Updated October 3, 2024

Postal Presort software helps in-house or third-party mailing teams prepare bulk direct mailings faster and more efficiently for handoff to the post office. Similar to [address verification software](https://www.g2.com/categories/address-verification), these tools automate data cleaning to ensure physical addresses are up to date, no duplicate mailings are generated, and all produced address labels are standardized. Postal Presort software often utilizes powerful algorithms to catch nicknames, initials, and abbreviations that could otherwise be difficult for workers to catch, as well as to identify households for consolidating mail recipients. Once mailings have been cleansed for accurate data, these tools then automate presorting to ensure businesses receive the maximum postage discounts possible from post offices.

Additionally, postal presort software can assist with identifying mail specifications such as carrier routes and delivery points to maximize mail deliverability. Either directly or through integrations, they support printing for address labels, container tags, and any required postal paperworks and statements. Users can also create templates and save settings for future mailings.

To qualify for inclusion in the Postal Presort category, a product must:

- Provide data cleansing features to update and verify physical addresses
- Automate direct mail presorting in adherence to national postal standards, such as USPS CASS, SERP, NCOA, and USPS PAVE
- Support address label and container tag printing
