Make As Sure As You Can That The List You Select
Is Profitable - Test With Nth Selection!

When a mailing test is done, the user will usually request the Nth selection. This ensures that the test will include the effectiveness of the entire list, as opposed to segments.

"Nth Selection" refers to a number of names that are randomly selected by a computer from an entire list. Nth selection is like shuffling a deck of cards. Then you pick one of those cards randomly and test it out.

If you are unsure about your selection, test. Make sure you're never cheated by testing a randomly picked sampling of the list. That way, even though you do lose some money, that amount is minuscule compared to the amount you would have lost if you had mailed to the whole list.

Testing a small portion before sending your direct mailings to the whole list is how to make 100% sure that you never ever get cheated when you rent a mailing list!

A user should always use Nth selection because it prevents a broker or list owner from including loaded names. A user might rent the best list ever and get great results the first time around. But follow-up lists might be padded with names that will be less than appropriate. Without a Nth selection, a renter could only wonder what happened the second time around.
