It is expected for all customers to refrain from engaging in disallowed content. It is also expected that when restricted content is allowed, customers follow the guidelines for each content type. Please note that any forbidden use cases listed below are not only related to the content of the message but also the business type itself.
Additional Restrictions
If a specific use case is not listed as prohibited or with guidelines here, the content may still be subject to restrictions. For example, the use of shared or free public URL shorteners is not permitted and will lead to filtering. Ensure that when using a shortened URL, it is company branded.
Messaging Categories, Examples, and Notes
The list below covers our most common messaging categories. If you need help with content that isn’t listed here, please contact our support team.
CATEGORY | EXAMPLES | NOTES |
High-risk financial services |
| "Third-party" refers to any entity other than the one providing the loan.
First party loan content is acceptable in the US if it is not promotional messaging, unless it is on an approved Short Code.
Businesses that solely operate in stocks, investing, or cryptocurrency are only permitted to send SMS messages related to two-factor authentication (2FA). |
Lead Generation |
| Any third-party use cases are strictly forbidden. Consent must be obtained directly from end-users.
Any business with a terms of service or privacy policy that mentions sharing or selling consumer data/opt-in information is considered noncompliant. |
3rd Party Debt Forgiveness |
| “Third-party" means originating from any party other than the one which will service the loan.
For example, a hospital could send messages regarding bills for its own patients, assuming they provided opt-in to receive that messaging.
While third party debt collection is not permitted, a debt collection business that has direct consent from end-users (first party) to send related content may do so.
Debt consolidation, debt reduction and credit repair programs are prohibited regardless of if there is first-party consent. |
“Get Rich Quick” Schemes |
| Use cases in this category involve minimal effort for substantial and/or assured financial gains. Such cases often lead to high consumer complaints in the telecom industry and are therefore not allowed on carrier routes. |
Job Postings |
| Third party job boards are disallowed. |

Messaging Regulators
Because guidelines are forever changing. Always reference details of the following:
FCC (Federal Communications Commission): An independent U.S. government agency that regulates interstate and international communications, including phone, radio, TV, satellite, and cable; The FCC creates and enforces rules that implement the TCPA, including protections against unwanted robocalls and texts.
TCPA (Telephone Consumer Protection Act): A U.S. federal law passed in 1991 to curb unwanted telemarketing calls, robocalls, and certain text messaging practices; It requires businesses to obtain proper consent before calling or texting consumers and mandates compliance with do‑not‑call rules.
CTIA (Cellular Telecommunications Industry Association): A trade association representing the U.S. wireless communications industry; CTIA does not create laws but publishes industry guidelines and best practices for mobile messaging, including SMS and MMS; Their standards influence how carriers and messaging providers manage consumer protections, spam prevention, and message deliverability.
CASL (Canada’s Anti‑Spam Legislation) is the federal law governing SMS/text messaging compliance in Canada. CRTC (Canadian Radio‑television and Telecommunications Commission) is the main body responsible for enforcing SMS and text‑message compliance under CASL. It investigates non‑compliant SMS campaigns, issues penalties and compliance orders, and monitors spam, unsolicited texts, and improper opt‑in practices.
Note: ClickSend works closely with the regulators mentioned above, and provides guidance based on audit feedback, registration outcomes, and carrier requirements. Our goal is to help you get approved and remain compliant.
However, carriers have the final say on all approvals and may have additional requirements that are not publicly documented.
