Buyer’s Guide

Buyer's Guide for Security Mail box

There are various things that you should look for when purchasing the best security mailbox. As your mailbox, mails, and parcels are valuable, so it is necessary to make sure that the product you are going to buy is capable enough to save your things from being stolen.


The size of the mailbox is the most important thing that you should look for. The height, width, and depth of the mailbox depend on your needs. They are available in different sizes so always select the one that can easily accommodate your incoming mails, parcels, envelopes, etc. If you receive the mails more frequently, then you should consider the mailbox that has a large capacity. Also, if you frequently travel then the large capacity mailboxes are ideal for you. On the other hand, prefer small-sized mailboxes if you get few mails in months.

Construction Material

The construction material of your mailbox must be well enough so that it can bear the hardness of all the weathers well. Always go for those materials that can prevent rusting and corrosion.

Some mailboxes are constructed with heavy-duty galvanized steel to make them tough and durable whereas some mailboxes come with stainless steel and aluminum body which are also durable. Also, some manufacturers prefer both the heavy-duty plastic and aluminum to construct the mailboxes.

But, it is best to go with galvanized steel. It is more durable as compared to other materials. Also, the powder-coated finish makes the mailboxes resistant to optimum weather.

Moreover, always check the other parts of the mailbox whether they are durable or not. All the hardware must be made from corrosion resistant materials. Always check the hinges as they must be of stainless steel. Furthermore, the doors must be rubber sealed to block the rainwater from entering into the mail compartments.


If your mailbox is of ideal dimensions and made up of good material but not the best in terms of security, then the dimensions and durability will never save your mailbox or mails from being stolen. The best mailbox is the one having a good security system that prevents fishing, prying, leveraged entry, and vandalism.

Therefore, before going to purchase the mailbox, its security measures must be checked and confirmed thoroughly.

In the above list, the mailboxes from MailBoss are best in terms of security. They are featured with the Mail Shield Technology, anti-pry latch locking mechanism and 12-disc wafer lock with laser cut keys. Also, the other mailboxes have pry-resistant lock bracket, incoming and outgoing doors with hidden locks, and the removable trap door for protecting the mails from theft.

Moreover, some mailboxes are featured with secured outgoing mail trays, but some come with the unsecured ones. So, as your incoming mails are valuable, you should also keep an eye on your outgoing mails.

In a nutshell, security is the main thing. So, always select the mailbox that is featured with an advanced security system.


Always select the mailbox that is easy to install or mount. Some manufacturers offer the mounting hardware, but there are some companies that don’t provide the hardware with the product. So, always make sure that there is installation hardware within the box.
