tattler 1.1.0

A client-server notification system for HTML emails, sms and more.

Tattler – enterprise notification system

Overview

Tattler is an enterprise notification system. It allows you to send notifications from any application like this:

curl -X POST 'http://127.0.0.1:11503/notification/mywebapp/password_changed/?user=123'

Tattler then sends a beautiful, branded notification to the user across email and/or SMS.

Tattler does the heavy lifting of notifications for you:

• Personalize notifications to each user with templates.

• Compose compatible HTML emails with text fallback.

• Look up user contacts to deliver email or SMS.

• Tag notifications with unique IDs to aid Support teams.

… so you can focus on your customer journey and brand.

Introducing Tattler usually simplifies a lot of code, and consolidates communication to your users making it easier to manage and improve.

Your product managers will love having a trivial process to organize communication across the customer journey, and the resulting visibility.

Your template designers will love the flexibility and ability to care of user-visible content without distractions.

Your devs will love the massive simplification in their code for just triggering notifications with one HTTP POST request and without having to seek all ancillary data.

Your support team will love having access to all notifications sent to users, and its trivial root-cause analysis across many systems.

Your sys admins will love having one single point of exit for user notifications, and the ability to trigger notifications across different containers or even servers.

Advanced features

Additionally, Tattler supports some advanced deployment scenarios:

• Deploy containerized components, that only communicate via TCP.

• Deliver notifications from multiple components, even if on different servers (billing, web application, batch processes etc)

• Tokenize contact information, so components only deal with user IDs, and Tattler expands the associated user information.

• Collect additional variables about a user in one place (free/paid, resources used, …), and make it available to notifications from all subsystems.

• Insulate notification system from other systems.

• Restrict access to your users’ contact data in your database to Tattler only, preventing data leaks in case of a hack.
