifications.
Created with affiliate marketers in mind, the service helps you send push notification signup requests to all users who visit your landing page.
Moreover, with this service, you can segment and set up detailed targeting, schedules, and interval-based sending.
You might ask, "Why do I need to collect my base when I can sell push traffic to the ad network?" The answer is simple: because it will be EXCLUSIVELY your subscriber base, which you can convert over and over again to different referrals and verticals using new creatives. According to numerous tests, additional monetization of traffic shows results beyond all expectations: +20-30% to your usual ROI.
And if you feel that you have too much traffic, you can always sell it inside the service.
