Every address checked in minutes, not days
Built for speed and scale. Quick Verification confirms deliverability on standard, catch-all and SEG-protected domains using advanced validation techniques — the whole list, in the time it takes to make coffee.

What happens in those minutes
Every address runs the full set in parallel. The catch-all probe and SEG detection are the two most tools skip — and the two that decide whether a "risky" address is real.
Syntax & domain
Malformed addresses and dead domains are rejected before anything hits the wire.
MX records
We confirm the domain is actually configured to receive mail at all.
SMTP handshake
A real conversation with the mail server, not a lookup against a stale list.
Catch-all probe
Where the server accepts everything, we determine whether the mailbox itself exists.
SEG detection
Secure email gateways are identified so their blanket accepts are not read as valid.
Role & disposable
info@, admin@ and throwaway domains are flagged so you can decide how to treat them.
When to reach for Deep instead
Quick resolves the overwhelming majority of a list. For the stubborn remainder — the addresses where even a catch-all probe cannot give a confident answer — Deep Verification sends real mail and watches how servers respond over 72 hours.
