Email security appliance maker Sendio has raised $3 million in a second round of funding. The Irvine, Calif. startup claims its platform completely eliminates spam and email threats without falsely identifying any valid messages as spam. The appliance combines Sendio's Silverlisting technology (which uses SMTP tests to determine the legitimacy of the sending email server) and Sender Address Verification to confirm the identity of first-time, unsolicited emailers.
The funding was led by Athenian Venture Partners, with participation from previous investors Vicente Capital Partners, Shepherd Ventures, and Momentum Venture Management.
