How do they do the address to look like that? There's no label on there.
I'm sure they just run them through a printer that way. I didn't keep mine tho...
The mailing I did was over 20 years ago. We had seven women volunteer to address 5,000 envelopes each. Then they each drafted a master "dear friend" letter to match their handwriting. Then we had them printed.
We still didn't win.
