Built for developers,
by developers
Posthawk is an open source email infrastructure platform. We believe email should be a utility you own and control — not a service that locks you in.
Make email infrastructure
accessible to everyone
Every product needs email. Password resets, onboarding sequences, invoices, notifications — they all depend on reliable delivery. But most email services charge per-email fees, lock you into proprietary APIs, and store your data on their servers.
We built Posthawk so any developer can deploy production-grade email infrastructure on their own terms. One Docker Compose command, connect your AWS SES credentials, and you're sending emails with full control over your data and delivery pipeline.

Clean REST APIs, TypeScript SDKs, React Email templates, and comprehensive documentation.
Privacy Focused
