Thank you for reaching out to the Constant Contact Community. It's my pleasure to assist you today. That is a great question! You'll actually want to create a new list with those 10 people on it, and then you'll choose that list when sending.
I hope this helps. Please let us know if there is anything else we can do for you. Thank you for choosing Constant Contact.
