If inside the organization, SharePoint Online is part of the pool of tools used, it's super easy to bring Broadcast personalization to your site. It is started by generating or updating your Intranet Notifications & Personalization code.
In order to get your Cerkl Broadcast for SharePoint up and running, one of the ways to log into the platform is by getting the SharePoint Key, which is used to link your account and content in the Broadcast platform with the SharePoint app.

In case your intranet is not a Sharepoint one, don't worry, there is always the possibility for you to build a custom integration, that will allow your employees to receive corporate communications in that intranet.
