Key Takeaways

Verify Core SMS Setup: Always start by ensuring your GoHighLevel phone number and messaging provider (LeadConnector) are correctly configured and have sufficient balance.
Examine Contact and Opt-In Status: Confirm the recipient’s phone number is valid, correctly formatted, and that they haven’t opted out or marked your messages as spam.
Analyze Workflow and Campaign Settings: Review automation triggers, conditional logic, delays, and message content within your GoHighLevel workflows for potential errors or blocks.
Utilize Audit Logs for Diagnosis: GoHighLevel’s audit logs provide crucial information on SMS send attempts, statuses, and error messages, helping pinpoint the exact failure point.
Address Common External Factors: Be aware of issues like carrier filtering, spam flags, and invalid numbers, which often cause delivery failures outside of your direct GoHighLevel settings.
Test Thoroughly and Systematically: Before escalating, perform multiple tests with different numbers and message content to isolate the problem.
Know When to Contact Support: If internal troubleshooting doesn’t resolve the issue, prepare detailed information before contacting GoHighLevel or LeadConnector support.

Step 1: Check Your GoHighLevel SMS Setup Fundamentals

The first place to look when you encounter GoHighLevel SMS delivery issues is your basic account setup. Often, the simplest oversights can cause major headaches.

Verify LeadConnector (or Twilio) Account Connection and Balance

GoHighLevel primarily uses LeadConnector as its native messaging service, which is powered by Twilio in the background. Ensuring this connection is healthy and funded is crucial.

Navigate to Settings: In your GoHighLevel account, go to “Settings” (usually the gear icon at the bottom left).
Check Phone Numbers: Click on “Phone Numbers.” Here, you’ll see your assigned phone numbers.
Review LeadConnector Status: Look for the “LeadConnector” tab or “Provider” column. Ensure your LeadConnector account is connected and active. Sometimes, a disconnection can occur.
Check Account Balance: GoHighLevel SMS relies on a prepaid balance. If your LeadConnector balance is too low, messages won’t send. You can typically find your balance within the “Phone Numbers” section or your main dashboard. Top up if needed. A common reason for GoHighLevel SMS delivery issues is an empty balance!

Confirm Phone Number Configuration and Capabilities

The actual phone number you’re using for SMS delivery needs to be properly set up and capable of sending messages.

Local vs. Toll-Free: Ensure the number you’re using is provisioned for SMS. Most numbers are, but sometimes a number might be voice-only. Toll-free numbers have different regulations than local numbers, so ensure compliance if using one.
10DLC Registration (US/Canada): If you’re sending A2P (Application-to-Person) SMS in the US and Canada using a local 10-digit number (10DLC), you absolutely must be registered. Unregistered 10DLC traffic is heavily filtered or blocked by carriers, leading to severe GoHighLevel SMS delivery issues. Check your GoHighLevel dashboard for 10DLC registration status under “Settings” > “Phone Numbers” > “Trust Center” or similar.

Review Messaging Settings within GoHighLevel

There are general messaging settings that can impact all your SMS activities.

Location-Specific Settings: If you manage multiple locations, ensure you’re checking the settings for the correct location experiencing the GoHighLevel SMS delivery issues.
Compliance Settings: Look under “Settings” > “Business Profile” or “Compliance.” Sometimes, global opt-out settings or message segment limits might be inadvertently enabled, affecting delivery.

Step 2: Examine Specific Conversation & Contact Details

Once you’ve confirmed your foundational setup, it’s time to look at the individual recipient and message.

Check Contact Phone Number Format and Validity

A simple typo can prevent delivery.

International Format: All phone numbers should be stored in international E.164 format (e.g., +1XXXXXXXXXX for North America, +44XXXXXXXXXX for the UK). Missing the “+” or country code is a common cause of GoHighLevel SMS delivery issues.
Valid Number: Is the number active? Does it belong to a mobile device? Messages to landlines or disconnected numbers will fail.
Test with Your Own Number: Try sending a message to your own mobile number to verify basic functionality.

Review Contact Opt-In Status

GoHighLevel is designed to prevent sending messages to contacts who haven’t opted in or have opted out, ensuring compliance.

Contact Profile: Go to the specific contact in GoHighLevel. In their profile, check the “SMS Opted In” status. If it’s “No,” they won’t receive messages.
Manual Opt-In/Out: Sometimes, contacts are manually opted out, or they reply with “STOP” to your messages. If they’ve replied “STOP,” GoHighLevel automatically opts them out.

Look for “DND” or “STOP” Replies in Conversations

Sometimes, the issue isn’t about *sending* but about *blocking* due to prior interaction.

Conversation History: Check the conversation thread with the contact. Look for any “STOP,” “UNSUBSCRIBE,” “END,” “CANCEL,” or “DND” (Do Not Disturb) replies. These keywords automatically opt the contact out of future SMS.
Re-engagement: If a contact has opted out and wishes to re-engage, they typically need to reply “START” or “UNSTOP.” GoHighLevel will automatically opt them back in upon receiving these keywords.

Step 3: Analyze SMS Campaign/Workflow Settings

If your messages are part of an automation, the workflow itself might be the culprit for GoHighLevel SMS delivery issues.

Verify Workflow Triggers and Actions

Ensure the workflow is actually being triggered and the SMS action is correctly configured.

Trigger Setup: Is the trigger correctly set up to enroll contacts? Test the trigger condition to see if contacts are entering the workflow.
SMS Action Step: Within the workflow, double-click the “Send SMS” action.
Correct Phone Number: Is the correct sending number selected? (Especially relevant if you have multiple numbers).
Message Content: Is the message content clear? Avoid excessive use of ALL CAPS, emojis, or suspicious links, which can trigger spam filters.

