On your website: With Text sign-ups on, your footer sign-up gets an unticked “Text me updates too” box. People who tick it and add a mobile number join your list, with the exact words they agreed to saved.

1. Your list: everyone who agreed to get texts, how they joined, and when. Only add someone by hand if they agreed in writing; you confirm that each time. Anyone who texts STOP comes off every list right away, and only they can rejoin, from your website.
2. Write your text: up to 320 characters. It always starts with your firm’s name and ends “Reply STOP to opt out.” Guardrail checks every word, just like your site. In Florida and Texas every text starts with “Advertisement:” as the bar rules require; elsewhere you can add it.
3. Send: it goes to everyone on the list who hasn’t opted out. Texts only go out between 9 AM and 8 PM in your timezone; a text sent later waits for 9 AM. One text to the list a day, and up to 2,000 texts a month.
4. History: each send with how many went out, waited, or failed. Your list and every send are in your data download.

What happens next: Texts go out within a few minutes. Texting laws (like the federal TCPA) and your state’s bar rules still apply to what you send; Guardrail is a review aid, not legal advice. Texas firms: some advertising texts must be filed with the State Bar’s Advertising Review Committee.
