Very helpful in a pinch when you need to send mail from your phone!
I needed to send important legal documents by certified mail and didn't have access to a printer. PostalForm let me upload my PDF, preview exactly what would be mailed, and see the total cost before paying. I received tracking information, could see when USPS received the letter, and was able to confirm delivery. The whole process saved me a trip to the post office too, and I'd use it again!
