Everything you need to send.

From your first transactional email to million-recipient broadcasts.

Transactional API

Send single or batched emails over a clean HTTP API or SMTP — with idempotency keys, scheduling, and retrieve/cancel.

Broadcasts

Marketing sends to your audiences with reusable templates, chunked fan-out at scale, and RFC 8058 one-click unsubscribe.

Audiences & contacts

Manage lists, import contacts, and honor unsubscribes automatically across every future send.

List verification

Clean lists before you send — syntax, disposable, role, and SMTP-probe checks with a reputation safeguard.

Open & click tracking

Per-message open pixels and click redirects feed an analytics view: sent, delivered, opened, clicked, and rates.

Deliverability built in

SPF, DKIM, and DMARC alignment, domain verification, warm-up ladders, suppressions, and bounce handling.

Ship your first email in minutes.

Add a domain, verify DNS, and start sending — transactional or marketing, from the same platform.
