Address List Cleanup
Turn a messy list into a mailable one.
What it does
Standardize a raw list to clean CSV, remove duplicates, or build household names, with low-confidence matches flagged rather than silently changed.
Why it matters
Lists arrive in every shape. Getting to a clean, standardized file is the step that makes everything downstream, from CASS to presort, actually work.
How to use it
- Upload the raw list
- Map the columns
- Download the standardized file
