Existing options didn't quite work for me. While Gmail lets you schedule emails, seeing those drafts every time was tempting, breaking the surprise. FutureMe has moved to a paid model, and most alternatives either lack encryption, feel limited, or don’t allow editing after scheduling.

So I built PSFutureMail.

It's a simple web app where you can write a letter and choose a delivery date anywhere from days to decades in the future. Letters are private and encrypted by default. You can edit or delete them at any time before delivery. Attachments are supported as well.

There's also an option to publish letters anonymously so that others can read them.

The core idea is to make it easy to write something to your future self in the best possible way.
