Check a purchased, scraped or inherited contact list before anyone builds a sequence on it. Use when a lead list, investor list, prospect file, CSV export or enriched dataset arrives, when someone says they bought a list or paid for data, before writing outbound copy or scoring rules against a file, and when a campaign is bouncing or the personalization is coming out wrong. Also use before quoting how many contacts a file contains.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auditing a contact list ```bash list-audit contacts.csv # the report list-audit contacts.csv --grades A,B # what counts as usable list-audit contacts.csv --json # for a pipeline ``` Columns are auto-detected, the file is read once, and nothing but counters is held, so a 200 MB file is fine. It takes about twenty seconds per million rows. ## The number on the invoice is not the number you have The row count is what the seller quotes and the only figure anyone repeats. It is almost never the number you can send to. The first audit this was built from: **1,039,715 rows sold, 81,460 actually usable, 7.8 percent.** The rest were organizations with no human attached, rows with no email, or graded junk. Report the usable number before anyone plans against the row count. Someone will have already said the big number out loud, and the longer that goes uncorrected the more work gets built on it. ## Grade plus an email is not a qualified contact The tool reports two tiers and the second is the real one. A row can carry an A grade, a working email and still be a name at gmail with no company, no title and …

How to install
mdr add calebnewtonusc/chewbacca/list-audit@sha256:66e551bf7b7c4349The line at the top of this page pins the label git:20260921.a54be33, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
