Email should be
infrastructure you own
Posthawk started because I was tired of paying per-email fees, being locked into proprietary APIs, and trusting third parties with my users' data. So I built the email platform I wanted to use.
Self-Hostable
Forever
To First Email
Platform Cost
Email is table stakes.
Why is it so hard?
Every product needs email — password resets, onboarding, invoices, notifications. But the options are either expensive SaaS platforms that charge per email and lock you in, or raw SMTP servers that take days to configure properly.
I needed transactional sending, scheduled delivery, inbound receiving, template management, and deliverability monitoring. Three different services, three different APIs, three different bills. None of them let me self-host.
One platform.
You own it.
Posthawk combines sending, scheduling, receiving, templates, contacts, webhooks, and analytics into a single platform. Deploy with Docker in under 5 minutes, connect your sending credentials, and start sending.
Don't want to self-host? The managed cloud starts free with 3,000 emails per month. Scale to millions with pay-as-you-go pricing at a fraction of what other providers charge.
What I believe in
Self-Hostable First
Deploy on your own servers with full control. No vendor lock-in, no data leaving your perimeter.
Self-Hosted by Default
Your data never leaves your servers. One Docker Compose command and you own your entire email pipeline.
Developer Experience
Clean REST API, TypeScript/Python SDKs, React Email templates, and documentation that respects your time.
Privacy by Design
Zero telemetry, zero tracking. Row-level security at the database layer. Your email infrastructure, your rules.
No Vendor Lock-In
Standard protocols. Clean API surface. Export your data anytime. Migrate away in hours if you want to.
Built in Public
Public roadmap, open issues, transparent changelog. I ship in the open and listen to the community.
