Ask HN: How can I mail snailmail online cheaply? Receiving?

Even in $year I still have to send snailmail sometimes, and it's annoying having to buy stamps, print the PDF etc. What do y'all use to send snailmail which is easier? Also is there any service y'all would recommend about receiving snail mail that will open it and email me the contents? I'm using the USPS informed delivery which is nice, but have to call my fam to open and read it to me.
