Custom Mailer Box: A Strong Addition To Your Brand 

Every brand needs good packaging to mail their products as subscriptions, gifts, and for ecommerce purposes. Mailer box packaging is the best solution for these purposes. These boxes are often confused with shipping boxes, but there is a clear difference between them. 

Mailer boxes are used for the same purpose as shipping boxes. However, shipping boxes cannot be used for the same purposes as mailer boxes, except for traditional delivery. Custom mailer boxes are more in use and in demand by brands in the market. 

If you’re wondering, why? Customising mailer boxes and shipping the products in them is easier for brands than using simple shipping packaging. The use of custom mailer box packaging makes the delivery of gifts, special packages, and PR gifts hassle-free. 

So, now let’s dive into some creative ideas that will help make your brand delivery more effective. Keep reading and get inspired!

Ideas For Your Custom Mailer Box Packaging 

1. Branded Design (External)

The external part of your mailer packaging will be the first thing your customers will see. So, try keeping the design minimal, with a well-printed brand logo for recognition. But ensure that the colour of your packaging layout does not overwhelm the customers. The simpler, the better!

2. Personalised Printing (Internal)

In the internal part of your mailer boxes, you can add custom messages for your customers. These personalised messages add to the engaging and memorable unboxing experience. Moreover, these messages induce a sentimental value that may inspire repurchase and future recommendations by the recipients. 

3. Eco-friendly Packaging Materials  

The use of eco-friendly materials for your custom mailer box packaging will not only benefit your brand sales but also reputation. These materials may include Kraft mailers, soy-based inks, and disposable adhesives. Add a note about the materials used in your mailer packaging and watch your sales go boom!

4. Functional Security Elements 

Customise your mailer packaging boxes to add the custom security inserts in them. For example, fitted inserts, dividers, or sleeves can be used for maximum product protection. Add the extra touch of security to your boxes to ensure a safe product delivery. 

5. Limited-edition Themes

Designs related to themes and seasons lead to exciting collaborations and effective customer engagement. Using limited-edition seasonal mailer boxes helps attract more sales and partnerships. This technique also leads to customers increasing your traffic through sharing. 

6. Interactive Packaging 

In this modern market, what would customers love more than tech-powered packaging, right? So, you can offer them that in your mailer boxes by adding QR codes, RFID tags, and more. These codes can give access to special offers, discounts, tutorials, or anything engaging, boosting your brand engagement effectively.
