Introduction

MailingAPI is a transactional email API built for developers who need reliable email delivery. We handle the infrastructure so you can focus on building your product.

What is transactional email?

Transactional emails are messages triggered by user actions:

• Account emails — registration confirmations, password resets, email verification
• Order notifications — receipts, shipping updates, delivery confirmations
• Alerts — security warnings, usage limits, system notifications
• User actions — comments, mentions, invitations

Unlike marketing emails, transactional emails are expected by the recipient. They have higher open rates (60-80%) and require immediate delivery.

Why MailingAPI?

Built for developers

• Simple REST API — send emails with a single POST request
• Comprehensive SDKs — Python, Node.js, PHP, Ruby, Go, Elixir

High deliverability
