Removing an address that was not suppressed is not an error. **Early access.** This endpoint returns `403 EMAIL_EARLY_ACCESS` until the email product reaches general availability. The contract below is stable and safe to build against. ## OpenAPI ````yaml /api-reference/openapi.json delete /email/suppressions openapi: 3.1.0 info: title: Political Comms API summary: >- Direct-to-carrier political texting API for campaigns, PACs, advocacy organizations, fundraisers, and elected officials. description: >- Public REST API for the Political Comms platform. Surfaces include Projects (compose, test, schedule, send), Conversations (read inbound threads and reply inside them), Contact Lists (S3 import and analysis), Media Files, Organizations and hierarchy, Brands, Campaigns, Tracking Domains, Phone Numbers, Analytics, and Billing. Authentication is an API key passed in the `X-API-Key` header. Keys are generated from the dashboard at Admin → API and are prefixed `pc_live_`. All POST and PATCH endpoints that mutate state are designed to be safe to retry, with optional `Idempotency-Key` headers for stronger guarantees. Rate limit is 100 requests per minute per key (60-second sliding window; write-only keys 60/min, delete-only keys 30/min; the `X-RateLimit-Limit` header reports your key's exact limit). Webhooks emit `message.sent`, `message.delivered`, `message.failed`, `message.replied`, and `link.clicked` events. Payloads are HMAC-signed; validate the signature before trusting any payload. A Model Context Protocol (MCP) server is available at https://docs.politicalcomms.com/mcp for AI agents that need to search the documentation programmatically. The developer hub at https://politicalcomms.com/developers/ has quickstart examples in cURL, raw HTTP, and Python. version: 1.4.0 termsOfService: https://politicalcomms.com/terms/ contact: name: Political Comms Support email: support@politicalcomms.com url: https://docs.politicalcomms.com license: name: Proprietary url: https://politicalcomms.com/terms/ x-logo: url: https://politicalcomms.com/images/brand/pcomms-logo-left-of-text.png altText: Political Comms backgroundColor: '#ffffff' href: https://politicalcomms.com/ x-mcp: url: https://docs.politicalcomms.com/mcp discovery_url: https://docs.politicalcomms.com/.well-known/mcp transport: http auth: none tools: - search_political_comms - query_docs_filesystem_political_comms - submit_feedback servers: - url: https://api.politicalcomms.com/v1 description: Production security: - ApiKeyAuth: [] tags: - name: Projects description: Create, edit, test, schedule, and inspect projects. - name: Conversations description: >- Read inbound threads and reply inside them from the same number.

Reusing a key with a different request body returns `422` (`IDEMPOTENCY_MISMATCH`); a duplicate sent while the first call is still running returns `409` with a `Retry-After` header.
