What emails are sent to the mailbox defined as "Error Notification Email"?

e-NOTUM allows you to configure alerts in the event that errors occur in the management of notifications. These alerts can be sent via email or via integration.

In the Configuration > Organization section (point 5: Activity e-NOTUM) you can define an email address in the field: Error notification email.

Errors that occur in the notification life cycle (failed to register or deposit or expired) will be sent to this mailbox, as well as errors in sending status changes to integrated applications (if applicable).

This mailbox is customizable. If a specific address is not defined, by default, e-NOTUM sets it to the same address to which daily reports are sent.

Another option is to configure it via integration, also in the same section (under email notifications).
