Google Mail has over 10 million business users and growing. Each user has 25GB of storage to minimise the need to delete email. Furthermore, there's powerful Google search functionality and email/IM threading. Instant messaging is embedded in Google Mail so you can respond to an email in real-time. Also, your Google Mail is available from any computer so you're no longer limited to answering email at your desk. Google Mail is simple to use, but not simplistic in its functionality, which means less time required for user training. You can also use Google Mail offline after enabling the offline feature in Google Mail Labs.
