## Core resources

- [API documentation (curated reference)](https://ixmailer.com/docs): quickstart, auth, REST + SMTP send, webhooks, error codes, rate limits.
- [Interactive API reference](https://ixmailer.com/docs/api): every endpoint with try-it-now, rendered from the live OpenAPI spec.
- [OpenAPI JSON spec](https://api.ixmailer.com/api/docs/openapi.json): machine-readable contract. Stable URL. OpenAPI 3.1.
- [Customer dashboard](https://app.ixmailer.com): sign up, mint API keys, verify domains, view logs.

## Concepts (short)

- [Authentication](https://ixmailer.com/docs#auth): workspace API key (any domain), per-domain API key (one domain), per-domain SMTP credential (SMTP only). All `ixk_…` prefix, all `Authorization: Bearer …`.
- [Sending mail (REST)](https://ixmailer.com/docs#sending): `POST /v1/messages` returns 202 + id. Tracking opens + clicks + per-message overrides.
- [Sending mail (SMTP)](https://ixmailer.com/docs#smtp): `smtp.ixmailer.org:587` STARTTLS or `:465` TLS. Username = full email, password = API key.
- [Sender domains](https://ixmailer.com/docs#domains): register domain, add 4 DNS records, click Re-check DNS. Per-domain settings: tracking overrides, retention.
- [Webhooks](https://ixmailer.com/docs#webhooks): 10 event types (queued/sent/delivered/deferred/failed/bounced/opened/clicked/complained/unsubscribed). HMAC-SHA256 signed.
- [Error codes](https://ixmailer.com/docs#errors): stable machine-readable codes in `{ error: { code, message, details, requestId, timestamp } }`.
- [Rate limits](https://ixmailer.com/docs#rate-limits): per-workspace, scaled by KYC tier. 429 with `retryAfter`.
- [Public signup endpoints](https://ixmailer.com/docs#public-signup): `POST /v1/p/lists/:slug/subscribe` (no API key) + hosted form at `app.ixmailer.com/p/forms/:slug`. Opt-in per list.
- [Subscriber preference center](https://ixmailer.com/docs#preference-center): hosted page at `app.ixmailer.com/p/preferences?t=…` lets recipients toggle list subscriptions instead of all-or-nothing unsubscribe. Opt-in per workspace.
