There are two ways to have a report sent to multiple email addresses.
When running a report in Stark ID
The Static section of Stark ID can be used to send a report to multiple emails by selecting Email from the output options.

Once the email output has been selected, each of the emails needs to entered with a semicolon between them, ensuring there are no spaces.
Scheduling reports to multiple emails
When setting up a scheduled report let the Customer Support team know that you require the report to be sent to multiple recipients, and provide the email addresses you would like to be included.
