About Sendio

Headquartered in Newport Beach, Calif., Sendio's spam blocking appliance stops all
corporate junk mail. Sendio was formed because, like you, we were tired of dealing with
junk mail and spam. We saw companies spending money and hours trying to block spam
with only limited success. Filters require constant management and monitoring and can
block legitimate email as easily as junk email. We set out to create an affordable spam
blocking solution that requires minimal maintenance, never blocks a legitimate email, and
does not require filters.

The result:
Sender Address Verification (SAV) technology. The only filter-free, 100% effective
enterprise anti-spam solution.
