Focus on your product, we’ll handle your email
Build without limits. Our developer-friendly Email API lets you integrate reliable email sending into any application with just a few lines of code.
An email API that developers actually enjoy using
No marketing speak. We built SendLayer by developers, for developers, with a clean API that makes email integration a breeze instead of a burden.
Lessen the load without sacrificing power
Older XML based APIs require a lot of bandwidth. With a JSON based API, get the results you need using fewer resources.
Speak your language, we will understand it
Our Email API integrates seamlessly with any programming language or framework. Build with what you know and love:
- PHP
- Python
- JavaScript
- Ruby on Rails
- … and more!

Whether you’re building a custom application or using platforms like WordPress or WooCommerce, our API provides the foundation for your email infrastructure.
