# Pre-Send Review

Review, configure, approve and send a system broadcast

After creating a Broadcast you can review the configuration. 

This is a good time to go over the broadcast details and confirm that the information entered is what you have intended. Broadcasts cannot be reversed once sent so ensure all the details are as intend.

{% hint style="success" %}
Tip: Take time to carefully review the broadcast configuration.

Sending a Broadcast with incorrect information could cause problems in a crisis scenario.

Consider using [Prepared Templates](/sentinel-documentation/spaces/mass-notification/prepared-templates.md) to carefully craft broadcast configurations well ahead of time.

### Broadcast Recipients

The Pre-Send review screen allows you to view and configure broadcast recipients.

The recipients showing are populated form the groups you can select when creating a broadcast.

You can add or remove the user / contact recipients here to suit your requirements.

Using the table filters you can find the recipients you want more efficiently.

### Broadcast Attachments

If you want the Broadcast recipients to receive attached files you can specify that in the Broadcast Attachments section. The available file list is populated from your [My Files](/sentinel-documentation/resources/my-files.md) area.

<div data-with-frame="true"><figure><img src="https://4177106735-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKJPykUSrsRewdKkgo9UK%2Fuploads%2FMeuuQYBmkjOTElKgn5gH%2FScreenshot%202025-12-16%20at%2012.40.59.png?alt=media&amp;token=c7b82988-cd66-4604-a742-dbc79f77610d" alt=""><figcaption></figcaption></figure></div>

The attached files will be available to all Broadcast recipients for a limited time via a temporary link they will receive as part of the Broadcast message.

{% hint style="info" %}
The length of time the link is available is by default 24 hours.&#x20;

You can increase or decrease this time to suit your security requirements.
{% endhint %}

### Approving and Sending

If you are not satisfied with some of the Broadcast you can edit the configuration.

Click on the 'edit' button from the top of the page and make the edits as required.
