We currently don't have email notifications for new Risks, Warnings or Notices; however, with the latest release of MyASUP (2.1); you can now receive customized risk, configuration and storage efficiency reports. From the company level, click on "Fitness Dashboard"; then click "Subscribe to Risks".
See section 7 on the release notes here: http://support.netapp.com/NOW/asuphome/MyAutoSupport_new.pdf
Hope this helps!
