The concept: a guide and checklist for permission-based texting. Its whole point fits in one line: text only people who said yes, and let them leave with one word, STOP. It explains good practice; it is not legal advice.
The sign-up says who will text, what about, and roughly how often. The box starts empty; the customer ticks it.
A first text confirms the sign-up and repeats how to stop. Keep a record of when and how each person said yes.
Only the kind of message people signed up for, at hours that suit them, and never more often than you said.
One word, any time, honored right away. One last text confirms they are out, and then nothing more.
Marketing texts are regulated: the TCPA in the US and CASL in Canada set consent rules, and other places have their own. A guide on this name would explain good practice in plain words and send readers to a lawyer for their own program.
A name for texting done with permission. The domain is for sale.
