Founded in 2003, Sendio is a venture-backed, privately held company whose products protect the email environments of enterprises and institutions from attacks and abuse, and dramatically increases employee productivity by reducing the amount of time required to manage an email inbox. Using self-managing communities similar to those found in social networking applications, Sendio users receive all of the email sent by customers, suppliers, partners, friends, associates and other members of their “community” while being completely shielded from both nonsense messages sent by casual abusers and devious messages from malicious criminal concerns.
