Using Salesforce Filters and Operators in Reports
When creating custom reports in Salesforce, it is possible to use fields provided by the Match My Email managed package. Once can filter on these field values using the criteria and operators that are “standard” and already available in Salesforce. Even Users that do not install the package and upload messages as tasks or Enhanced Email objects will find it useful to know about the following reference pages to understand how operators such as “contains” or “equal or less than” or date values such as “Last Week” and “Last 7 Days” can be used in reports.
