# Mailmark

Mailmark is an email hosting and campaign platform for custom domains. Connect a domain you own, create mailboxes like `support@yourco.com`, and run day-to-day email, bulk campaigns, and transactional sending from one dashboard or from the REST API.

## What you get

- **Custom domain email hosting** - send and receive from your own domain without running mail servers. Mailmark handles the infrastructure on Amazon SES.
- **A full email client** - inbox, sent, outbox, drafts, and trash for every mailbox, in the browser.
- **Email campaigns** - bulk sends with personalisation, open and click tracking, follow-up sequences, and real-time analytics.
- **Email warmup** - automated warmup that builds sender reputation before you send at volume.
- **REST API and npm SDK** - `mailmark-sdk` for Node.js, TypeScript, and Bun; API keys prefixed `dm_live_`.
- **BYO-AWS** - optionally run the same SES / S3 / Lambda / SNS resources inside your own AWS account.

## How it works

1. Add your domain in Dashboard -> Domains and choose Mailmark-hosted infrastructure or your own AWS account.
2. Add the DNS records Mailmark generates (MX, SPF, DKIM, DMARC) at your registrar and click Verify.
3. Create mailboxes on the verified domain.
4. Send from the dashboard, the REST API, or the npm SDK.
