Frequently Asked Questions
How many pieces can I insert into my envelope?
As many as you want really, but you may pay higher postage if you go overweight. Our partners average 3 inserts plus the outer envelope. The biggest factor in deciding how many pieces you can insert is the final weight of the envelope plus all components. To qualify for the lowest postage rates, it needs to be 3.5 oz or less for Automated rates, and 4.0 oz or less for Enhanced Carrier Route rates.
How custom can I make my envelopes?
As custom as you want! You can choose your size, how many colors you want including full-bleed, messaging, and even a die-cut. We do it all in-house too! We’ll also make sure it meets USPS requirements.
Is there a minimum or maximum quantity I can print & mail with you?
Since we specialize in high-volume printing and mailing, jobs under 2,000 pieces may be charged minimums. For large quantities, there is no maximum!
