Never send to a dead email again
Multi-layer verification catches invalid, catch-all, and disposable addresses before you send.
Everything you need, built in
Email syntax validation
Catches typos, formatting errors, and malformed addresses before they cost you credits.
MX record check
Verifies the recipient's domain has valid mail servers configured and accepting mail.
SMTP verification
Connects to the mail server to confirm the specific mailbox exists and is active.
Catch-all detection
Identifies domains that accept all addresses — high bounce risk flagged before sending.
Disposable email filtering
Detects temporary and throwaway email addresses that will never convert.
Bounce prediction
ML-based scoring predicts bounce probability so you can set your own risk threshold.
Three steps. That's it.
Upload or pipeline leads
Import a CSV, connect your CRM, or let verified leads flow in from our discovery engine.
We verify every address
Six-layer verification runs on every email. Invalid, risky, and disposable addresses are flagged.
Only valid emails proceed
Clean, verified addresses move to your campaign. Bad emails never waste your credits.
Providers we orchestrate
We integrate the best tools so you don't have to manage them yourself.
