BETA ALERT

WhatsApp is currently a Beta Feature. If you wish to try out the feature, reach out to support@moenage.com.

WhatsApp Message sending and delivery can fail for various reasons. Template is invalid or the user opt-in is not updated on side of Gupshup etc. Here are the most frequently occurring errors and their reasons

Internal Errors

There are few errors which are generated by our internal system while sending WhatsApp Messages:

Error Description
Personalization Failed Occurs when Message Personalization fails and No Fallback message was set. The system will not send the message to the user and will generate the Personalization Failed error.
Invalid Mobile Number Occurs when Mobile number field is Empty, None, N/A, undefined, null or 0 OR contains any unicode character OR Length is less than 4 OR mobile number is not convertible to E.164 format
Users removed due to Global Control Group Occurs when user is part of Global Control group and hence MoEngage didn't send any message to the user.
Rejected because of DND Occurs when user qualified for Event triggered message during your configured DND hours and hence MoEngage didn't send the message to the user.
Not sent due to campaign level min delay Occurs when user qualifies for two or messages from same campaign but message is not sent because of minimum delay settings in your campaign

BSP/WSP errors

Messages may fail to be delivered because of the errors recognized by your WhatsApp Service Provider as soon as MoEngage hands over a WhatsApp Messages to WSP to deliver to end user. You can read more about these errors in documentation provided by you WSP/BSP.

For Infobip, please refer to the documentation here.

For Gupshup, here is the list of errors (Please note that the list is not exhaustive. Please reach out to Gupshup Account Manager if you see exceptions and need more information)
