You buy a mailing list and assume it's ready to go. It's not. It needs processing — NCOA updates, address verification, deduplication, and formatting for presort.

Most list vendors hand you raw data and call it done. You're left figuring out the rest. Or worse, you mail it unprocessed and watch 25% of your pieces bounce because addresses are outdated, duplicated, or undeliverable.

We don't sell you raw data. We build, process, and deliver a mail-ready file. NCOA-processed. CASS-certified. Deduplicated. Presorted. Ready to print and mail the same day.

What We Process

NCOA Processing (National Change of Address)

Catches anyone who moved in the last 48 months and updates their address. The USPS requires NCOA processing for presorted mail. If you skip it, your mailing either gets rejected or you pay full postage.

What it does: Checks every address against the USPS move database and updates records for anyone who filed a change of address.

What it doesn't fix: Vacant homes, bad source data, people who didn't file official paperwork with USPS.

CASS Certification (Coding Accuracy Support System)

CASS is USPS software that verifies every address exists and formats it to postal standards. If an address doesn't match the USPS database, it gets flagged. If it's formatted wrong, we fix it.

Why it matters: This is how you qualify for automation postage discounts — which can reduce postage by 30–50%. Without CASS certification, you pay retail rates on every piece.

Deduplication

Identifying and removing duplicate records so you don't mail the same person twice. Sounds simple. It's not — names and addresses aren't always formatted the same way.

Bob Smith at 123 Main St and Robert Smith at 123 Main Street are the same person. Good deduplication software catches variations in names, abbreviations, and formatting.

Merge/Purge (Suppression)

If you have an existing customer list, we scrub it against the purchased list and remove matches. This keeps you from mailing current customers with prospect offers — which is both wasteful and annoying.

Example: You're mailing a "new customer discount" offer. We suppress your existing customers so they don't receive an offer meant for prospects.

Presort by ZIP Code

Sorting your list by ZIP code to qualify for bulk postage rates. On a 5,000-piece mailing, presort saves $400–$600 compared to retail postage. On larger mailings, it's thousands.

File Formatting

We deliver mail-ready files in Excel, CSV, or inkjet-ready format. If you're printing and mailing with us, we skip the file delivery and go straight to production.

Processing Your Own Customer List

You've been collecting customer emails and addresses for five years. You assume it's clean because it came from your own business. It's not.

People move. Businesses close. Email addresses change. Addresses get entered wrong. Over time, every list decays — even house files.

We run your customer list through NCOA and CASS before every mailing. Remove duplicates. Suppress unsubscribes and bounce-backs. Clean data drives better response and costs less to mail.

If you're only processing a list (not mailing), we charge $75 per 1,000 records. If you're printing and mailing with us, list processing is included.

What You Get Back

A spreadsheet (Excel or CSV) with these fields:

Full name
Street address (standardized to USPS format)
City, State, ZIP+4
Barcode assignment (for automation discounts)
NCOA move status (if applicable)
Deliverability score

If you're printing and mailing with us, we take that file and run it directly through our inkjet addressing system. You don't touch it. We just need your approval on the design and we're mailing.

If you're using the list elsewhere, we send you the file and you're done.

How Long Does Processing Take?

List counts & quotes: Same day (usually within a few hours)
Processing & file delivery: 24–48 hours after approval
For print-and-mail campaigns: Goes straight to production (no separate file delivery)

Processing Pricing

List Processing Only (No Mailing)

$75 per 1,000 records. Includes NCOA, CASS, deduplication, and file formatting.

Processing with Print & Mail

Included at no extra charge. All processing happens as part of the mailing workflow.

Merge/Purge Services

Combining multiple lists while removing duplicates. Pricing based on list sizes and complexity.

Why Professional Processing Matters

The most common budgeting mistake we see: skipping processing to save $40 per thousand, then losing $200 per thousand in wasted postage on undeliverable mail.

Real Example

A client bought a 10,000-piece consumer list for $800 and mailed it unprocessed. No NCOA. No CASS. No deduplication. 25% bounced. They spent $3,000 on printing and postage, and $750 of it never arrived. A processed list would have cost $400 extra but saved them $750 in waste. The "expensive" list just paid for itself five times over.

Professional processing does three things: it improves deliverability (fewer bounces), qualifies you for postage discounts (presort), and removes waste (deduplication). Most campaigns pay for themselves through postage savings alone.
