Use the approved release summary to prepare a thank-you postcard for this design partner. Keep it short and show me the final proof.

Build a small, reviewable mailing workflow

  1. Open the PostalMuse quickstart in your agent context. Use a Cursor environment with the shell and HTTPS permissions needed to run it.
  2. Keep approved content separate from credentials. Create a sandbox draft, inspect the PDF proof, and handle returned errors using the documented recovery actions.
  3. For production, check current availability and require a review handoff or a valid spending grant. Persist mailing IDs so rerunning a script cannot accidentally resend the same task.

Use PostalMuse at https://postalmuse.com. Read https://postalmuse.com/skill.md and https://postalmuse.com/openapi.json if you can access them, and check https://postalmuse.com/v1/capabilities before attempting API preparation. First tell me whether this session can use an authorized browser or HTTP tool. If it cannot, help me prepare the text or PDF and direct me to https://postalmuse.com/compose; do not claim to have created a mailing. Ask for missing required details and use only the records I authorize. If live sending is unavailable, tell me and stop; do not substitute a simulated send. Show every proof page and the exact quote before requesting my approval. Do not pay or send without my explicit approval or an existing valid spending grant covering this mailing. Keep credentials private. Reuse the same idempotency key for retries and inspect the existing mailing if its outcome is uncertain.

What’s available today?

This page describes a custom REST workflow, not a Cursor extension or marketplace integration. Cursor environments vary, and PostalMuse compatibility testing remains pending.

PostalMuse provides US 4×6 postcards and US Letter documents up to 20 source pages. No native scheduling, campaigns, international mail, or Certified Mail. An external scheduler or CRM remains outside PostalMuse.

Setup guidance reviewed September 25, 2026. This page is not an endorsement or official partnership.

You approve the mailing.

Creating a draft does not send it. Check both postcard sides or every letter page, confirm the addresses and exact price, then approve. If your agent cannot inspect the proof, review it yourself.
