Hi everyone,

We are having a requirement to send an email automatically with an attachment containing summary of employee's elections when they submit their elections using any life event. We wanted to see if there is any action available through VBS on the Benefits enrollment summary page by means of which we can trigger an email notification containing the Benefits confirmation statement as an attachment to be sent to the employees.

Please let us know if someone has an idea of how to achieve this. Any other suggestions is also appreciated.
