Email List Validator & Cleaner

Validate, de-risk, and dedupe a raw email list before you import it. Syntax plus heuristic checks (role, disposable, free, typos). This is not SMTP / mailbox verification, which needs a server.

🔒 Your list never leaves your browser. No upload, no server, no tracking.

Input

Drag a .csv / .tsv / .txt file here, or .

Lowercase the entire address (recommended for marketing dedupe) Gmail normalization: ignore dots and +tags in gmail.com local parts Strip +tags on all domains (treat user+tag@ as user@) Exclude role addresses (info@, sales@, ...) from the clean list Exclude disposable / temp-mail domains from the clean list Exclude free / consumer providers (for B2B lists)

Result

Paste or upload a list, then press Validate & clean.
