Verb reference
YURN’s entire SMS surface is six verbs. Everything else — browsing offers, claiming, tickets — happens on the web via short links. There is no free-text conversation and no bot pretending to chat; a text either matches a verb or gets a single polite pointer to the link.
The verbs
Section titled “The verbs”| Verb | What it does |
|---|---|
JOIN <keyword> |
Opt in to a merchant. The inbound message itself is the consent record. |
YES |
Claim the most recent unexpired offer from that merchant, without opening the link. |
MUTE |
Pause that merchant’s messages for 30 days. Auto-resumes — no action needed. |
STOP |
Permanent opt-out, enforced at the carrier level. Irreversible from our side. |
START |
Re-subscribe after a STOP (this is a carrier requirement — only the customer can undo a STOP, and only this way). |
HELP |
Returns the merchant name, YURN’s contact information, and opt-out instructions. |
Details worth knowing
Section titled “Details worth knowing”JOIN TONYS opts the sender in to the merchant holding the keyword TONYS. Keywords are unique across YURN, first-come first-served. The customer immediately receives one confirmation message naming the business, describing what they’ll get, and listing MUTE/STOP/HELP. A follow-up asking for their first name is optional and never blocks anything.
YES is the shortcut claim. If the merchant has a live, unexpired offer, replying YES claims it exactly as tapping the Claim button would — same inventory, same sequence number — and the customer gets their ticket link by reply. If there’s no live offer, they get a single message saying so.
The pressure valve. MUTE pauses one merchant for 30 days, then quietly resumes. It exists so a customer who’s temporarily tired of messages doesn’t have to choose between annoyance and STOP. From the merchant side: muted followers are skipped at send time and visible (in aggregate) in your follower list. A rising mute rate is feedback about frequency or relevance — listen to it.
STOP — read this one carefully
Section titled “STOP — read this one carefully”STOP is absolute, and on the Free tier it is broader than one business: STOP stops all merchants sending on YURN’s shared number. The customer texted STOP to a phone number, and carriers require that number to go silent for them — every sender on it. This is another reason opt-out rates are monitored per merchant: one merchant’s fatigue costs everyone reach. Pro merchants have their own dedicated number, so a STOP to a Pro merchant affects only that merchant.
STOP cannot be undone by YURN or by any merchant. Only the customer can return, by texting START.
Required by carriers, useful in practice. The reply identifies the program (merchant name and YURN), gives contact details, and repeats how to opt out. HELP never changes any subscription state.
Everything else
Section titled “Everything else”Any message that isn’t one of the six verbs gets a single canned reply pointing at the merchant’s short link — no parsing, no guessing, no AI improvising in your brand’s voice. SMS is the notification and consent layer; the web is where interaction happens.
