check recipients

Hi,
Is is possible to check the list of recipients before sending a campaign (I'm using syc services)?
I want to resent a campaing because I have new contacts, and exclude the recipients of the first campaign.
I expected less unique recipients, so I want to check whats wrong.
thanks in advance!
