Yes, but you cannot send a text from an ATDS that says, “Sign up for our marketing program.” That message would be marketing in and of itself, and you would have already violated the Telephone Consumer Protection Act (TCPA). However, you could do a call to action that says, “For automated offers, text DISCOUNT to XYZ number…” When the consumer responds to your offer, request a double opt-in, and get the consumer to agree to the required disclosures. Always ensure full TCPA disclosures are utilized, as well as an opt-out instruction.
