As a default, Griddler uses the SendGrid email API, but it can also be used with Cloudmailin, Postmark, or Mandrill. See the SDK documentation for instructions on installing and configuring Griddler.

Today Apsalar announced the release of two new components of its ApScience analytics suite for mobile applications: engagement index & revenue analytics. These new metrics will allow Apsalar clients to gain greater insight into how users are interacting with their application. It will also make it possible for users to be segmented based on the amount they spend in the app. You might be as surprised as I was to learn that this is a competitive space characterized by big data and advertising revenues. Apsalar hits all the bases with SDKs for Android, iOS, and a RESTful API.
Despite all the claims over the years that email is going to go away, it comes as no surprise that email is still and will be the dominant ways that we communicate with each other. People complain that they are not being productive because they end up spending way too much time inside their email application. But what if we turn this equation on its head and instead say that you could actually be more productive while using your email application. PowerInbox strongly believes that and gives developers the tools to accomplish this through its platform and the PowerInbox API.
