Frequently asked questions
Questions people actually ask
Do I need to talk to anyone to try this?
No. The free true-margin calculator runs without an account, a card or a call.
What does it cost?
The free tier is free forever. Paid plans start at $5 per month.
Who is this actually for?
Travellers, grandparents, people in long-distance relationships, and anyone who wants to send something physical without owning a stamp.
What problem does it solve?
Physical mail from a person has become rare and therefore disproportionately meaningful, and almost nobody sends it because it requires a shop, a stamp, a pen and a postbox.
Why should I trust the result?
It is plain arithmetic on the numbers you put in, worked out in your browser. Change any input and every figure updates, so you can check each one yourself.
