Unless you want to get bombarded with constant notifications, it’s best to modify your SharePoint alerts in a way that suits you. This way you can get real-time updates or reports just the way you like them.
From inside your document folder or a document library, select the three ellipses in the top menu, then select “manage my alerts.”
Here, you can customize how you wish to receive your alerts (email or text notifications) and also when to receive them — like if someone modifies a document or creates a new file. You can also select instant alerts and a daily or weekly summary.
