How it works

Three API calls to a working inbox.

01

Create an inbox

POST /v1/mail/inboxes — returns a unique address at inbox.fairmail.ai or your own domain.

02

Receive via webhook

Inbound emails fire message.received events to your webhook URL. Clean reply extracted via Talon.

03

Reply programmatically

POST /v1/mail/messages — send from the inbox. Threading handled automatically via headers.

Capabilities
Per-inbox API keys Scope a key to a single inbox. Your agent only sees its own messages.
Thread derivation Automatic threading from In-Reply-To and References headers.
Reply extraction Talon strips quoted history and signatures. Get the last reply, clean.
BYO domain Use your own domain or <random>@inbox.fairmail.ai with zero setup.
Shared infrastructure Same domains, contacts, rules, and billing as every other FairMail surface.

Give your agent an inbox.

Create a programmatic inbox in one API call. Pay per message, not per month.
