Provide two outbound sample messages that could be delivered. These should not be generic. (i.e., "thanks for your interest" will not be approved.) In addition, a message sample must have opt-out instructions (i.e., "Reply STOP to cancel.") Include the exact wording of what your customers see. Make sure it covers everything required: "Questions or concerns about your invoice or service? Text {Your Number} and we’ll get back to you shortly. Message & data rates may apply. Message frequency varies. Reply HELP for help, STOP to cancel. We don’t share your info. Privacy: [link]. Terms: [link]." This content must also match what actually appears on your invoices or website. If there's no live URL, you will be asked to provide a screenshot or PDF during the verification process.
