Buying Guide

A good mailbox keeps mail dry. It also lasts long. Choose one that fits your home.

I used a steel box for five years. It never rusted. I love how it kept my letters safe.

  • Material: Pick metal or plastic. Metal should be rust proof. Plastic should be strong.
  • Size & Capacity: Make sure it fits big envelopes. Check the inside space. Choose a size that fits your needs.
  • Mounting Type: Wall mount or post mount. Pick the one that works for your house. Easy to install is best.
  • Weather Seal: Look for a tight lid. A good seal stops rain. This keeps mail dry.
  • Lock & Security: A lock adds safety. Choose a simple key lock. It stops theft.
  • Roof Design: A sloped roof lets water run off. Flat roofs can hold water. Pick a roof that drains well.
  • USPS Compliance: Must fit standard mail size. Check the dimensions. It will work with the mail carrier.
  • Finish & Coating: Powder coat or galvanized. These stops rust. They keep the box looking new.
  • Price: Set a budget. Good boxes can be cheap or pricey. Find the best value for you.
  • Style & Color: Choose a look you like. Dark colors hide dirt. Simple designs match most homes.