Check for Conditional Logic Errors

Complex workflows often use “If/Else” conditions that can inadvertently prevent messages from sending.

Pathing Issues: Follow the path a contact is supposed to take. Are they getting stuck in a branch that doesn’t lead to an SMS action?
Custom Fields: If your conditions rely on custom fields, ensure those fields are populated correctly for the contacts experiencing GoHighLevel SMS delivery issues.

Review Delay Steps and Send Times

Sometimes, messages are delayed, not undelivered.

Delay Settings: Check any “Wait” or “Delay” steps before the SMS action. Are they set for too long, or at an odd time?
Time Windows: GoHighLevel allows you to set specific time windows for sending SMS (e.g., 9 AM – 5 PM). If a contact triggers an SMS outside this window, it will be delayed until the next permitted time. Check these settings under your workflow’s “Settings” tab.

Step 4: Dive into the GoHighLevel Audit Logs

GoHighLevel’s audit logs are your best friend for diagnosing delivery problems. They provide a detailed record of what happened (or didn’t happen).

Accessing the Audit Logs

Account Audit Log: Go to “Settings” > “Audit Logs.” This gives you a broad overview of actions taken across your account. While useful, it might not always show granular SMS delivery errors.
Contact’s Activity Tab: This is often more helpful. Navigate to the specific contact’s profile. Look for the “Activity” or “Notes” tab (depending on your GoHighLevel version). Here, you’ll see a log of all interactions, including SMS send attempts and any error messages from the provider.
Workflow Enrollment History: For workflow-related SMS, go to the specific workflow, click on “Enrollment History” or “Reporting.” Find the contact and look at their journey. It will often show if an SMS step failed and why.

Interpreting Log Entries

Look for specific error messages. Common ones include:

“SMS failed: Twilio Error 30006 – Unreachable destination handset”: Often means the number is invalid, disconnected, or a landline.
“SMS failed: Twilio Error 30007 – Message filtered”: This points to carrier filtering (spam, content, 10DLC).
“SMS failed: Twilio Error 30008 – Unknown Destination Handset”: Similar to 30006, the number isn’t valid.
“SMS failed: Twilio Error 21610 – The ‘To’ phone number is not a valid mobile number”: Exactly what it says.
“SMS failed: Account balance too low”: Self-explanatory, top up your LeadConnector balance.

These error codes directly tell you why GoHighLevel SMS delivery issues are happening.

Step 5: Test and Re-test Your SMS Functionality

After making changes, it’s crucial to test your setup.

Send a Test SMS

Direct Send: From the contact’s profile in GoHighLevel, try sending a direct SMS. Does it go through?
Test Workflow: If the issue is with a workflow, create a test contact (using your own number or a colleague’s) and put them through the workflow. Monitor their journey and the outcome of the SMS step.

Use a Different Test Number

If your test messages still aren’t going through, try sending to a completely different mobile number, ideally from a different carrier. This helps rule out specific carrier blocks or issues with your primary test device.

Step 6: Common Roadblocks and Quick Fixes for GoHighLevel SMS Delivery Issues

Sometimes the problem lies outside of GoHighLevel’s direct control but within common industry practices.

Carrier Filtering

Mobile carriers use sophisticated filtering systems to block spam, fraud, and unwanted messages. This is a major cause of GoHighLevel SMS delivery issues.

Content-Based Filtering: Avoid spammy keywords (e.g., “FREE MONEY,” “ACT NOW!!!”), excessive capitalization, unusual characters, or suspicious-looking links.
Link Shorteners: Generic link shorteners (like bit.ly, tinyurl) are often flagged by carriers. Use custom branded domains for your links if possible, or GoHighLevel’s built-in link shortener, which is generally more trusted.
Volume and Frequency: Sending a large volume of identical messages in a short period can trigger filters.
10DLC Registration: As mentioned, for local numbers in the US/Canada, unregistered traffic is aggressively filtered. Ensure your brand and campaigns are fully registered.

Invalid or Blocked Phone Numbers

Beyond formatting, a number might simply not exist, be disconnected, or the recipient’s carrier might be blocking it.

Number Validation Tools: While GoHighLevel has some internal checks, using a third-party number validation tool can sometimes identify hard-to-spot issues.
Recipient Blocked: The recipient might have blocked your number directly on their phone. This is outside GoHighLevel’s control.

Account Balance Issues

This is a quick fix! Always ensure your GoHighLevel (LeadConnector) balance is topped up. No balance means no sends, leading to immediate GoHighLevel SMS delivery issues.

Compliance & Opt-Outs

Always respect opt-out requests and ensure your messages include clear opt-out instructions (e.g., “Reply STOP to unsubscribe”). Failing to do so can lead to carriers blocking your messages and even legal repercussions. GoHighLevel automatically handles “STOP” replies, but awareness is key.

Step 7: When to Contact GoHighLevel Support

If you’ve gone through all these steps and are still experiencing GoHighLevel SMS delivery issues, it’s time to reach out for professional help.

Prepare Information: Before contacting support, gather all relevant details: the specific contact(s) affected, the time/date of failed sends, the workflow or campaign involved, and any error messages from the audit logs.
Provide Screenshots: Screenshots of settings, audit logs, and contact profiles can greatly assist the support team.

Conclusion

Troubleshooting GoHighLevel SMS delivery issues doesn’t have to be a daunting task. By systematically working through your setup, checking contact details, analyzing workflows, and leveraging the audit logs, you can identify and resolve most common problems. Remember to keep an eye on external factors like carrier filtering and always maintain a healthy LeadConnector balance. With these steps, you’ll ensure your crucial SMS communications are delivered reliably, keeping your business running smoothly and your clients engaged. Happy messaging!
