Checking one address at a time? Verify your whole list in one go.
Nine checks on every address
Each address runs through the same layered scan, from a simple format check all the way to a live conversation with the receiving mail server.
Syntax validation
Catches typos and malformed addresses before they ever cost you a send.
MX record lookup
Confirms the domain actually has mail servers configured to receive email.
Domain health
Verifies the domain resolves properly and is set up to accept mail.
Disposable detection
Flags throwaway inboxes built to disappear within minutes of signup.
Role account detection
Identifies shared inboxes like info@ and support@ that skew engagement.
Free provider detection
Tells you when an address is personal rather than a company domain.
Catch-all detection
Spots domains that accept everything, so you know when a result is unconfirmed.
Live mailbox check
Connects to the real mail server and asks whether that mailbox exists.
Bounce prediction
Combines every signal above into one clear verdict you can act on.
What each status means
The mailbox exists and is safe to send to.
The address doesn't exist, or the domain can't receive mail at all.
The domain accepts mail for any address, so this one mailbox stays unconfirmed.
A known temporary or throwaway email provider.
A shared inbox like info@ or support@ rather than a named person.
Format and domain look fine, but the mailbox itself could not be confirmed right now.
One bad list can cost you months
Sender reputation is slow to build and fast to lose. Here's the chain reaction a dirty list sets off.
Invalid emails bounce
Every bad address comes straight back as a hard bounce, a wasted send and a wasted opportunity.
Bounces trip the filters
Mailbox providers watch your bounce rate closely. A high one marks you as a likely spammer.
Reputation blocks delivery
Once your sender reputation drops, even your genuinely good emails stop reaching the inbox.
Clean lists fix all three
Verified lists mean better delivery, higher open rates and a lower cost per real lead.
