@jason_chernofsky Hi there! We have actually been trying to bring (physical) snail mail as a part of our services. Maybe not today but we definitely have plans on adding the capacity for us to send these as snail mail soon enough. Thank you for your kind words!
An exciting App!

@bonvisions Thank you so much! Please let us know if you have any feedback/suggestions or interesting ideas! We love hearing from people
@atik_hossain Lettre reminded me of a Chinese poem that said, 'In the past, time moved slowly. Carriages, horses, mails all moved slowly, so that a lifetime was just enough to love one person.' You've brought back the charm of 'slow socializing' with code. 📜✉️ Congrats!
Lettre.app brings a charming blend of nostalgia and tech ✉️💻. Digital handwritten letters and PenPals make communication feel more personal in a digital world.
This new platform offers a delightful twist on traditional letter-writing by combining the joys of digital collecting and pen-palling with a global community! Designed for an immersive experience on the iPad and now available on iPhones, it provides a unique way to connect with others through heartfelt, deliberate communication. I’m excited to see how it brings people together in such a personal and meaningful way in our digital age!
