Private beta product surface

The current product includes deliverability tests, recipient validation, bulk CSV jobs, API keys, webhooks, domain monitoring, DMARC ingestion, notification channels, placement beta, and SDKs.

Deliverability testing

Generate a real test inbox, send a message from your app or ESP, and inspect authentication, DNS, headers, content, and links.

Email validation

Classify addresses as valid, invalid, risky, catch-all, unknown, disposable, role-based, or typo-prone before a send.

Bulk CSV jobs

Upload lists, track progress, download enriched CSV output, and receive signed webhook callbacks when jobs finish.

Domain and DMARC monitoring

Verify sending domains, scan policy drift, ingest aggregate reports, label sources, and alert on alignment failures.
