History
Record List
After a message is sent from Template Messages or Session Chat, it appears on the History page. The list shows message content, valid targets, delivery rate, read rate, sending status, estimated cost, and sending time. You can search and filter by message content, time, sending number, recipient phone number or BSUID, sending status, sending method, and message type.
You can increase or decrease the number of filtered items by "expand" or "contract".
Message details
Open a message to view its content, recipient identifier, conversion funnel, and loss analysis. The recipient can be shown as a phone number or BSUID. If the page shows only the target's BSUID, the target has not shared their phone number with the business.
BSUID (Business-Scoped User ID) is a user identifier provided by WhatsApp to help businesses identify customers. See the official Meta documentation.

Conversion funnel
click export data to export the conversion funnel data. Each data has the following meanings:
- Plan : the number of initial sending targets provided by the enterprise.
- Targets: the final number of targets after platform filtering.
- Sent : The number of messages successfully submitted and sent to the target.
- Delivered : the number of messages that are successfully delivered to the user after they are sent.
- Read : The number of reads marked by the user after the message is delivered.
Loss Analysis
loss analysis allows you to filter by phase and display the causes of conversion failures based on the selected phase:
- Plan → Targets : the reason why the target is invalid
- Targets → Sent : The reason for the failure returned by the submission channel server (except that the target is invalid)
- Sent → Delivered: the reason for the failure returned by the delivery/non-delivery receipt
Deleting records
To delete a sending record, click "Delete" and confirm the operation again. Deleted records cannot be recovered, so proceed with caution.
History records are retained for 30 days by default. To extend the retention period, contact EngageLab Customer Service.
