REST API
Send transactional messages with a clean JSON API and predictable errors.
Email API
Email for
developers
Zend is the best way to reach inboxes. REST API, verified domains, API keys, and logs — the experience you expect from a modern email platform, powered by Amazon SES under the hood.

Built for product teams who care about deliverability, security, and developer experience.
Domains & DNS
Register domains, copy DNS records, and verify with SES before you send.
Logs & keys
Project-scoped API keys, revocable anytime, with a searchable send log.
Tenant isolation
Organizations and projects keep customer data separated by design.
Rate limits
Sensible defaults on auth and send endpoints to reduce abuse.
Delivery honesty
We distinguish provider acceptance from inbox delivery — no fake “delivered” states.
