A direct mailing list is a file of verified postal addresses — for consumers or businesses — used to send physical mail such as postcards, letters, catalogs, and flyers. A quality direct mail list is CASS-certified (validated against USPS address data), deduplicated, and NCOA-processed to remove people who have moved, so your pieces reach real mailboxes instead of getting returned. The list can be targeted by the same attributes as any audience: demographics and income for consumers, or industry and company size for businesses.
Direct mail consistently outperforms digital channels on response rate because a physical piece commands attention a crowded inbox can’t.

CASS (Coding Accuracy Support System) certification means the addresses have been validated against official USPS data and standardized — correct formatting, verified ZIP+4. CASS-certified mail qualifies for USPS automation postage discounts and is far less likely to be returned as undeliverable.
NCOA (National Change of Address) processing updates your list against USPS move records so people who have relocated get their current address — or are removed. It protects your postage budget by cutting pieces that would otherwise be undeliverable.
Yes. Direct mail lists can be built for consumers (by age, income, homeownership, lifestyle, geography) or businesses (by industry, size, revenue, title), or a mix — whatever your campaign requires.
