How work-share actually works

The USPS lets us do part of their work. They pay us to.

Most senders hand mail to USPS at retail. The Post Office picks it up, validates the address, sorts it from scratch, routes it through national distribution, and delivers. Every one of those steps costs them money.

A USPS work-share partner does the validation, the sorting, the barcoding, and the routing in advance, then drops the mail directly into a deeper network point (SCF, NDC) so USPS has less to do. The Post Office pays us back for that work as a discounted postage rate. We pass it on.

The discount compounds with volume. CASS-validated addresses unlock additional savings. NCOA-cleaned lists go deeper still. Intelligent Mail Barcode (IMb) tracking is included. EDDM coverage by carrier route is included. So is daily pickup and same-day induction in most markets.

Frequently asked

Mail, answered honestly.

What is USPS work-share, and why does it matter?

Work-share is a USPS program where qualified partners (like L5) pre-sort, barcode, and inject mail directly into deeper points in the USPS network. Because USPS does less work, they pass meaningful discounts back to us, and we pass those discounts to you. It's the cheapest way to send mail at volume in the US.

Do I need to be a huge sender to qualify?

No. Our work-share infrastructure handles batches as small as a few hundred pieces. The bigger your volume, the deeper the discount, but our minimums are designed to be reachable for mid-market direct-mail and statement-printing operations.

Can L5 handle First-Class, Marketing Mail, and Periodicals?

Yes. We process all major USPS mail classes: First-Class (letters and flats), Marketing Mail (formerly Standard), Periodicals, and Bound Printed Matter. We'll recommend the optimal class for each campaign based on speed, cost, and content rules.

How do you handle address quality and CASS / NCOA?

Every list runs through CASS-certified address validation and NCOA (National Change of Address) before we accept it for processing. This is required for the deepest USPS discounts, and it dramatically reduces undeliverable mail, which saves you on top of the postage savings.

What about IMb tracking and reporting?

Every piece is barcoded with the Intelligent Mail Barcode (IMb), giving you in-route tracking events as the mail moves through USPS. We report this back to you via dashboard or API, so you know when your mail is hitting mailboxes.

Can you handle Every Door Direct Mail (EDDM)?

Yes. We process EDDM Retail and EDDM BMEU campaigns with full geographic targeting by carrier route, and we coordinate drop-shipment to local post offices to maximize delivery speed.

Do you do mail printing too, or only postage?

Both. Our partner network handles digital and offset printing for direct mail, statements, and transactional mail, then routes directly into our presort operation. One vendor, one workflow.

How quickly can you onboard a new campaign?

For a standard direct-mail drop, we can have you in production within 5–7 business days from contract sign. For recurring transactional mail, plan on 2–4 weeks for full integration with your billing or statement system.
