Why is Spam Such a Big Problem?

Spam exploits a fundamental flaw in email technology. The Simple Mail Transport Protocol (SMTP) enables email to be sent anonymously. Spammers hide behind this veil of anonymity to flaunt the law and fill your inbox with unwanted commercial email. Filters attempt to recognize spam by analyzing message content. Sendio recognizes that spam is not a content problem: it is a Sender Address Verification (SAV) problem.

Spam Is Cheap to Generate

A spammer can send millions of email messages in minutes using an inexpensive, readily-available email server -- at pennies per message. To reach the same number of people would cost exponentially more by US Mail (and even more by phone). Moreover, those who hire the spammers are attracted by the fact that potential buyers are just a click away from a purchase.

Email Was Not Designed to Stop Spam

SMTP (Simple Mail Transfer Protocol), the underlying backbone of Internet messaging, provides no mechanism to verify the validity of the email sender, thus making it an anonymous transport mechanism. Spammers hide behind this anonymity, not worrying about an electronic "paper trail" or the consequences of breaking anti-spam laws.

Filter-based anti-spam Solutions Do Not Work Effectively

Today's anti-spam products are based upon first-generation technology that uses a set of rules that are designed to filter real email from spam. These filters do reduce the amount of spam in the inbox. Unfortunately, they also stop legitimate email from reaching the inbox - this is known as the "false positive problem". Filter-based products create a "bulk" (or "quarantine") folder where all the filtered spam goes - as well as any real messages that were mistakenly "junked."

Sender Address Verification (SAV) Solves the Spam Problem

Fortunately, there is a technology, Sender Address Verification (SAV), which takes an entirely different approach: rather than try to analyze each message, SAV performs a first time Sender Address Verification. If the sender is valid, the message is accepted. If the sender is not authentic, then spam does not get through. This approach is 100% effective against machine-generated spam and most importantly does not block any legitimate email. Most telling, from our experience, is that companies that have deployed SAV have enjoyed 100% satisfaction. The Sendio I.C.E. Box is sold with a money back guarantee and no customer has ever asked for a refund.
