Free email and instant messaging service

You@message.casa and You@im.message.casa

message.casa is a free, privacy-focused email and instant messaging service built on smolweb principles: lightweight, intentional, and respectful of your digital space.

Philosophy

In an era of unlimited storage and constant notifications, message.casa offers something different: deliberately constrained email and messaging services that encourage mindful communication. We believe limitations foster creativity and reduce digital clutter.
