5 Highest Reviewed Wall Mount Mailboxes to Consider

There are a variety of wall mount mailboxes to choose from, and they each have their own benefits and drawbacks. Some mailboxes are considered limited-service mailboxes because they are designed only for incoming mail.

Alternatively, full-service mailboxes have a way, usually a red flag, to notify the postal worker that outgoing mail needs to be collected. When choosing a mailbox, consider where it will be mounted, features, style, and finish. Know your recurrent weather conditions. If rain and snow are frequent in the weather forecast, choose a mailbox with a tight-fitting lid and waterproof coating to help the mailbox last longer.

Other considerations include making the mailbox accessible, visible, and in close vicinity to the house. The postal delivery person should be able to see the box so they can easily drop off and retrieve mail. The flag feature on some mailboxes advises the postal person if there is outgoing mail that needs to be retrieved. Another useful feature is a newspaper holder, which is especially convenient if the box itself is on the smaller side.

Keep in mind the overall landscape of the home to choose a mailbox that will complement the home’s style. Will the mailbox be placed in stucco, bricks, or wood? Most mailboxes come with hardware, but additional hardware may need to be purchased depending on where it will be installed. Read about five of the top wall mount mailbox choices below.
