## Mailing use cases
- [Apology letter template for an estranged sibling or family member](https://postalform.com/relationship-letters/apology-letter-template-for-estranged-family-member.md): If you're carrying regret, it's tempting to overexplain. A letter helps you do the opposite: apologize clearly, take responsibility, and leave room for the other person to respond on their own timeline.
- [Boundary-setting letter template for a family member (with an invitation to reconnect)](https://postalform.com/relationship-letters/boundary-setting-letter-template-for-family-member.md): Sometimes the problem isn't that you never talked. It's that you talked in the same painful loop for years. A boundary letter is a way to change the container: clear limits, calm tone, and a path back to contact that doesn't require anyone to lose their dignity.
- [Contractor payment demand letter template](https://postalform.com/letters/contractor-payment-demand-letter-template.md): Use this template if you are a contractor requesting payment for services rendered.
