Dual-mode email platform combining safe dev/test sandbox email capture with production transactional SMTP and API sending. Team inbox with real-time preview. HTML rendering and spam score analysis. Well-suited for CI pipelines and staging environments. Confidence is docs-derived.
REST API for transactional email sending with template and variable support. Sandbox API for programmatic inbox and message inspection. Per-environment SMTP credentials. Webhook events for delivery status. Bulk send endpoint for batch operations.
API token authentication for REST and sandbox APIs. Per-project SMTP credentials scoped to sandbox or production. Account-level API key with project-level isolation. Test vs. production environment separation enforced at credential level prevents accidental production sends.
Detailed bounce, delivery, and complaint event webhooks. Spam score and HTML compatibility analysis in sandbox. DKIM/SPF feedback in sending reports. Structured error responses with code and message. Rate-limit responses include Retry-After guidance.
Clear separation of sandbox and production in docs and UI. SMTP and API sending examples in Node.js, Python, PHP, and Ruby. Template editor with live preview. Generous free tier for sandbox use. Straightforward onboarding flow for both test and production sending. Confidence is docs-derived.
