An email APIfor builders.
Build on an API that matches how serious teams operate: explicit domain state, routing, and operational signals—not a single opaque “send” button.
An email API lets your systems create, configure, and send mail programmatically.
Developer velocity dies when email infra is split across five vendors with different auth models and no shared audit trail.
CloudJet aligns API workflows with SMTP access, monitoring, and guardrails so engineering and deliverability share one system.
Designed for real integrations
Use the API for provisioning, verification checks, operational queries, and sending workflows that need structured responses.
Pair with webhooks where you need asynchronous delivery and reputation signals in your own systems.
Questions, answered.
Yes. Many teams send transactional traffic via SMTP while using the API for domain lifecycle, verification, and operational automation.
