Definition

What is an email API?

An email API is a programming interface that lets applications send, receive, and track emails programmatically. Instead of building your own email infrastructure, you send HTTP requests to an email API provider who handles delivery, authentication, and tracking.

The problem

What developers face

  • Building email infrastructure from scratch is time-consuming and error-prone.
  • SMTP servers require ongoing maintenance, IP reputation management, and compliance work.
  • Legacy email providers offer poor developer experience with outdated SDKs and documentation.
  • Lack of observability makes it hard to debug delivery issues.
