Postal Address Verification for Direct Mail Companies

In the Postal direct mail business, your margins are tight, and consequently, every undeliverable piece cuts directly into your profitability. So what’s the real cost when, for instance, fifteen percent of your mail comes back as undeliverable?

It’s wasted postage, wasted printing, and furthermore, wasted labor. It’s angry clients who paid for delivery and didn’t get it. Every returned piece represents pure loss;money spent with zero return. Moreover, in a business where margins are measured in pennies per piece, fifteen percent undeliverable mail can be the difference between profit and loss.

How long have you been dealing with the stress of high undeliverable rates? Your clients expect professional results. They expect their message to reach the intended recipients. However, when you’re working with their outdated mailing lists, you’re set up to fail before the mail even drops.

Think about the impact on your client relationships. When a client’s campaign underperforms because of poor deliverability, they don’t blame their list—they blame you. You’re the direct mail expert, and thus, you’re supposed to know how to maximize delivery. What does it do to your reputation when clients see high return rates on their campaigns?

And here’s the thing: undeliverable mail doesn’t just cost you money on that specific campaign. Instead, it damages your relationship with the postal service. High return rates can affect your postage discounts and your standing with USPS. What happens to your business if you lose access to bulk mail rates because of poor address quality?

Postal Address Verification Built for Direct Mail

Our address verification services are perfect for direct mail companies. We offer CASS-certified validation, NCOA processing, and in-depth standardization to get your mail delivered to the right spots every time.

What We Deliver

CASS Certification: We check your mailing lists using a USPS-approved system to make sure every address meets the postal requirements. This system flags any addresses that aren’t valid and updates the ones that are to match USPS specs.

NCOA Processing: We run your lists through the National Change of Address database. This updates addresses for people who have moved and flags ones that aren’t deliverable anymore. Your mail still gets to the right people, even if they’ve relocated.

Address Standardization: We format addresses to meet USPS standards, fixing abbreviations and adding ZIP+4 codes for good measure. Addresses that are standardized like this get the best postage rates and are more likely to be delivered right on time.

Duplicate Removal: We cut out duplicate addresses, which means you save on printing and postage, and your campaign results look even better.
