Aesthetix CRM uses native Twilio for phone and text messaging. This article explains the core SMS compliance principles every med spa should follow — getting consent, including clear opt-out language, honoring opt-outs, and identifying your business — and how registration and Texas-specific rules apply to your account.
Informational only. This article describes general SMS compliance principles and how they relate to Aesthetix CRM. It is not legal advice, and it does not establish your legal obligations. SMS regulations vary by jurisdiction and change over time. Please consult your own compliance or legal advisor about the requirements that apply to your med spa and your patients.
Because Aesthetix CRM runs on native Twilio, A2P 10DLC and toll-free registration are handled directly on Twilio — and Aesthetix CRM handles your A2P and toll-free registration for you. You do not need to file these registrations yourself.
Registration tells carriers who you are and what kind of messages you send, which improves deliverability and reduces the chance of carrier filtering. Once your numbers are registered, you remain responsible for how you use them — specifically for maintaining proper consent, handling opt-outs, and identifying your business in your messages.
These principles apply to every text you send, regardless of platform. Following them keeps your messaging aligned with TCPA, CTIA, and carrier expectations.
Get consent before texting. Only text patients who have agreed to receive messages from you. Capture and keep a record of that consent (for example, through an intake form or a clear opt-in checkbox).
Include clear opt-out language. Tell recipients how to stop messages, for example "Reply STOP to unsubscribe." Carrier-recognized opt-out keywords include STOP, STOPALL, CANCEL, UNSUBSCRIBE, END, and QUIT.
Honor opt-outs promptly. When someone opts out, stop sending them messages right away. Do not message a contact who has unsubscribed.
Identify your business. Make it clear who is texting, for example "Thanks, Alex at Glow Med Spa." Sender identification builds trust and helps recipients recognize you.
Send periodic reminders. For long-running conversations and recurring campaigns, periodically re-include opt-out instructions and your sender information so recipients always know who is texting and how to stop.
Your responsibility: You control who receives messages, what they say, when they are sent, and whether you have valid consent — so you are the "seller" or "telemarketer" for legal purposes. Aesthetix CRM is a platform provider; maintaining consent, opt-out handling, and sender identification is your responsibility.
Texas amended its telemarketing law (Chapter 302, Business & Commerce Code), effective September 1, 2025, to cover marketing text messages in addition to voice calls. Businesses that send marketing texts to Texas residents — or from a Texas location — may have additional registration and disclosure obligations, and the law makes it easier for individuals to bring lawsuits over violations.
If you send marketing SMS to or from Texas, see the dedicated Aesthetix CRM article "Texas SMS Marketing Compliance (SB 140) — What Aesthetix CRM Customers Need to Know" for what this means and what you need to do.

Do I need to register for A2P 10DLC or toll-free messaging myself?
No. Aesthetix CRM handles your A2P 10DLC and toll-free registration for you on Twilio. You are responsible for how you use your registered numbers — maintaining consent, honoring opt-outs, and identifying your business.
What opt-out language should I include?
Use clear, simple wording such as "Reply STOP to unsubscribe." Carrier-recognized opt-out keywords include STOP, STOPALL, CANCEL, UNSUBSCRIBE, END, and QUIT.
What happens when someone replies STOP?
You must stop messaging that contact promptly. Honoring opt-outs is both a legal requirement and important for deliverability.
Do I need consent before texting a patient?
Yes. Only text patients who have agreed to receive messages from you, and keep a record of that consent.
How does compliance affect deliverability?
Carriers often filter or block messages that are missing proper sender identification or opt-out details, or that go to recipients who never consented. Following the core principles above helps maintain higher delivery rates.
I send marketing texts to or from Texas — is there anything extra?
Possibly. See the Aesthetix CRM article "Texas SMS Marketing Compliance (SB 140) — What Aesthetix CRM Customers Need to Know" for details on the Texas requirements.
