Send Emails

Transactional email via a single POST request. No SMTP, no templates, no complexity.

Receive Emails

Route incoming emails to your app via webhook. Structured JSON payloads, instantly.

Email Addresses

Create addresses like support@yourdomain.com. Use them for sending, receiving, or both.

Custom Domains

Connect your domain with automated DNS verification. Full control over sender identity.

Webhook Routing

Forward inbound emails to any endpoint. Build support systems, notifications, or automations.

Usage & Logs

Track every email sent and received. Real-time delivery status, timestamps, and errors.

Why BackLabs

More than just a sending API

Most email APIs only handle sending. BackLabs gives you the full stack.

Full email infrastructure

Send, receive, and route — not just one direction. One API for your entire email layer.

Programmable addresses

Create email addresses on the fly. Each one becomes a programmable endpoint for your app.

Built for SaaS developers

Designed for developers building products. Not for marketers running campaigns.

Clean API + dashboard

Simple REST API with a modern dashboard. Set up in minutes, not days.

Domain verification

Automated DNS verification flow. Connect your domain and start sending with your own identity.

Fast setup

From signup to sending your first email in under 2 minutes. No configuration headaches.

How it works

Three steps to email infrastructure

01

Connect your domain

Add your domain and verify DNS records. BackLabs handles the provider configuration automatically.

02

Create email addresses

Create addresses like hello@yourdomain.com. Optionally set up webhook URLs for receiving inbound mail.

03

Send & receive emails

Use the API to send transactional email. Inbound emails are forwarded to your webhook as structured JSON.
