How to address a group of people in a postcard?

Question

I'm trying to write a postcard to three friends of mine. They are a family and all live in the same house. Rather than just writing down one name I thought about including all of them. But how can I do this, I don't want to write "Dear ..." three times.

Thanks in advance for your help.
