Acceptable Use & Messaging Policy

Last updated: June 2026

This Acceptable Use & Messaging Policy (the “Policy”) governs how you may use DispoStack and, in particular, how you may use it to send communications such as email and text (SMS/MMS) messages. It supplements and is incorporated into our Terms of Service; capitalized terms have the meaning given there. By using the Service — and especially any messaging feature — you agree to this Policy. If you do not agree, do not use the affected features. We may suspend or terminate access for violations, as described below.

1. General acceptable use

You agree not to, and not to allow anyone using your account to:

  • use the Service to violate any law or regulation, or to infringe, misappropriate, or violate any third party’s rights;
  • send unlawful, deceptive, fraudulent, harassing, threatening, obscene, or unsolicited communications;
  • upload or transmit malware, attempt to gain unauthorized access, probe or test the security of the Service, or interfere with its normal operation;
  • scrape, harvest, resell, or systematically extract data except through features we provide for that purpose;
  • reverse engineer or attempt to derive source code, except where that restriction is prohibited by law; or
  • misrepresent your identity, business, or affiliation, or use the Service to defraud or mislead anyone.

2. You are the sender

When you send communications through the Service, you — and not DispoStack — are the “sender,” “telemarketer,” “advertiser,” and initiator of those communications for all legal and regulatory purposes. The Service is a tool that transmits messages you choose to send to recipients you choose. You are solely responsible for your recipients, your message content, and your compliance with all applicable laws, carrier requirements, and industry standards, including (without limitation) the Telephone Consumer Protection Act (TCPA), the CAN-SPAM Act, the Telemarketing Sales Rule, state telemarketing and do-not-call/do-not-contact laws, and messaging registration requirements such as A2P 10DLC.

3. Consent (opt-in) is required

You may only send messages to recipients who have given you the consent required by law for the type of message you are sending, and you must be able to produce evidence of that consent on request. Consent must be obtained directly by you; it cannot be bought, sold, rented, shared, or assumed, and a pre-existing list, a public record, or the fact that you have someone’s phone number is not, by itself, consent. You may not message anyone who has not consented or who appears on an applicable suppression or do-not-contact list.

4. Identification and opt-out (STOP)

Every message must clearly identify you or your business as the sender. Your initial message in any conversation must include clear opt-out instructions (for example, “Reply STOP to unsubscribe”). You must honor opt-out requests immediately and permanently — when a recipient replies STOP, UNSUBSCRIBE, or a similar keyword, their consent is revoked and you may not message them again unless they re-consent. The Service helps by processing STOP replies automatically, but you remain responsible for honoring all opt-outs across every channel.

5. Prohibited message content

You may not send messages that promote, facilitate, or relate to content prohibited by carriers or law, including:

  • sexual or adult content; hate speech or content that is harassing, violent, or discriminatory;
  • alcohol, tobacco, vaping, cannabis, or controlled substances, or any illegal product or service;
  • firearms, weapons, fireworks, or related accessories;
  • high-risk or deceptive financial offers (such as payday or short-term loans, debt collection or relief, or get-rich-quick/“guaranteed money” schemes) except in strict compliance with applicable law and carrier rules;
  • phishing, fraud, deceptive marketing, malware, or links that conceal their destination; or
  • any content that violates a carrier’s messaging rules or that we reasonably determine creates risk for the platform or other users.

6. Frequency, quiet hours, and good practice

Send only the messages a recipient would reasonably expect, at a reasonable frequency, and within lawful contact hours (respecting quiet-hours and time-zone restrictions). Do not use unregistered or misleading sender information, do not attempt to evade spam filtering or carrier controls, and do not send content designed to provoke a high reply rate without legitimate purpose.

7. Carrier registration (A2P 10DLC)

U.S. business text messaging must be registered with mobile carriers before it can be delivered reliably. To use text messaging, you must provide your accurate business identity (including your legal business name and tax identification number/EIN, or eligible sole-proprietor details) and a truthful description of how you will use messaging, including your consent practices and sample messages. We facilitate this registration on your behalf, but the registration is yours — you are the registered business and sender. You may not send messages before your registration is approved, and you may not misrepresent your identity, your use case, or your consent practices in any registration.

8. Carrier penalties and fees are your responsibility

Carriers and their registration partners may impose fees, filtering, throttling, blocking, or financial penalties for messaging that violates their rules or the law. Any such penalties, fees, or charges arising from your messaging are your responsibility, and we may charge or pass them through to you in addition to any usage charges. You are also responsible for your prepaid balance remaining sufficient to cover your messaging.

9. Monitoring, enforcement, and suspension

We may monitor for compliance and may, at our discretion and without prior notice, throttle, pause, suspend, or terminate messaging or account access that we reasonably believe violates this Policy, the law, or carrier rules — including automatically pausing messaging that shows high opt-out or complaint rates. We may also remove content, report violations to carriers or authorities as required, and reclaim a messaging number on suspension or cancellation. These remedies are in addition to any others available to us.

10. Your responsibility and indemnification

You are solely responsible for your messaging and for the consent and data of the people you contact. You agree to defend, indemnify, and hold harmless DispoStack and its owners, officers, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising from or related to your communications, your violation of this Policy or any law, or your registration representations, as further described in our Terms of Service.

11. Changes and contact

We may update this Policy from time to time; material changes take effect as described in our Terms, and your continued use after a change constitutes acceptance. Questions about this Policy or to report a violation: legal@dispostack.com.
