E-mail Notification to Multiple Users

Is there a way to send e-mail notification to multiple users? For example, I want to send an e-mail to myself, and an e-mail message to my two-way pager, in the event I am out of the office.

What is the syntax, if any, to send to multiple users? Is it a comma or semi-colon?

Will be added to the product roadmap to have an alternate email address next to the second one

Thank you for the info!!
