About send0

We're building the messaging infrastructure developers deserve.

Our Mission

Messaging infrastructure hasn't kept up with how developers build. You still need separate providers for email, WhatsApp, and SMS — each with its own API, dashboard, and billing. send0 replaces that fragmentation with a single integration layer that handles routing, compliance, and delivery across every channel.

What We Believe

Developer experience is product

APIs should be intuitive, documentation should be complete, and error messages should be helpful. We treat DX as a core feature, not an afterthought.

Transparency over complexity

Simple pricing, open API design, and full visibility into delivery status. No black boxes, no hidden fees, no vendor lock-in.

Infrastructure should be invisible

You shouldn't have to think about SMTP servers, carrier routing, or compliance regulations. We handle the infrastructure so you can focus on your product.

Our Approach

We're building send0 in phases. Email first — done properly, with full infrastructure ownership. Then WhatsApp and SMS, using the same unified API surface. One channel done perfectly beats three channels done poorly.
