Campaign registrations should meet each of the following descriptions for each field.

The description should be thorough and provide an explanation of the campaign’s objective or purpose. Provided description needs to answer who the sender is, who the recipient is, and why messages are being sent to the intended recipient.

“This campaign sends messages to customers”

Message flow/Call-to-Action

The message flow/call-to-actions needs to provide clear and conspicuous details on how an end customer consents to receive messages and understand the purpose of the messaging.

Call-to-Action should contain the following information:

  1. The program or product description

  2. Telephone number(s) from which messaging will originate

  3. Identify of the organization or individual being represented in the initial message

  4. Clear and conspicuous language about opt-in and any associated fees or charges

  5. Compliant Privacy Policy

  6. Other applicable terms and conditions (e.g., how to opt-out, customer care contact information)

Opt-in needs to apply per campaign, should be not transferable or assignable and can not be obscured in terms and conditions (especially terms related to other services). If multiple opt-in methods can be used for the same campaign, please list them all.

A compliant Privacy Policy must state that no mobile information will be shared with third parties/affiliates for marketing/promotional purposes. Information sharing to subcontractors in support services, such as customer service is permitted. All other use case categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties.

Campaign reviewers need to be able to verify details provided in this field. Provide evidence such as a hosted link to screenshot or document for opt-in that occurs behind a gated login or on a paper form.

Successful Example

Message/data rates apply. Consent is not a condition of purchase. [Link to terms and conditions].”
