MaxPresort OS takes a mailing list in and sends a documented, fully containerized mailing out. Here's what happens in between.

## Finds the deepest discount on every run

MaxPresort OS evaluates each record against every allowable sort level and places it in the finest one it qualifies for. You don't choose between a carrier route sort and a 5-digit sort. The software applies both, piece by piece, where the density supports it.

- **Classes:** First-Class Mail®, USPS Marketing Mail® and Package Services
- **Schemes:** Walk Sequence, Saturation, High Density, Carrier Route, Enhanced Line-of-Travel, 5-Digit and 3-Digit
- **Shapes:** letters, flats, machinable parcels and saturation mailers

## Containers built the way USPS wants them

Once pieces are sorted, MaxPresort OS assigns them to bundles, trays, sacks and pallets using USPS container rules, without anyone hand-counting trays on the floor. Service bureaus use this to [run high-volume client jobs](https://maxpresort.com/solutions/).

### Custom pallet sizes

Set pallet limits to match your equipment, your dock and USPS requirements.

### Co-palletization

Combine eligible mailings on shared pallets for deeper discounts and less handling.

## Every piece and container labeled for automation

### Intelligent Mail® barcodes

Generate an [Intelligent Mail barcode](https://postalpro.usps.com/mailing/intelligent-mail-barcode) (IMb) for each mail piece, for Basic and Full-Service mailings.

### Tray tags

Print Intelligent Mail tray labels that route trays correctly through processing.

### Container & pallet labels

Label every sack and pallet so it moves through USPS facilities without delays.

## Paperwork that backs up every discount you claim

A presort is only as good as its proof. MaxPresort OS produces the manifests and supporting reports for your mailing, and supports **Manifest Analysis and Certification (MAC) Batch** so the output can be verified. [Read about our USPS certifications](https://maxpresort.com/compliance/).

- Certified manifests generated with every job
- MAC Batch support for verifiable presort output
- Reports that match exactly what is in the trays

## Fits into the workflow you already run

### Any data source

Import lists and batch files from mainframe, PC or cloud-based systems.

### Address hygiene

Pair with CASS™-certified address correction, change-of-address updates and duplicate removal before you sort.

### Grows with you

Add mail classes, piece types or new workflows as your program expands.
