How it works
From messy CSV to safe-to-send list
Three steps. Minutes, not days. Real verification — not just syntax checks.
1. Upload your list
CSV up to 100k+ contacts. We auto-detect the email column.
2. Deep verification
SMTP probe, MX records, catch-all, disposable, role-based, dedupe.
3. Get safety report
Cleaned CSV plus deliverability score so you know it's safe to send.
Real SMTP probing
We actually talk to mail servers — not just regex pattern matching.
Catch-all detection
Identify domains that accept every address so you don't get false positives.
Reputation-safe
Verification runs from our infrastructure, never your sending domain.
