Understanding and Resolving WhatsApp Undelivered Message Errors
Common Causes of WhatsApp Undelivered Message Errors
When sending WhatsApp messages through your CRM, you may occasionally encounter an error indicating that a message was not delivered. This issue can arise due to several reasons, each requiring specific steps to resolve.
1. Phone Number Without WhatsApp
If the recipient's phone number does not have an active WhatsApp account, messages cannot be delivered. Verify that the contact's number is registered with WhatsApp using a reliable third-party verification tool.
2. Marketing Template Limit Reached
Meta enforces limits on the number of marketing template messages a user can receive from businesses within a specific timeframe. This restriction is designed to maintain engagement quality and is not specific to your business. If a recipient has already received the maximum allowed marketing messages, further attempts will fail.
3. Unaccepted WhatsApp Terms or Privacy Policy
The recipient may not have accepted the latest WhatsApp Terms of Service or Privacy Policy. Until they do, messages from businesses cannot be delivered.
4. Outdated WhatsApp Version
Recipients must use a supported version of WhatsApp. Minimum required versions include:
- Android: 2.21.15.15 or later
- iOS: 2.21.170.4 or later
- KaiOS: 2.2130.10 or later
- Web: 2.2132.6 or later
5. Recipient Blocked Your Number
If the recipient has blocked your business phone number, messages will not be delivered. You will need to establish communication through alternative channels.
Solutions to Resolve Undelivered Messages
Use Utility Templates
Consider sending utility templates instead of marketing templates, as utility messages are not subject to the same delivery limits.
Request Customer Initiation
Ask the customer to send a message to your business number first. Once they initiate the conversation, you can respond without facing template limits.
