- VaultSandbox enables production-like email testing without mocks, ensuring real TLS, DNS, and SPF/DKIM validation within your VPC.
- Supports major email providers like Postmark, SendGrid, and SES, with deployment possible in 5 minutes using Docker Compose.
- Eliminates common testing pitfalls such as fake SMTP environments, polling loops, and shared public inboxes that lead to production failures.
- Provides isolated, encrypted inboxes for secure testing without exposing customer data, with auto-provisioned TLS and DNS.
- Features include real SMTP + TLS termination, full message validation (SPF, DKIM, DMARC), and true isolation with encrypted storage.
- Designed for CI/CD pipelines with ephemeral, in-memory storage, automatic cleanup, and disposable inboxes for high-velocity testing.
- Includes a CLI for real-time email monitoring, SDKs for automated tests, and supports deterministic testing without sleep() statements.
- Open-source core (AGPLv3) with commercially safe SDKs (MIT), no artificial limits, and built-in quantum-safe cryptography.
- Future roadmap includes enterprise features like SSO and audit logs, with current focus on core stability and documentation.
- Addresses common concerns like spam protection, data persistence, and key management, ensuring secure and efficient testing.
