No. Once a customer opts out of receiving text messages by replying "STOP" or asking to be removed from your list, you cannot legally send them another automated text message, review request, or marketing SMS. The only text allowed after an opt-out is a single, automated response confirming that they have been unsubscribed and will not receive further messages.
Attempting to text an opted-out customer—even months later after completing a brand-new service job—violates federal law and mobile carrier rules. Doing so puts your business at risk of severe fines, carrier blacklisting, and loss of texting privileges.
Why Opt-Outs Are Strictly Enforced
Text messaging is governed by strict federal laws and carrier-level industry standards. When a customer tells you to stop texting them, that command is legally binding and immediate.
Two main regulatory frameworks govern SMS communications for local businesses:
- The Telephone Consumer Protection Act (TCPA): Enforced by the Federal Communications Commission, the TCPA requires businesses to obtain prior express written consent before sending automated commercial or marketing text messages. Under FCC TCPA regulations, a customer has the absolute right to revoke that consent at any time using any reasonable method (such as texting "STOP", "QUIT", or "UNSUBSCRIBE").
- A2P 10DLC Carrier Guidelines: Major mobile carriers (AT&T, T-Mobile, Verizon) enforce messaging rules coordinated by the CTIA. According to CTIA Messaging Principles and Best Practices, software platforms and business phone numbers must automatically process standard opt-out keywords. Sending messages to numbers that have opted out triggers immediate carrier-level filtering and account flags.
Because review requests sent via SMS are classified as commercial outreach, they fall squarely under these rules.
The Single Exception: The Unsubscribe Confirmation Text
There is only one scenario where sending a message after an opt-out is permitted: an immediate, automated confirmation message.
When a customer texts "STOP" to your business number, mobile carriers allow your messaging platform to reply with one final text. This message must:
- Confirm that the opt-out was successful.
- Remind the user how to opt back in (e.g., "Reply START to resume messages").
- State that no further messages will be sent.
An acceptable confirmation text looks like this:
"You have been unsubscribed from [Business Name] automated review requests and texts. No further messages will be sent. Reply START to opt back in."
Once that single confirmation text is sent, your system cannot transmit another automated message to that phone number under any circumstances unless the customer initiates a re-opt-in.
How a Customer Can Opt Back In (And How You Can’t)
If a customer opted out by mistake or changes their mind later, you cannot text them to ask if they want to opt back in. Texting someone to ask "Would you like to start receiving texts again?" is considered a violation of the TCPA because you are using SMS to contact an opted-out phone number.
Instead, the customer must initiate the opt-in process themselves.
How a customer legally opts back in:
- Texting "START" or "UNSTOP": The customer can open their existing text thread with your business phone number and reply "START" or "UNSTOP". Mobile carriers recognize these keywords and immediately clear the block on that specific device.
- Written Consent via Web Form: The customer can fill out a web form or service intake form that clearly includes compliant consent language (e.g., "By checking this box, you agree to receive automated SMS review requests and updates from [Business Name]").
Once the customer performs one of these actions, your system can resume sending automated messages and review requests.
Real-World Scenarios for Home-Service Businesses
Local service providers like plumbers, HVAC technicians, cleaners, and salons run into common edge cases regarding opt-outs. Here is how to handle them properly.
Scenario 1: A customer hires you again six months after opting out
Suppose a homeowner texts "STOP" during a plumbing job in January. In August, they call you back to clear a main sewer line. Once the August job is completed, can you send them an automated review request?
No. Completing a new job or signing a new contract does not automatically override a previous SMS opt-out. Even though you have a fresh business transaction, their phone number remains suppressed in your system until they explicitly text "START" or opt back in in writing.
Scenario 2: The customer says they opted out by mistake
If a client calls your office or tells a technician, "I accidentally texted STOP to your message, but I’d love to leave you a review," do not attempt to manually trigger an SMS from your dashboard.
Instead, instruct the client: "Just open the last text message from our number and reply START. Our system will automatically reactivate text updates for you."
Scenario 3: Can you email them a review request instead?
Email and SMS are governed by different legal frameworks. SMS opt-outs governed by the TCPA do not automatically revoke email consent under the CAN-SPAM Act, provided you haven't combined opt-outs across both channels in your privacy terms.
If a customer opted out of text messages but has not opted out of email communications, sending a review request to their email address is generally permissible. However, always ensure your emails include a clear, one-click unsubscribe link to maintain full legal compliance and respect consumer preferences.
How SoTrustworthy Protects Your Business Automatically
Managing opt-outs manually across spreadsheets or field management software is difficult and opens your business to legal liability. SoTrustworthy handles SMS compliance automatically so you never have to worry about accidentally texting an opted-out customer.
Here is how SoTrustworthy safeguards your sending reputation:

The Penalties for Messaging Opted-Out Customers
Ignoring SMS opt-out requests carries severe real-world consequences for small businesses:
- TCPA Statutory Damages: Courts can award statutory damages ranging from $500 up to $1,500 per individual text message sent in willful violation of the TCPA.
- Immediate Carrier Suspension: Mobile networks monitor messaging threads for texts sent after a "STOP" reply. If a violation occurs, carriers flag your brand registration, block your business phone number, and suspend your text-sending capabilities completely.
- Loss of Brand Trust: Bombarding a customer who specifically asked to stop receiving texts harms your local reputation and increases the likelihood of receiving a negative public review.
Next Steps
