KNOW BEFORE
YOU SEND.
Clean bad emails out of your list before they become bounces. VXSentry checks every address and helps identify deliverable, invalid, risky, catch-all and uncertain emails before you launch your campaign.
ADDRESSES IDENTIFIED
BEFORE YOU SENT.
YOUR EMAIL LIST ISN'T AS
CLEAN AS YOU THINK.
Every campaign eventually comes down to one question:
WHICH OF THESE PEOPLE CAN I ACTUALLY EMAIL?
VXSentry helps answer that before you spend the send.

SERIOUS VERIFICATION UNDERNEATH.
FORMAT CHECK
Is the email address structured correctly?
DOMAIN CHECK
Does the domain exist?
MAIL ROUTING CHECK
Is the domain configured to receive email?
MAILBOX RESPONSE
When the receiving server permits it, does it indicate that the recipient can receive mail?
CATCH-ALL DETECTION
Does the domain appear to accept arbitrary addresses, making individual mailbox verification uncertain?
DISPOSABLE EMAIL DETECTION
Does the address appear to use a temporary or throwaway service?
ROLE ADDRESS DETECTION
Is it a general-purpose address such as sales@, info@ or support@?
RISK SIGNALS
Are there suspicious patterns or other signals that warrant caution?
SUPPRESSION INTELLIGENCE
Does the record match applicable suppression information already maintained by the platform?
All without sending an email to the recipient.
SIX ANSWERS.
NO GUESSING.
DELIVERABLE
Looks good.
Available checks indicate that the address is a reasonable candidate for sending.
UNDELIVERABLE
Leave it out.
The address failed verification or showed a clear delivery problem.
HIGH RISK
Think twice.
Strong risk indicators were detected.
RISKY
Use caution.
The record contains a warning that deserves review.
CATCH-ALL
Mailbox uncertain.
The domain appears to accept mail broadly, so the individual mailbox cannot be confirmed.
UNKNOWN
We won't guess.
The receiving system did not provide enough information for a reliable determination.
WE'D RATHER SAY "UNKNOWN" THAN PRETEND WE'RE CERTAIN.
Email verification has limits. Some providers intentionally hide mailbox information. VXSentry distinguishes uncertainty instead of disguising it as confidence.
