Way to Verify Valid US Addresses in Bulk?
I have a list of businesses from a database and am getting ready to send letters, the only problem is that when I sent some out in the past, some came back as undeliverable.
I know that I can go to the USPS (United States Postal Service) website and verify the addresses, one at a time, but who has that kind of time, lol.
Can anyone recommend a program or service that does this?
Thanks!
Matt
