Context.IO vs EmailJS: What are the differences?

What is Context.IO? A REST email API that makes it easy and fast to integrate your user's email data in your application. As soon as a mailbox is connected, we create a metadata index of its content starting from the most recent emails which become available from the API within seconds. Context.IO takes care of synching email data for your app so you don't have to build, scale and maintain this infrastructure yourself. Focus on what's unique to your business, we'll manage the technical details of integrating with arcane email server protocols.

What is EmailJS? Send email directly from Javascript. It allows sending email directly from Javascript, with no backend development. The developers create one or more email templates (dynamic content supported) and then trigger an email using our Javascript SDK, specifying the template, and the dynamic parameters for rendering the email.

Context.IO and EmailJS can be primarily classified as "Email API" tools.

• REST Beats IMAP
• Contacts- Recipients and senders with stats like message count and latest sent/received.
