An email platform for builders

Website inbound.new
Overview

What it is

inbound is the best way to integrate email into your stack we provide the ability to send transactional and marketing emails as well as have webhooks and routing for email receiving (get it? inbound!)

Intent

I need it when

Build AI-powered email agents that reply to customer messages automatically

Inbound preserves full email threading automatically and supports programmatic replies that appear in the correct conversation thread. Combined with AI classification and summarization, developers can build support agents that route and respond to emails intelligently.

Manage multiple email addresses and domains with a single API

Inbound supports unlimited mailboxes per domain and scales to 50–500 domains depending on plan tier. Route specific addresses to dedicated endpoints or use a catch-all webhook, simplifying multi-tenant and multi-domain email workflows.

Use my own domain for sending and receiving emails without vendor lock-in

Inbound lets you add custom domains and configure MX records to receive email at any address. Send from any address on your domain with unlimited mailboxes, DKIM/SPF helpers, and full control over routing and endpoints.

Receive and process incoming emails as structured data in real-time

Inbound delivers incoming emails to your endpoints as JSON webhooks with headers, text, HTML, and attachments parsed automatically. Webhooks fire in under 100ms with exponential backoff retry logic, enabling real-time email automation.

Send transactional emails programmatically from my application

Inbound provides a TypeScript SDK and REST API with Resend-compatible patterns to send transactional emails (receipts, notifications, confirmations) reliably at scale. Developers integrate in minutes without managing mail servers.

Drop

Not a fit when

  • User needs a visual email builder or drag-and-drop interface; Inbound is API-first for developers only
  • User requires SMTP relay without webhooks or programmatic control; Inbound is designed for application integration
  • User needs email marketing features like segmentation, A/B testing, or campaign analytics; Inbound focuses on transactional and inbound processing
  • User operates in a non-technical role without developer resources; setup requires MX record configuration and API integration
  • User needs unlimited email volume at a fixed price; Inbound charges per email tier and add-ons scale costs
