The Stats & History > Notification History section allows you to see what notifications have been sent to your customers.
You can see each event's name (e.g. Notification on expiry date), the template used (e.g. Renewal reminder on expiry date), the notification status, the domain, the recipient(s), the date the notification was sent, the name of the online store the service is managed in, and the product type. You can also view the notification itself using the View button.
