About
Inbound is an email infrastructure platform for developers. It receives mail on a user's domain, parses it to JSON, routes addresses to webhook endpoints, and sends replies in the same thread by setting In-Reply-To and References headers. It offers an API and a CLI, aimed in part at giving AI agents their own mailboxes.
At a glance
Inbound receives email for your domain, sends parsed messages to an endpoint and lets your application reply in the same thread. It is worth evaluating when an automated inbox needs both incoming messages and threaded replies.
Good fit
Developers building support or intake workflows that route messages to application code.
Consider something else when
Use a sending-only service if replies are handled elsewhere or your policies prohibit third-party processing of mailbox content.
Start here
Use a test domain and send two synthetic emails to different addresses. Check the webhook routing and confirm the reply appears in the original thread.
Cost and requirements
The publisher lists a paid entry plan starting at $9 per month. You need a domain, DNS setup and an endpoint to handle incoming messages.
Limits to know
Incoming email can carry sensitive data and untrusted instructions. Limit what an agent can do from a message and check how the service stores email and attachments.
