# Notification placeholders

As you [**will read later**](https://ieg4.gitbook.io/onevu-digital-platform/enotifications/enotifications-ebilling/untitled/bulk-import-tool/file-column-mapping), eNotifications are generated based upon the import of a file, which lists the accounts/claims/references to send notifications to.&#x20;

But these files do not need to contain purely the indexing/key value to use they can contain multiple columns per account/claim etc. which can then be passed in the notification to enable a more personalised, intelligent notification to be sent.&#x20;

So your notification content could contain relevant messaging with data from the back office e.g.

“Your parking permit is due to expire on **@{PermitExpiryDate}.”**

With this automatically converting to the actual data in the file for the customer in question.
