Mail slots vs. Traditional Mailboxes

There are a few ways you can go about receiving mail including installing a mail slot to your door or setting up a traditional mailbox in front of your home. Both mailbox types must meet the U.S. Postal Service’s standards for mail to be successfully delivered.

Some homeowners prefer door slots for two reasons. First, they eliminate the need to exit the home as the mail is placed directly in the slot and into the home. A mail slot catcher can be placed on the interior side of the door to collect mail. Also, mail slots deter mail theft as passerby cannot reach into a slot and retrieve mail as one could with a mailbox.

Most mail slots are more affordable than traditional mailboxes – you can find them for under $20 at Lowe’s. Typically, mounting hardware is also included.

Instructions For Installing a Mail Slot

Installation of a mail slot isn't difficult. The tricky part is accurately cutting the slot where the hardware will be installed. It's likely the mail slot you purchase comes with a template on the package. If you find no template, use the measurements given in the instructions to create your own cardboard template.

Good to Know

Check with the local postmaster to make sure mail slots are suitable for your area. Your neighborhood or homeowners association may also have guidelines and requirements. Curbside mailboxes and drop boxes for parcels may be options as well.
