solution for SharePoint weekly digests?

[Ivan Unger]

Hi, does anyone know of a finished product/solution to configure (companywide) weekly (or other cycle) email digests that includes some stuff like:

• recently edited/created or popular SharePoint Pages
• popular documents for configured time frame

I'd be cool with this being limited to a preconfigured site collection (specifically an intranet), though I would prefer a personalized digest depending on users O365 Groups memberships.

I'm looking for SharePoint Online solution, not onPrem.

I'd suggest having a look at Sharegate as it provides reporting for SharePoint Online and may provide what you need.
Alternatively have a look in the TechNet Gallery as there would be PowerShell scripts that would probably do what you want.
