Adding multiple email addresses in the recipients section within my notification section

Can i put multiple email addresses in the recipients section within my notification "Provide Sender and Recipient Details" section of my "send us a message" form?

Yes, you can do that.

All you should do is separate each email with the comma and space.

email1, email2, email3

You can see more about it on this guide: Send Notifications to Multiple Recipients

Do let us know if you have any issues setting it up and we would be happy to assist.
