Anonymous letters delivering cheerful surprises across Canada, USA & worldwide by email
unknownsender.ca is a creative project with one simple idea: sometimes the kindest letters feel a little more magical when they arrive anonymously.

Whether it’s encouragement during a difficult week, a playful surprise, or simply a quiet reminder that someone is thinking of them, our goal is to make everyday letters feel special again.
Each letter is thoughtfully created using themed templates inspired by friendly woodland offices, whimsical departments, gentle official notices, and cozy creature correspondence. Some are funny, some are comforting, and many are delightfully strange in the best possible way.
