I'm preparing a Validation letter to send to a collection agency and wonder if I should send it Certified/Return Receipt or just certified. The CA has a P.O. Box. How do they sign for it and what if they don't sign but just ignore it? Thanks.
Re: Return Receipt to a P.O. B I've gotten return receipts from P.O. boxes, but you can also send by Priority Mail with Delivery Confirmation for a grand total of $3.90 each.
