You can share a report via the sharing options of a report: Edit sharing > Share settings
Who can you share with?
A report can only be shared with users from the same organization who have the permission 'View Reports' in Access Control.
Note that if people with only the ‘View reports’ permission enter Analytics, they will only be able to see the reports shared with them. People with the permission 'Manage Reports' already have access to all reports of your organization, but by sharing a report with them, they will be notified about it by email.
Email notifications
For recurring reports, if Notify for new editions is selected, emails will be sent for each report edition.
If KPIs are selected for KPI notifications and Notify for low KPI scores is selected, emails will be sent to that user if a selected KPI drops below the set limit.
CSV data
CSV data can be sent to registered users each time a new report edition is generated, by selecting Send CSV data for new editions.
CSV data can also be sent to (unregistered) e-mail addresses. The report is not shared, only the data.
