We just got through finalizing our guest list and whatnot but there was a feature we thought that’d be interesting to add (assuming it isn’t already there and we missed it).
It’s easy to make mistakes when typing a ton of addresses, so to cross reference them with a service like USPS just to see if there are any mistakes (stretch goal if there was a way to “reconcile” the differences and update). I ended up exporting a guest list and writing a program to give me the changes and then I correct them myself, but I think it’d be a distinct and useful feature if it was integrated. Just my two cents haha
