Team crmsupport.io•January 2025•7 min read
WhatsApp is one of the most powerful communication channels inside
CRM Support,
especially for appointment reminders, follow-ups, confirmations, and automated workflows.
But sometimes students, leads, or customers don’t receive your WhatsApp messages—even though CRM Support shows “Not Delivered” or the message appears stuck in a workflow.
This guide explains exactly why WhatsApp messages fail in CRM Support and how to diagnose and fix each issue using message logs, workflows, and provider settings.
But sometimes students, leads, or customers don’t receive your WhatsApp messages—even though CRM Support shows “Not Delivered” or the message appears stuck in a workflow.
This guide explains exactly why WhatsApp messages fail in CRM Support and how to diagnose and fix each issue using message logs, workflows, and provider settings.
1. The Contact Is Outside WhatsApp’s 24-Hour Window
WhatsApp only allows freeform messages inside a **24-hour conversation window**.
If the contact has not replied in 24 hours, CRM Support can only send a **pre-approved WhatsApp template**.
If you try to send a normal message inside a workflow (e.g., “Hello, just checking in”), CRM Support will mark it as: Failed — Outside Session Window.
Fix:
If the contact has not replied in 24 hours, CRM Support can only send a **pre-approved WhatsApp template**.
If you try to send a normal message inside a workflow (e.g., “Hello, just checking in”), CRM Support will mark it as: Failed — Outside Session Window.
Fix:
- Use a WhatsApp template message instead of “Custom Message”
- Check the 24h cutoff in the Message Log
- Trigger a new conversation only with a template
2. The Message Template Was Not Approved by Meta
For WhatsApp Business API inside CRM Support (Twilio, 360Dialog, Cloud API), templates must be
approved inside Facebook Business Manager.
A message fails when:
“Template not approved / template does not exist”.
Fix:
A message fails when:
- The template is still pending review
- The template was rejected
- Variable placeholders were inserted incorrectly (e.g. {{name}} mismatch)
- The flow attempted to use an old or deleted template
“Template not approved / template does not exist”.
Fix:
- Verify the template in Meta → WhatsApp Manager → Message Templates
- Check if the template name matches exactly (case-sensitive)
- Ensure all placeholders {{1}}, {{2}}, {{name}} are provided correctly in CRM Support
3. The Recipient Is Not a Registered WhatsApp User
CRM Support cannot deliver WhatsApp messages to numbers that:
Fix:
- Don't have WhatsApp installed
- Deleted the account
- Use a landline
- Recently changed their number
Fix:
- Confirm the number is an active WhatsApp user
- Ensure E.164 format (+1 XXX XXX XXXX)
- Clean your contact lists before sending workflows
4. The Contact Blocked Your WhatsApp Business Number
When a lead blocks your WhatsApp Business number:
Fix:
- The message will show “Sent” but never “Delivered”
- CRM Support logs will show repeated delivery attempts
- Your workflow will continue but WhatsApp will permanently reject the message
Fix:
- Switch to SMS or Email fallback
- Use CRM Support workflows to detect failed WhatsApp attempts and retry via another channel
5. Invalid Number Formatting Inside CRM Support
WhatsApp requires phones in **E.164 format**:
+15551234567
CRM Support messages fail if numbers contain:
Fix:
+15551234567
CRM Support messages fail if numbers contain:
- Parentheses
- Dashes
- Spaces
- Country code missing
Fix:
- Use CRM Support's phone number validation field
- Clean numbers via workflow → “Format Number” action
- Always store numbers with +CountryCode
6. WhatsApp Provider Issues: Twilio, 360Dialog, or Cloud API
CRM Support relies on external WhatsApp providers:
Common symptoms in CRM Support:
- Twilio WhatsApp API
- 360Dialog
- WhatsApp Cloud API (Meta)

- Workflow messages stuck at “Queued”
- Multiple reattempts fail instantly

7. WhatsApp Quality Score or Rate Limit Restrictions
WhatsApp monitors message quality across your business number.
If too many users:
CRM Support will show: Message failed — rate limit exceeded.
Fix:
If too many users:
- Block your number
- Mark messages as spam
- Do not respond
CRM Support will show: Message failed — rate limit exceeded.
Fix:
