About Sender Address Verification (SAV)
Stop 100% of spam with zero false positives
Sender Address Verification (SAV)
is the best answer to the unwanted email problem.
SAV is based on the premise that all senders must announce
and authenticate themselves the first time they send a piece
of e-mail. Sendio is the only enterprise-level tool that
uses Sender Address Verification.
Experience has proven that trying to
decipher legitimate email from unwanted email (spam) through
filtering does not work, because spam filters are never 100%
effective. Therefore, Sender Address Verification technology
authenticates the sender, not the message. A sender is
identified by simply replying to a verification request
email. This validates that the message comes from a
legitimate address and is not machine-generated spam.
The sender authentication approach has
many benefits:
- SAV does not mistakenly block
legitimate email ("false positives")
- First-time senders receive an
immediate confirmation that their message has been
received
- Verification is required only once
per sender (not per message): SAV "knows" the sender for
all future messages
- SAV restores confidence in email as a
business tool because messages are not filtered
- The solution is painless to the
end-user: no more "bulk" or "quarantine" folders to
search through for legitimate email
- Because SAV does not try to decipher
each message, IT staff no longer have to maintain
heuristic or Bayesian filter "rules" to keep up with
ever-changing spam attacks
- If they choose, users may
pre-authenticate known email addresses, eliminating even
the simple one-time verification (think of this as
leaving your friends' names with the doorman)
- Legitimate machine-generated email is
easily authenticated (again, only once) by the user
