How to Turn Off SMS DND in GoHighLevel: Step-by-Step Guide
GoHighLevel blocks SMS automatically in specific situations. When DND is enabled, messages fail to send. Your contact never receives the text. This creates delays and lost communication.
Turning off DND seems simple but often fails. Many users disable DND, then discover SMS still does not send. Why? DND has multiple causes and layers. Understanding each helps you troubleshoot effectively.
Agencies and businesses depend on SMS for client communication. Appointment reminders, follow-ups, and confirmations all use SMS. When SMS fails, trust breaks down. Clients don’t get critical information.
What is SMS DND?
SMS DND stands for Do Not Disturb. It blocks SMS from being sent to that specific contact only. Email and phone calls to that contact still work normally.
GoHighLevel activates DND automatically in some situations. You can also manually enable DND for any contact. Once activated, GoHighLevel prevents SMS to that contact.
Key points about DND:
DND differs fundamentally from opt-out status. A STOP response creates a legal opt-out. Turning off the DND toggle cannot reverse a STOP opt-out. This distinction matters for your legal protection and compliance.

Why Does GoHighLevel Enable SMS DND?
GoHighLevel enables SMS DND for specific reasons. Understanding these helps you manage contacts better. There are several situations that trigger this.
Contacts Reply STOP to SMS Messages
When a contact sends STOP by text, they opt out. GoHighLevel turns on DND immediately. This blocks future SMS to that number.
Mobile carriers enforce this rule. If you send SMS to opted-out numbers, carriers reject the message. This damages your sending reputation. GoHighLevel blocks these to protect your account.
Here is what happens step by step:
This is automatic and happens instantly every time.
Manual DND Assignment by Users
You can turn on DND manually anytime. This gives control over who gets SMS. Some businesses pause messaging to certain contacts. You might do this for inactive clients.
Manual DND is useful for several reasons:
You maintain full control over this setting.
Workflow-Based DND Triggers
GoHighLevel workflows can enable or disable DND automatically using the DND Contact action. This saves time managing many contacts.
How to Configure Workflow DND
Go to Workflows. Add the DND Contact action. Select enable or disable. Choose the SMS channel. Pick inbound or outbound direction. Set your trigger conditions.
Common triggers include:
Important: Workflows can unexpectedly change DND. Check workflow configurations if DND keeps re-enabling. Test on a few contacts before full rollout.
Carrier Level Blocks
Sometimes carriers block your SMS gateway number. When this happens, messages fail at the carrier level. GoHighLevel may show these failures as delivery errors. Carrier blocks are separate from contact-level DND settings.
Carriers block numbers for these reasons:
Contact your SMS provider to address carrier blocks.

DND vs Opt Out Explained
Many people confuse DND with opt-out. They work differently legally and technically. Understanding this difference protects your business.
What is SMS DND?
DND is a GoHighLevel platform-level control. You toggle it on or off. It blocks SMS only within GoHighLevel. Carriers and other systems do not recognize this setting.
DND is your internal management tool. It does not affect carrier compliance records. Turning it off removes the GoHighLevel system block only.
What is SMS Opt Out?
Opt-out happens when a contact sends STOP. This is legally binding for SMS messaging. Carriers record it permanently in their database. You cannot ignore it or override it.
Opt-out is a legal action by the carrier. GoHighLevel respects this and blocks SMS. The carrier will reject your message. This happens even if you turn off DND.
Key Differences:
Important Rule:
If a contact replied STOP, they are out. Turning off DND will NOT let you send SMS. The message will still fail at the carrier. Carriers enforce opt-out strictly.
Never try to bypass opt-out status. It is illegal and damages your reputation. Check contact history for STOP before sending. If STOP exists, leave DND on.
How START Works:
A contact who sent STOP can opt back in by sending START. The exact keywords and process depend on your SMS configuration. You cannot force or request an opt-in from them.
Once they send the opt-in keyword, GoHighLevel may remove the opt-out status. Verify the contact’s new status before sending SMS. Your SMS setup determines accepted keywords.
Why This Matters:
Sending SMS to opted-out contacts may violate regulations. The TCPA protects consumers from unwanted messages. Non-compliance can result in fines and legal action. Your sending reputation also suffers.
Respect opt-out status without exception. Verify STOP status before sending. Keep consent records for all contacts. Document your compliance practices.
SMS DND: Inbound vs Outbound
DND has two directions that affect different message flows.
Outbound DND
Outbound DND prevents GoHighLevel from sending SMS. This is the setting you turn off to enable SMS sending. When enabled, no SMS goes out to that contact.
Inbound DND
Inbound DND affects incoming SMS from the contact. It blocks messages the contact sends to your number. This is separate from outbound SMS blocking.
Why This Matters
When troubleshooting SMS, check the correct direction. Outbound DND is what blocks your sent messages. Verify which direction is enabled before making changes.

Common SMS Issues and Solutions
SMS Not Sending After Turning Off DND
Your SMS still fails after disabling DND. Several causes can prevent delivery. Troubleshoot systematically.
The most common cause is STOP status. The contact sent STOP previously. They are opted out at the carrier level. Turning off DND does not override carrier blocks.
Check contact history for STOP responses. If STOP exists, wait for opt-in. Never attempt to send to opted-out numbers. Use email or phone instead.
Other causes of SMS failures include:
Troubleshooting steps:
Verify DND is actually off. Check for STOP in message history. Confirm phone number format is correct. Review account restrictions in Settings. Contact GoHighLevel support if the issue persists.
Address each systematically until SMS sends.
