Jetpack Contact Form – Sending to multiple email addresses

My issue is that I know people are using my Jetpack Feedback form at http://gomersalstmarys.co.uk/contact-us/ but nobody is receiving email notifications about them. The only time I know when it has been used is by manually checking the Feedbacks Tab on the dashboard. Here are the settings for the form with emails removed to avoid spamming:

[contact-form subject="From Gomersal St. Mary\'s Web Site" to="***@edukirklees.net, ***@edukirklees.net, ***@edukirklees.net"] [contact-field label="Name" type="name" required="true" /] [contact-field label="Email" type="email" required="true" /] [contact-field label="Website" type="url" /] [contact-field label="Comment" type="textarea" required="true" /] [/contact-form]

Now, clearly I’ve tried comma separation with the emails. I remember using semi-colons too but to no avail. Is it possible?

If I can’t use Jetpack I’m open to other plugin ideas that will send to multiple email addresses as I need copies to three separate addresses.

Thanks in advance!
