# Drin

> The complete email platform for your team and its agents — send, receive,
> market. One API, one dashboard, every email. Inboxes on your domain parse
> inbound mail to JSON; campaigns and automations live next to transactional
> sending; a 54-tool MCP server, a CLI and skills expose the whole surface to
> AI agents, with approve-by-reply gating anything wide.

## The three pillars

- [Send](https://drin.run/product/send) — REST API, drop-in SMTP, Node/Python SDKs, templates, signed webhooks. Batch, schedule, attach on one endpoint.
- [Receive](https://drin.run/product/receive) — real inboxes on your domain; inbound mail parsed to structured JSON (threads, attachments, SPF/DKIM/DMARC results) and posted to your webhook.
- [Marketing](https://drin.run/product/marketing) — campaigns, automations, segments and per-topic consent with one-click unsubscribe; nothing launches without a human reply (approve-by-reply).

## Also

- [Forms](https://drin.run/product/forms) — point a plain HTML form at Drin; submissions arrive as email. No backend.
- [Agents](https://drin.run/agents) — MCP server (54 tools), CLI, skills for Claude Code / Cursor / Codex; per-tool setup pages.
- [Deliverability](https://drin.run/deliverability) — unique DKIM selector per domain, one-click DNS via Domain Connect, plan-aware warmup, automatic suppressions. We publish no deliverability percentage.
- [Pricing](https://drin.run/pricing) — free sandbox (100 test messages/month); production from $3/month; no overages. Machine-readable: https://drin.run/pricing.md
- [Docs](https://docs.drin.run) — guides + API reference
- [Status](https://drin.run/status) — live status + incidents
- [Contact](https://drin.run/contact) — support and sales

## What Drin does NOT do

- No SMS, no push notifications — email only.
- No CRM — contacts/segments serve sending, not sales pipelines.
- No cold-email or purchased-list tooling — opt-in mail only (acceptable-use enforced).
- No free production tier — the sandbox is for integration testing; production sending starts at $3/month.
- No published deliverability percentage — your numbers live on your own dashboard.
