Full Email Delivery Reporting Features

Access to metrics is valuable to all businesses and we provide reports in the control panel of each account. Our system can transfer reporting into Google analytics so that exact traffic can be recorded from each individual type of email.

With integration into Google Analytics you’ll know exactly how effective your messages are. Couple that with our A/B testing and you can see which welcome message is more effective!

Ease of Integration

The API is easily integrated into PHP, Python, and Ruby, and the Triggermail website provides access to all of the settings and template editing. Our proprietary email software is built in Java and has been built to easily scale on demand and send messages in under 0.5 seconds.

The Triggermail API is a simple REST-based service. You can send email templates, check on the status of previous sends, and update templates remotely. We return data in your choice of JSON and serialized PHP.

We offer client libraries to easily integrate your website without knowing the intricacies of the API. We currently offer API client library code for PHP5, Ruby and Python.

Global Infrastructure

Where Triggermail really shines is our fully hosted email infrastructure, delivering real time instant delivery status reporting for all your email campaigns and automated site emails. You’ll never have to worry about maintaining your own email servers for high volume email delivery again.

We have 2 redundant systems in both London and New York running a series of small clusters, which not only improves delivery efficiencies but allows us a dynamic failover in the event of a failure in either system.
