# Batch, bulk, domains, monitors, MCP and free tools

Volume endpoints, domain intelligence, list monitoring, a browser endpoint, an MCP server, and the first free tools.

Date: 2026-08-31

- `POST /v1/email/batch` verifies up to 50 addresses in one request.
- `POST /v1/email/bulk` queues up to 100,000 addresses, with an HMAC-signed completion webhook, cancellation, and CSV results.
- `GET /v1/email/domain/{domain}` answers MX, provider, SPF and DMARC, registration age, and list membership for a whole domain.
- A per-account suppression list: undeliverable verdicts are remembered, and existing lists can be imported.
- Scheduled list monitors re-verify a list on a cadence and alert when its deliverability decays.
- Publishable keys (`pk_…`) power a browser endpoint locked to allowed origins.
- An MCP server lets AI agents verify addresses with an existing API key.
- Four free tools without signup: email checker, MX lookup, SPF and DMARC checker, and disposable domain checker.
- The documentation became a multi-page area with a getting-started guide, an email verification guide, and the API reference.
- The product is now Spaw at spaw.co.
