Sendio 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
