SMS Opt-In
& Consent

EFFECTIVE MAY 21, 2026 · MUSTSY LLC · TEXAS

This document describes how Mustsy collects and records consent from users who opt in to receive SMS price alerts, the exact language shown to users, the messages we send, and how users opt out. It is provided for carrier and toll-free verification review.

Program Description

Mustsy is a seat alert service. Users create alerts for specific concerts and sporting events with a target price. When matching seats are found at or below the target price, we notify the user. SMS notifications are an optional channel that Pro-tier users can enable in their account settings. Email notifications are the default channel and do not require SMS opt-in.

  • Program name: Mustsy Seat Alerts
  • Brand: Mustsy (MustSy LLC)
  • Use case: Account notifications — automated price-drop alerts the user has configured
  • Message frequency: Varies by user; only sent when a user's own alert matches
  • Cost disclosure: "Msg & data rates may apply" shown at opt-in and in confirmation message

Where Consent Is Collected

Consent is collected on the authenticated Account Settings page at https://mustsy.com/account. The SMS toggle is only visible to users on the Pro tier and is off by default. No SMS is ever sent without an explicit user action in this UI.

Opt-In Flow (Step by Step)

  1. User creates a Mustsy account and upgrades to the Pro tier.
  2. User navigates to Account Settings.
  3. In the SMS Notifications section, the user toggles "Enable SMS price alerts" on and enters their mobile phone number in E.164 format.
  4. User clicks "Activate SMS". This action is the explicit opt-in.
  5. Mustsy immediately sends a one-time confirmation SMS (sample below). The user's record is marked sms_verified = true and a timestamp is stored in sms_opted_in_at.
  6. Only after this point will the user receive seat alert SMS messages, and only for alerts they themselves created.

Consent Language Shown to the User

The following disclosure appears directly next to the SMS toggle and phone number input on the Account Settings page, before the user clicks "Activate SMS":

By enabling SMS alerts and providing your phone number, you agree to receive automated text messages from Mustsy when matching tickets are found at or below your target price. Message frequency varies based on your alerts. Message and data rates may apply. Reply STOP to unsubscribe at any time. Reply HELP for help. See our Privacy Policy and Terms of Service.

Record of Consent

When a user opts in, Mustsy stores the following on their profile record in our database:

  • phone_number — the E.164 number the user entered
  • notify_sms = true — user enabled the channel
  • sms_verified = true — confirmation SMS was successfully sent
  • sms_opted_in_at — UTC timestamp of opt-in
  • sms_opted_out_at — UTC timestamp of last opt-out, if any (null otherwise)

These records are timestamped and retained for the life of the account as proof of consent.

Sample Messages

1. Opt-in confirmation (sent once, immediately on opt-in):

Welcome to Mustsy seat alerts! You'll get notified when your target seats drop to your price.

Reply STOP to unsubscribe at any time. Msg & data rates may apply.

- The Mustsy Team

2. Price alert (sent only when the user's own alert matches):

Mustsy: 2 seat(s) in Section 101 Row A at $85.00 for Travis Scott - UTOPIA. Buy now: https://mustsy.com/api/public/go?alert_id=...

Reply STOP to unsubscribe.
/ 07

Opt-Out & HELP Handling

Users may opt out at any time by either:

  • Replying STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT to any Mustsy SMS — handled by our Twilio inbound webhook, which immediately sets notify_sms = false and stamps sms_opted_out_at.
  • Toggling SMS off in Account Settings.

Users who previously opted out may opt back in by replying START or UNSTOP, or by re-enabling the toggle in Account Settings. HELP replies are answered with our support contact and a link to this page.

Every outbound SMS includes the footer "Reply STOP to unsubscribe." appended by our sending service.

/ 08

Data Sharing

Mustsy does not share, sell, or rent phone numbers or any opt-in information to third parties. Phone numbers are used solely to deliver the seat alerts the user has configured. See our Privacy Policy for full details.
