Frequently Asked Questions

What is EDDM and how does it work?
Every Door Direct Mail (EDDM) is a USPS program that lets you send mail to every household on specific postal routes without a mailing list. You select target neighborhoods by ZIP code and demographics. Postage is about $0.23 per piece — significantly cheaper than first-class mail.
How much does a direct mail campaign cost?
Costs vary based on piece size, quantity, and postage. A typical EDDM campaign of 1,000 6.5x9 postcards costs approximately $550 to $750 including design, printing, and postage. We provide detailed quotes for every campaign.
Can you help me build a mailing list?
Yes. We provide targeted consumer and business mailing lists filtered by ZIP code, income, age, homeowner status, business type, and more. All lists are NCOA processed and CASS certified for accuracy.
What is the minimum quantity for direct mail?
EDDM requires a minimum of 200 pieces per carrier route. Traditional direct mail has no minimum, though pricing is most cost-effective at 500+ pieces.
How long does a direct mail campaign take?
Most campaigns go from concept to mailboxes in about one week. Rush campaigns can be completed in 3 to 4 business days.
