Mail to multiple recipients

Questions
1

I know about this method by looking at the Runway contact form

umbraco.library.SendMail(from, to, subject, body, isHTML)

But I need to send mail to multiple recipients. What's the best way to go about this? Will it work with a delimited list of addresses?

Thanks in advance.
