Documentation
SendBunny is a self-hosted email platform that runs in your own AWS account. The public API is one CloudFront host and one /v1 catalog. Keys live in the dashboard under API keys. Interactive language-tab examples: /docs/reference.
Quickstart: send your first email
Send a transactional email through your self-hosted SendBunny install in four steps: verify a domain, create an API key, copy your endpoint URL, POST JSON.
HTTP API
Complete SendBunny /v1 catalog: auth, scopes, send, inbox, campaigns, audience, templates, domains, and suppression. OpenAPI 3.1 at /openapi.json.
Email templates and merge variables
How SendBunny templates work: merge-tag syntax with fallbacks, required-variable enforcement, aliases, and sending templates through the transactional API.
