Clean your email list
without handing it to a stranger's server.

• Syntax validation with the reason for every rejection
• Duplicates removed and counted; whitespace/case normalized
• Disposable domains split out; role accounts (info@, support@) flagged
• Typo suggestions (gmial.com → gmail.com?) — suggested, never auto-corrected into a different person

Seeded 12-row list: 7 clean addresses out, 1 duplicate removed, 2 invalid rejected with reasons, 1 disposable split out, role account and typo suggestion reported. Re-check: PASS.

Don't take our word for it. Below is the unedited output of ListClean Local running on a fully synthetic 20-row sample list (fictional names, reserved example domains — no real addresses). In: 20 rows. Out: 10 clean addresses, 2 duplicates removed, 1 empty row dropped, 5 invalid rejected with reasons, 2 disposable-domain addresses split out, 2 role accounts and 2 domain-typo suggestions reported. Re-check: PASS.

• Sample output — cleaned list (sample_cleaned.csv) — the 10 mail-ready addresses, ready to import
• Sample output — rejects with reasons (sample_rejects.csv) — every rejected or flagged address, and why
• Sample output — cleaning report (clean_report.md) — counts, role accounts, typo suggestions, and the re-check verdict
