Let’s talk about how to keep your postage costs down.So far you have been following my advice and mailing to same list more than once. At some point you find lists that will produce returns continually, but you notice that you are receiving more returns than when you started mailing to those lists.
You may see things like "Undeliverable as Addressed" or "Forwarding Order Expired." Every time you mail to an address and that prospect has moved or cannot be found for any reason, you have just paid for postage with no possibility of getting a response.
Obviously it is a pretty big waste of money to continue to mail to this address, but what do you do about it? You could simply go into list of names that you have purchased and delete returns. No more bad addresses, no more wasted postage, right? That is one option but there is a better way to handle situation.
The US Postal Service has an NCOA (National Change of Address) System that a limited number of companies are licensed to access. These companies are able to take list that you have purchased, or compiled yourself, and check it against USPS system. You will receive a report that will let you know if anyone on your list has moved, gone out of business, or even if zip code that contact was in was changed by Post Office itself. Along with report you will receive a new copy of your list that has been cleaned and updated.
