SQL Server Reporting Services (SSRS), when integrated into SharePoint 2013 enables reports to be sent to users via email. From the report click Manage Subscriptions.
On the following screen click Add Subscription. You can configure the report options and click OK to save.
If you’ve not configured SSRS you may receive an error in the Application Event log on the SharePoint server hosting the SSRS service application. This could take the form:
The Report Server Email extension failed to read its configuration settings from the rsreportserver.config configuration file. The extension is not available to users. (Application: SQL Server Reporting Services Service Application, CorrelationId: …)
The web page may also fail to load, with an error like the one below.
If you encounter this error, open the SQL Server Reporting Services Service Application from Central Administration. Next, open e-mail settings and configure the SMTP server. Finally, open Provision subscriptions and alerts, enter the appropriate account details and click Ok.

Thanks Richard. Very useful information. I have further requirement extended on this, where a SSRS report which is hosted on sharepoint 2013 which will have email delivery schedule set up on it and also to pick up the user parameters. Basically data driven report subscription and embed the report in the email body. What would be the best approach for this either writing through the application code(through webservie: ReportExecutionService) or can we setup by sharepoint/reporting services subscription wizard? Many thanks jyothi
