Paste your email list
Drop emails directly into the text box — one per line, comma-separated, or copied straight from a spreadsheet. The app validates each entry in real time and removes duplicates automatically.
Only plain email addresses. Names, columns, or extra text will be flagged and blocked.
The Pipeline
Five stages. One pass.
Paste your email body and HamCut scores it as HAM, BORDERLINE, or SPAM. SPAM content is blocked before the job ever starts.
Identifies the email provider — Gmail, Outlook, Yahoo, and more — for every address in your list.
Checks whether the mailbox actually exists and can receive mail. Classifies each address as Valid, Catch-All, or Invalid.
Analyzes every address for risk signals and flags anything that could harm your sender reputation.
Sends a test email to a seed Gmail account and checks via IMAP exactly where it landed — Inbox, Promotions, Social, or Spam.
In one sentence
Give it your list + email content →
it tells you what's safe, what's a trap, and where you'll land.
