How to Automate Holiday Cards

I've been using some of these iCloud shared features that just came out the share and they're working fine. So we have a shared folder goes in there. And then I have on my Mac Hazel looking at that folder for anything with the name holiday in it. And then it processes it and puts it into a folder sorts it into a separate folder. That's great. I wish my family had done that. My parents have always kept the cards from the year and put them in a box with a Christmas tree. But having a scanned copy of those cards as well would be great. Not everybody's going to be around forever. And it's always nice to be able to live back.
