Very cool, thanks for sharing.
I’m not really sure where to go with our project. Each letter has a theme and contains multiple pieces of artwork, a copy of a handwritten note, and some type of call to action (e.g. send us your art, respond to a survey).
You can see the last letter we sent here: https://www.postedletter.com/letters/004
We had a dream to keep the letter free and fund it through donations, selling art, or a sponsorship. We could probably break even with donations, but that revenue strategy is going to keep the project really small.
So we’re thinking about charging per letter. Before we do that, I feel like we need to crystalize the identity of our brand and the product. We need to be able to tell potential subscribers what they are going to get.
