Key Takeaways
- An artisan MTO list is buyers who opted into that maker and SKU family — not everyone who ever browsed “ceramics.”
- Batch-ready SMS is a second list. Do not reuse the “join the waitlist” blast.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Buyer checkout OTP stays off the kiln SIM.
- Idempotency is batch-id plus buyer-id — makers reopen the same firing.
Summary
Scenario 611 is marketplace contact lists for artisan made-to-order and kiln / batch waitlists — not vehicle PPI, not live drop lots, not wholesale RFQ, not auctions. A maker opens a firing. Only buyers who opted into that maker (and often that glaze family) should get “batch is live.” Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: studio dual-SIM plus a spare. Uncapped platform volume is not unlimited carrier SMS. Confirm list APIs in Developer Center.

batch-id + buyer-id — not “ceramics”
A kiln waitlist is not a category dump
Opt-in is maker plus SKU family. “Ceramics” is not a list. If Mira opens a celadon firing, do not page everyone who once favorited a mug.
If you reuse last quarter’s mug list for a new glaze, you will text people who already STOPped that family. Rebuild from live opt-in. Persist batch-id plus buyer-id so a restock does not double-page.
MTO list matrix
| List | Who | Failure |
|---|---|---|
| Waitlist join | Maker + family opt-in | Parent-category dump |
| Batch ready | Waiters for that firing | Join list reused for all SKUs |
| Sold out | Same waiters, once | Hourly “gone” nags |
| Checkout OTP | Auth pool | OTP on the kiln radio |
Batch ready and sold-out
Signed webhooks when a firing opens. Webhooks, DLR. MCP wraps REST only.
Custom SKUs and STOP
Custom commissions stay off the public batch list. Honor STOP. Copyright on designs is not a reason to SMS the whole category tree.
Devices, volume, and airtime
A sloppy category dump burns volume and trust. We meter devices and platform sends. Free (1/300/300) is one maker proof.
Studio operations
Charge the studio chassis before the drop. Setup, Downloads, pricing.
Decision guide
Ship when lists are maker-and-family. Delay if you blast “ceramics.” Not a CodeCanyon artisan pack.
MTO checklist
- batch-id + buyer-id idempotency.
- No parent-category dump.
- Ready list ≠ join list.
- Sold-out once.
