Use the REST API for app code, or SMTP for frameworks and existing tools.
The pieces small teams usually need first: domain authentication, sending keys, logs, webhooks, and bounce handling.
We generate the DNS records. You add them. One-click verification checks everything.
Use account API keys for application code, or per-domain SMTP keys for frameworks, CMS tools, and legacy apps.
Receive signed events for accepted, failed, bounced, soft-bounced, and suppressed messages.
Create reusable templates with variables. Send with a template slug instead of inline HTML.
Track every email with status timeline, delivery attempts, and bounce reasons. Filter and search.
SHA-256 hashed keys. DKIM private keys encrypted at rest. CSRF protected. Not an open relay.
