New Consumer Mobile Email Service Launched by SFR Quickly Reaches 150,000 Subscribers Using Critical Path's Memova Messaging Technology


SAN FRANCISCO - November 2, 2005 - Critical Path, Inc. (Nasdaq: CPTH), a
leading provider of messaging software and services, today announced
that SFR, Vodafone's French Network Operator, has reached 150,000 MMS
Mail subscribers in just four months since the launch of the new
consumer mobile email service this summer. SFR's MMS Mail service,
powered by Critical Path's Memova(TM) Messaging technology, has quickly
attracted subscribers by providing a simple, cost-effective way to send
and receive mobile email.

Despite market research indicating that consumers want mobile email, the
cost and complexity of existing solutions were limiting mass-market
adoption. Utilizing Memova Messaging technology, SFR is providing MMS
Mail - a consumer-oriented mobile email service that is affordable,
simple to set up and works on most any mass-market mobile phone.

"MMS Mail makes it easy for SFR subscribers to access email on the go
and send and receive multimedia-rich messages on our standard consumer
mobile phones," said Jean-François Caillard, Messaging Product Line
Director, SFR. "Critical Path's messaging technology has helped us
provide the kind of mobile email service the mass market wants at a
price consumers can afford and thus adoption rates have far exceeded our
expectations."

Critical Path's Memova Messaging technology powers the core messaging
service for SFR MMS Mail. For just 2.50 per month, MMS Mail subscribers
can specify, based on sender, which email messages they would like to
receive on their mobile phone and have messages from multiple ISP or Web
mail accounts pushed to their phone's inbox. The service works with any
MMS-enabled phone and alleviates the need for an expensive phone upgrade
or installation of complicated software on the handset.

"We've learned from our experience with operators worldwide that
ease-of-use and affordability are key to mass-market adoption, " said
Mike Serbinis, CTO, Critical Path. "The rapid growth of SFR's MMS Mail
is proving this to be true yet again. MMS Mail is a good example of how
a mobile email service that is easy to set up and use, has the right
price point, and gives subscribers the messages that matter can rapidly
attract subscribers. We are extremely pleased to be part of SFR's early
success with this service."

In addition to powering SFR's MMS Mail service with Memova(TM) Messaging,
Critical Path's Memova(TM) Mobile has been deployed by leading Indonesian
operator Indosat, and Critical Path is working with mobile operators
worldwide to deliver consumer mobile email and messaging services for
the mass market.
