WHY IT MATTERS

Tabs will cover part of

your design — keep

key content away from

these areas. We’ll place

the tabs for you, just

share your layout early!

Custom marketing mail is seriously cool — but USPS

rules around flaps and closures can be tricky. Share

your creative ideas with us early so we can make sure

everything meets machinability standards and saves you

money at the same time.
