# Kerabie Mail

> Kerabie Mail is an email hosting and mailbox API platform: connect a domain, a standard IMAP account, or a free @kerabie.email address, then send, receive, and manage mail through a REST API. Built for both human developers and AI coding agents to integrate quickly — one send endpoint, typed errors, per-plan rate limits, and webhooks for delivery events.

## API documentation

- [API reference](https://kerabie.email/api-docs): authentication (API keys, every plan tier including Free), sending email, templates, inbox, contacts, calendar, labels, and usage endpoints.
- [Webhooks](https://kerabie.email/api-docs/webhooks): subscribe to delivery, bounce, and inbound-mail events.
- [Partner API](https://kerabie.email/api-docs/partner): for platforms provisioning mailboxes on behalf of their own users.

## Sending mail

- `POST /mail/send` accepts a single API request with `to`/`cc`/`bcc`, inline HTML/text or a saved template with variables, attachments, and optional scheduled send.
- Rate limits are per mailbox, not per API key: a daily send quota (with an hourly sub-limit to catch bursts) that scales with the mailbox owner's plan. Current tiers — Free: 50/day, Pro: 500/day, Premium: 2,000/day. A mailbox connected over external IMAP relay is not subject to this quota. Exceeding the quota returns HTTP 429. Current limits for an authenticated mailbox are always available live via `GET /subscriptions/me`, which is the source of truth over any number mentioned here.
