Unlike most of the reports available in Wisetail, the Email Log Report cannot be permissioned to any Role other than a Super Admin. This is because the report contains a list of all email addresses that have been sent by your Wisetail site. This includes all addresses, even if an email profile field is set to private or invisible. It also includes all addresses sent to non-user email addresses.
Due to the sensitive nature of these contents, this report has been restricted to Super Admins due to privacy concerns.
