Show List of Recipients Before E-mail is Sent Out

HI! I have had numerous occasions when I sent out an e-mail to a select group of people, but it ended up going out to a much larger group of people (which can be embarrassing). I was wondering if it is possible to list the recipients that will receive the e-mail BEFORE the e-mail is sent, rather than simply after it goes out. Or at least show the number of recipients that will receive the e-mail. I know that when I select the “People” tab and then select certain filters there is a list of people at the end of the page that meet that criteria. Is there any way to do something like that when sending out an e-mail from the plug-in?
