Operations for what your agent creates

The subscription pays for maintained adapters, OAuth, scheduler uptime, approval state, retries and history — not for AI tokens.

Agent-native, BYOK

Create content with your own AI — OpenRouter, fal.ai, Google, ElevenLabs. Postward never resells inference and never needs your keys.

Immutable runs

Every version is an immutable run. Revision means a new run — history is never rewritten, and a new run never silently replaces what is live or scheduled.

Multi-level approvals

Ordered approval levels per campaign. Any one member of the current level can advance it. Rejection keeps a comment your agent can read and act on.

Exact-run scheduling

Schedules point at an exact run and destination, stored in UTC with your timezone. The scheduler runs in the cloud — your laptop can be off.

Reliable publication

Attempts are recorded before any remote call. Unknown outcomes block instead of blind-retrying, with explicit reconciliation. Retries never duplicate posts.

Operational memory

What is live, what is scheduled, what was rejected, what was replaced — publication history and audit survive the whole lifecycle.

Your storage — or ours

Bring your own S3-compatible bucket (Wasabi, S3, R2, MinIO) on any plan. Paid plans add Postward-managed storage. Credentials are encrypted and never leave the server.

MCP + REST API

Everything operational is available to your agent over remote MCP with full OAuth — or over the REST API. The Studio is a control plane, not a privileged path.

Remote MCP with OAuth

Connect your agent, not an API key

Add Postward to any MCP-capable client. The first time your agent uses it, a browser window opens for sign-in and consent — no manual API-key copying. Postward's MCP endpoint speaks OAuth 2.1 with PKCE, dynamic client registration and token rotation.
