About
Transactional email, built like a serious product.
Sendaro is the control plane for verifying a domain, creating an API key, and sending email.
What we believe
- Tenant isolation is enforced server-side on every org-scoped resource.
- Email is never sent from HTTP request handlers — always durable jobs.
- Credits are an immutable ledger. No silent balance mutations.
- No fake metrics, logos, certifications, or dead buttons.
How we build
The product ships as vertical slices: schema, API, authz, workers, UI with empty/loading/error states, and tests. Marketing reads plan configuration from the database. Providers hide behind interfaces so mocks stay first-class in development.
Brand-wise we aim for technical, clean, and confident — strong type, subtle borders, light and intentional dark modes. Not purple-gradient slideware.
