Never email a dead address again.
A multi-layer verification engine checks every address before it ever leaves your outbox — so bounces stay low and your domain reputation stays high.
Multi-layer checks
Syntax, domain, MX record and live SMTP handshake — every address passes real checks, not guesses.
Protect reputation
Removing invalid and risky addresses before you send keeps bounce rates below provider thresholds.
Bulk + real-time
Clean an imported list in bulk, or verify on the fly as leads enter your workspace.
Seven signals, one verdict
Each address runs through independent layers and returns a single, confident verdict — valid, risky, or invalid — with the reason attached.
- Syntax & formatting validation
- Domain + MX record lookup
- Live SMTP mailbox probe
- Catch-all & role-account detection
- Disposable / spam-trap flags
Bounces are the fastest way to the spam folder
Mailbox providers watch your bounce rate closely. Verifying up front keeps you well under the danger zone and preserves the sender score your warmup worked to build.
- Keep hard bounces under 2%
- Stop wasting sends on dead inboxes
- Feed only deliverable leads into sequences
Questions, answered
How accurate is verification?
The SMTP-level probe confirms whether a mailbox actually accepts mail, giving industry-leading accuracy. Ambiguous mailboxes (catch-all) are clearly flagged as risky so you decide.
Can I verify an existing list?
Yes — upload a CSV and the bulk cleaner returns a scored, deduplicated list you can push straight into campaigns.
