"Message Undeliverable" when sending template messages

When sending template messages to your contacts via Wati, you may see an error "Message Undeliverable" or #131026

The message may look like this -

Possible Reasons

This error may occur due to one of these reasons -

  • The recipient phone number is not a WhatsApp phone number
  • Recipient Phone Number has blocked your business
  • Recipient has not accepted WhatsApp's new Terms of Service and Privacy Policy.
  • Recipient using an old WhatsApp version; must use the following WhatsApp version or greater:
    • Android: 2.21.15.15
    • SMBA: 2.21.15.15
    • iOS: 2.21.170.4
    • SMBI: 2.21.170.4
    • KaiOS: 2.2130.10
    • Web: 2.2132.6
  • The message was not delivered to create a high quality user experience. WhatsApp imposes a max limit of marketing template messages that a contact can receive in a certain time across all businesses. You can read more about this here - Per-User Marketing Template Message Limits.

How to solve this?

Using a non-WhatsApp communication method, ask the WhatsApp user to:

  • Confirm that they can actually send a message to your WhatsApp business phone number.
  • Confirm that your WhatsApp business phone number is not in their list of blocked numbers (Settings > Privacy > Blocked or Blocked contacts).
  • Confirm that they have accepted WhatsApp's latest Terms of Service (Settings > Help, or Settings > Application information will prompt them to accept the latest terms/policies if they haven't done so already)
  • Update to the latest version of the WhatsApp client.
