@andreasduess This is the first I've heard of Nanagram.
It turns out there are several extremely similar products.
The only one I was aware of before I made this is smilepostcards.co - which is great and I was using. But I grew frustrated with it because I had to reenter everything with each postcard. I wanted similar functionality but with the ability to remember my recipients and send to multiple people.
Honestly, had I known there were similar products, I would still have made it because it was just a fun project, but I probably wouldn't have put it on producthunt.
