Help me turn my notes into a short thank-you postcard for the contractor who finished our office renovation.

Start with a conversation

1. Tell Instinct what you want to say and which details it may use. Ask it to flag missing information rather than infer an address.
2. Ask it to open PostalMuse if browser interaction is available. Otherwise, bring the approved text or PDF to the mailing form yourself.
3. Review the actual PostalMuse proof and quote. Approve payment yourself; a drafted message is not a sent letter.

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?

Instinct describes computer and phone use, but we have not validated a PostalMuse integration. No native connector or automatic sending is promised. Browser access depends on your Instinct session.

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.

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.
