Notify your users simply and beautifully

Your application calls this:

#           |---------- tattler API ----------| |--- app and event name ---|
curl -X POST http://127.0.0.1:11503/notification/trafficchecker/abuse_warning/?user=123

... and tattler sends these:

Example of a notification SMS sent with tattler

Tattler handles the chores.
You design communication across your customer journey.

Tattler takes away the myriad small complexities of sending notifications:

Templates
  • Load all defined templates for your event over email, SMS etc.
  • Expand them with a powerful language including loops, conditionals, pluralization and more.
  • Assemble multi-part MIME emails with your HTML content and plain text as a fall back.
Data
  • Fetch email, mobile number etc of your recipient, so your code only handles events and user IDs.
  • Fetch variables to expand your templates from your DB, so your applications don't have to.
  • Allow easy integration via plug-ins, including reusable code samples for you to fill out and deploy.
Control
  • Collect all notifications from every system and to every vector into one place.
  • Provide a single point of exit, for simpler configuration and security.
  • Allow triggering systems to share or separate their branding.
