Report server e-mail delivery can deliver reports in the following way
Send a notification and a hyperlink to the generated report.
Send a notification in the Subject: line of an e-mail message. By default, the Subject: line in the subscription definition includes the following variables that are replaced by report-specific information when the subscription is processed:
@ReportName specifies the name of the report.
@ExecutionTime specifies when the report was executed.
You can combine these variables with static text or modify the text in the Subject: line for each subscription.
Send an embedded or attached report. The rendering format and browser determine whether the report is embedded or attached.
