HTML and CSS Templates

Having your email templates inside of your app means that any changes made to any part of the email will require a re-deploy of the app. This can be time consuming and is prone to errors.

With PostageApp, you can host your templates with us and write them in plain HTML and CSS and make any changes you need to without having to re-deploy anything. When we send your emails, we automatically flatten your code into email safe markup!

Personalize for Every User

You can use message variables inside of your templates to easily personalize emails for users and give them customized content. Greet them by name and send them content relevant only to them, making your emails more valuable to your users and improving deliverability!

Engagement Analytics

Email provides a great window into user engagement. Detailed reporting of email activity tells you the story of what has happened to your emails, and those stories provide insights into your business.

We provide information on classic email metrics - opens, clicks, and inbox placement rate (IPR), as well as more subtle - if your users are providing fake or throwaway emails. Never be left in the dark again.

Clean and Simple Integration

The PostageApp Email API is a JSON-based API that you can utilize by sending an HTTP POST request. It’s clean, simple, and made by developers for developers.

In addition, we have quite a few plugins for various languages and frameworks - from PHP to Rails and node.js - already available, to get you up and running even quicker.
