Adding an address that is already suppressed returns the existing entry unchanged, rather than rewriting why it was suppressed. `reason` accepts `manual` (default) and `unsubscribed`. `bounced` and `complained` are set only by the provider's delivery events, so the record of why an address bounced stays truthful. ## OpenAPI ````yaml /developer/api-reference/openapi.json post /email/suppressions openapi: 3.1.1 info: title: Crevio API V1 version: 1.0.0 description: > API for the Crevio creator platform — a multi-tenant SaaS for digital product sales. Uses snake_case keys following Stripe conventions. All resource IDs are string IDs (e.g., "prod_abc123"). Authentication is a bearer token: `Authorization: Bearer $CREVIO_API_KEY`. List endpoints are cursor-paginated with `limit` and `starting_after`. Writes accept an `Idempotency-Key` header and are safe to retry. Every response carries IETF RateLimit headers (`RateLimit`, `RateLimit-Policy`) so a client can self-throttle, and `Retry-After` on a 429. The quota is 600 requests per minute per credential. The API is versioned in the URL path (`/v1`). Nothing is removed without in-band warning: a deprecated operation is marked `"deprecated": true` here and serves `Deprecation` (RFC 9745), `Sunset` (RFC 8594) and `Link; rel="deprecation"` headers for at least six months before it stops answering.
