NCOA Check on Mailing Lists

[Raj Kumar]

I am starting a new mailing campaign with about 1000 post card every 2 weeks. I am buying the list from listsource and printing my cards. To keep the initial cost low, I want to mail these myself as its much cheaper this way vs. using click2mail. 

How can I do NCOA check on my entire list or make sure that the list if complaint with PostOffice address requirements ?

Please suggest...

Thank you so much in advance.
