There can be a number of reasons for this. Here are some examples of the reasons why recipients are not receiving the messages.
Example 1: Unapproved Display Name
The issue could be due to the phone number display name not being approved by Meta, causing message delivery to fail. To resolve this,
Check if the phone number display name is approved
- Go to Meta Business Console > WhatsApp Manager > Phone Numbers.
- Click on the relevant phone number and navigate to the Certificate section.
- If the display name is approved, it will be shown as below.
If the display name's approval status is Pending Approval/Rejected, contact Meta support.
This issue could be due to an incorrect placeholder format in the template message. If the placeholders are not in the correct sequence, the message validation may remove a value, causing delivery failure.
To resolve this,
- Check the placeholder order in your template message.
- The placeholders should be in sequential order (e.g., 1234567).
- If the order is incorrect (e.g., 7123456), recreate the template and ensure the correct sequence.
Things to remember for your message template to be approved
Your template name and message should clearly convey to the recipients why they have received the message.
