Opt-In Language Examples

Good Example: "By providing your phone number, you agree to receive automated marketing messages from [Company] at the number provided. Message frequency varies. Message and data rates may apply. Reply STOP to opt out. Reply HELP for help."

Better Example (High-Risk): "By providing your phone number and clicking 'Subscribe', you expressly consent to receive automated marketing text messages from [Company] about [specific content]. You may receive up to [X] messages per month. Message and data rates may apply. Consent is not a condition of purchase. Reply STOP to unsubscribe at any time. Reply HELP for assistance."
