GHL SMS Delivery Troubleshooting — Texts Not Reaching Clients
When GHL shows a message as "sent" but the client never receives it, use this guide to diagnose and resolve the issue. This is a high-priority problem — if clients do not receive your texts, they may think you are a scam when you call.
Symptoms
- GHL shows message status as "sent" or "delivered" but client says they never got it
- Client does not respond to any texts but answers calls
- Client accuses you of being a scam because they have no text history from you
- Contact is NOT on DND in GHL but still not receiving messages
Step-by-Step Troubleshooting
Step 1: Verify in GHL
- Go to the contact record → Conversations tab
- Confirm the message shows as "Delivered" (not just "Sent" or "Failed")
- Check if the contact has DND enabled — toggle it off if so
- Verify the phone number is correct and includes the country code
- Check if the number is a landline (landlines cannot receive SMS)
Step 2: Check for Carrier Spam Filtering
This is the #1 cause of undelivered texts. Mobile carriers (T-Mobile, AT&T, Verizon) aggressively filter business SMS.
• Message contains spam trigger words (see SMS Guidelines page for blocked words list)
• Too many messages sent to the same number in a short period
• Client previously marked your number as spam
• A]2P (Application-to-Person) filtering flagged the message pattern
• Your sending number has a low trust score with the carrier
Step 3: Ask the Client to Check
When you get the client on a call, ask them to:
- Check their spam/junk folder — some phones auto-filter unknown numbers
- Search for your number manually in their Messages app
- Check if they blocked the number accidentally
- Check their carrier settings — some carriers have spam filtering that can be adjusted
Step 4: Workarounds
- Have the client save your number as a contact — this dramatically reduces spam filtering
- Send a shorter, simpler first message — avoid links, emojis, and marketing language in the first text
- Try calling first, then text — once a call is established, texts are less likely to be filtered
- Use email as backup — if SMS is consistently blocked, switch to email + phone calls
Step 5: Escalate if Persistent
If the issue affects multiple clients or persists after the steps above:
- Report in #improvement-requests with: client name, phone number, what you tried, screenshots
- Tag @Sam — he can check the GHL sending reputation and A2P registration status
- Include whether this is a one-off or affecting multiple contacts
Prevention Tips
- Always introduce yourself and the company in the first message
- Avoid spam trigger words (see SMS Guidelines → Compliance section)
- Do not send rapid-fire multiple messages — compose one clear message
- Encourage clients to save your number during onboarding calls
- If a client is not responding to texts at all, switch to phone calls immediately — do not keep texting into the void

Client-Side Fixes (When Sends Show Delivered But Client Says Nothing Received)
Added 2026-04-20 from #improvement-requests thread (Reggie + Orlie). Use these when GHL shows the message as sent/delivered but the client swears they never got it and accuses us of being a scam.
Start to that number to re-enable delivery on their side.
Common symptoms this fixes: "Your texts keep going to my spam," "I thought you were a scam," "I never got any message from you," and "Your number shows as spam even though I have it saved" (this last one almost always means the number was saved after the carrier had already flagged it — have them delete and re-add).
