yay, postcard apps! this is my space, too. there's something really fun about making an API call and then postcards shoot out the other side.
i like your site and the visual design, very simple and straightforward. at $3.99 it does seem rather expensive compared to other options out there (i have an idea on how much it costs you). also, having some actual pictures of what the cards look like on the website will surely help with conversion.
the first postcard app I built is Three Kind Words (https://threekindwords.com). it’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. the first two cards are unsigned, and the last one reveals who sent them. it’s meant to be a slow, kind surprise in the mail. we've sent over 250 cards so far.
my latest postcard app is Slow-Mo Rainbow (https://slowmorainbow.com). this one lets you send a rainbow in the mail, one postcard at a time. i just launched it last week and am still getting the rough edges worked out, but in the spirit of the thread, i'm sharing it here.
thanks for this genuine feedback, it's really helpful insight. i like your idea of pre-vetted words and imagine there is something i could do with an LLM to moderate user generated messages.

I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
