Introduction

PostAgent is a MTA (Mail Transfer Agent). It let's your application programmatically send and receive email utilizing our high performance infrastructure.

In case you're not familiar with the idea, here's an example of how someone might use PostAgent: Say you're an app developer and you want to send users an email automatically when they signup, reset their passwords, and so on, inside your app. You call our API from your backend code with the message you want to send, and we handle sending it for you. Since email infrastructure is so difficult to manage, programmers often choose to outsource it to commercial MTAs like us.

One more example: Imagine you run a marketing firm and you have 15 clients. Each client has a mailing list of 50,000 - 1 million email addresses. You can use our batch API to send millions of marketing emails in seconds with just a few lines of code.

Let us worry about email standards compliance, ESP rate limits, bounces, encryption, MIME encoding, SMTP, and all the other intricacies of email delivery. You focus on your business.

Lastly, we're not just some faceless corporation. We're programmers just like you. If you ever need help or have questions you can chat with our engineers on our Discord server!
