Design Your Mailer Box Artwork With US

If you don’t have a mailer box design, don’t worry. Just share the images, text, and logo with us, and our designers will create a design for you from scratch. If you have a designer and want to create it yourself, we will provide you with a mailer box dieline template according to your box size, allowing you to create the design on that template.

Below are some design tips for mailer boxes if you want to create them yourself:

  • Use colors, fonts, and images that align with your brand to create a cohesive look across all your products.
  • Print essential elements such as your brand logo, the product name, and key features.
  • If you have products that are made with organic ingredients, then use a minimalist design on sustainable material.

Frequently Asked Questions

We’ve answered all the common questions you may have before ordering a custom box.

Can I order a single mailer box?

The minimum order limit is not applicable; you are free to order any number of boxes that you need.

Can I get the dieline template?

Yes, you can get the dieline template after placing the order.

What is your turnaround time?

We will start work on your order as soon as you finalize the quote. Our priority is to deliver it within 7 to 10 working days.

What is the difference between mailer and shipping boxes?

Mailer boxes are designed for lightweight items, often with customized branding, suitable for e-commerce. Shipping boxes are heavier, sturdier, and used for bulkier, heavier items during transit.

Are my boxes be shipped assembled?

Assembling your custom mailer boxes is your responsibility after receiving them because they are delivered unassembled.

Can items be shipped in a mailer box without external packaging?

Yes, because these boxes are sturdy enough to protect the product inside. But we recommend using some external packaging like a shipping box for further safety.

Which size mailer box should I choose for my product?

To allow room for packing materials such as bubble wrap and packing peanuts, measure your product and choose box dimensions that are slightly larger than it.

How do I know if my design is ready to print?

Our design team will review your design for errors like artwork resolution or blurriness, etc. If they find any issues in your design, they will inform you within the proof and help in resolving them. Please note that our team will not review grammar and spelling mistakes.

ECB is very easy to work with and delivered a high quality final product. This was top tier customer service and quality. We will continue to work with ECB.


Amazing company! Micheal helped me with my design and walked me through the entire process. The price was amazing everything exceeded my expectations. And it was super fast i received my tracking number and my boxes came two days later.

Natasha Dixon

I was very reluctant initially to do business after having a horrible experience with another box company. Victor and the design team were amazing and created a perfectly designed box for my candle line.

Ben Spungin

John was great to work with. Very patient with design emails and he and team helped elevate final design. End product is more than I expected. Thick cardboard, beautiful finish, easy right angle folding, and attached tape to seal top and bottom. It’s beautiful.

Danielle Brody

I've ordered custom a few boxes for a game from Elite. They're easy and fast to work with. They sent a few options, answered my questions, and helped when I had to adjust the size of the box. The product is high quality and looks very professional.

Chris Wood

Mike was great to work with on a really large project we had. Worked through any issues we had quickly and efficiently. Mike also made sure we had the boxes earlier than expected allowing us to make our deadline.
