(37,648 posts)Certified is when you fill out that green card, require a signature for receipt, and the post office will send that signed green card back to you. Of course, you may not get the green card back. But the USPS should have a record of the certified mail, since it has a tracking # (you keep part of the green card with the tracking #, when you send it).
It costs several dollars to send a letter by certified mail. That's usu. what people use to send payments that must be verified that it was sent.
Still, when you're sending a payment, the vendor either gets a payment or not. That's all they know. They require payment by a certain date. They don't have to consider that the post office didn't get it to them on time. It's not their problem. They MAY let that slide, if you can show you sent it. But they don't have to.
