Email API integration for every application

Building email functionality is a surprisingly complex and specialized task. SparkPost’s robust email API makes it simple to embed email into any app or website.

Full-featured email API

With SparkPost’s robust REST email API, your application can take control of every SparkPost feature: manipulating templates, generating messages, sending emails, and reporting performance data.

Simple but flexible SMTP injection

If your app sends email with SMTP, it takes just a few configuration settings to start sending with SparkPost. Nearly every API feature can be invoked via SMTP, so even legacy apps can leverage our robust delivery, analytics, and more.

The world’s most demanding senders rely on SparkPost to deliver billions of emails every day. That’s more than 25% of the world’s non-spam email.

Build powerful apps with real-time data

Real-time webhooks (HTTP callbacks) can trigger actions in your app when an email is opened, clicked-through, or bounced. Create as many different webhooks as your business needs, solving problems as diverse as product workflow and data warehouse ETL.

We speak your language

Use SparkPost with the language of your choice and help your developers hit the ground running. Client libraries for popular languages like Node.js, C#, Python, Java, PHP, Go, and others mean SparkPost is an easy fit for every product.
