❌ 3. Common WhatsApp Message Delivery Failures & Solutions​

⚠️ Invalid parameter​

  • Reason: The request included one or more unsupported, misspelled, or incorrectly formatted parameters.
  • Solution: Double-check that all parameters match the expected format and data type.

🧪 User's number is part of an experiment​

  • Reason: The message was not sent as part of an experiment. (Since June 14, 2023, about 1% of users will not receive marketing template messages unless a customer service window or marketing conversation is open.)
  • Solution: Contact the customer via non-WhatsApp methods and ask them to message you, allowing you to resend the message within the customer service window.

📭 Message Undeliverable​

  • Reason: Unable to deliver the message. Possible causes:
    • Recipient's phone number is not a valid WhatsApp number.
    • Recipient is in India and is being sent an authentication template (not supported for Indian users).
    • Recipient hasn't accepted the new Terms of Service and Privacy Policy.
    • Recipient is using an outdated version of WhatsApp.
  • Solution:
    • Confirm the recipient can send messages to your WhatsApp business number.
    • Ensure they've accepted the latest Terms of Service.
    • Ask them to update WhatsApp to the latest version.
    • Check if your number is blocked in their settings.

💳 Business eligibility payment issue​

  • Reason: There was an issue with the payment method related to your account.
  • Solution:
    • Check your billing setup in WhatsApp Business Account.
    • Ensure a payment account is attached, credit line is set, and account is active.
    • Resolve any currency/timezone issues or exceeded free tier limits.

📉 Meta Marketing Optimization​

  • Reason: Message not delivered to maintain healthy ecosystem and engagement standards (due to per-user delivery limits).
  • Solution:
    • Avoid retrying immediately. Retry after increasing time intervals.
    • Review Meta's "Per-User Marketing Template Message Limits" documentation.

🧰 How to Avoid the "Undeliverable" Issue​

  • Submit utility-based content under the "Utility" category for better delivery.
  • Ask customers to message your business first, then reply with a template.
  • Start with a small number of conversations to improve delivery rates.
  • Set up Click-to-WhatsApp Ads to engage customers.

❌ Something Went Wrong​

  • Reason: The recipient's number is blocked in the Whautomate platform.
  • Solution:
    • Edit the contact details and unblock the number to resume sending messages.

🔍 Other Reasons for Delivery Issues​

Some scenarios may cause a message to appear as "sent" but not "delivered." These include:

  • Customer offline for over 30 days (messages expire after 30 days).
  • Customer has blocked your business number.
  • Customer is in a restricted or sanctioned country.

By following these steps, you can improve the chances of successful message delivery and resolve common issues effectively.
