FAQ

Mailer box questions.

Is there a minimum order for custom mailer boxes?

No. You can order as few as one box. Most brands start with 25 to 100 for a launch or PR send, then reorder in larger runs.

How long does it take?

Most orders are printed and ready 5–10 business days after you approve your proof. Ask about rush if you have a deadline.

Can you print the inside of the box?

Yes. We print full color on the outside, the inside, or both, so you can add a message or pattern that shows when the lid opens.

What if I don't have a design?

Send us your logo and we'll lay it out on the box and send a free digital proof. Nothing prints until you approve it.

Kraft or white?

Natural kraft gives an earthy, eco look. White makes colors pop. Both are sturdy 200# B-flute corrugated that ships safely.

How much do custom mailer boxes cost?

Price depends on size, quantity and how much you print. The price per box drops as quantity goes up, and our popular sizes are the most economical. Get a free quote or price any size instantly in our 3D designer.
