PowerInbox’s original attempt to save e-mail required that users install PowerInbox alongside their email client. Although users enjoyed the app functionality within their inbox, the bothersome step of installing PowerInbox limited adoption. PowerInbox has removed the install step with the launch of its open API: Connect API.
Context.IO, an e-mail API provider, has announced a "lite" version of its popular Context.IO API. The Context.IO Lite API is not a replacement for the original API. Rather, Context.IO Lite started as a small project to improve Webhook performance. The potential of Lite quickly made itself known, so Context.IO decided to fully develop the Lite version and has now launched a beta version.
