The company claims Treo Mail's integration with other core applications on Treo is a key advantage over other email devices and solutions. Web pages can be launched, phone numbers dialed, and emails addressed by clicking the corresponding information (URL, phone number or email address) that arrives in an email.

Treo Mail is available for a free 30-day trial at Handpsring's website in two versions -- the Internet Edition, which accesses POP3 Internet email accounts, and the Corporate Desktop Edition, for Microsoft Outlook/Exchange or Lotus Notes/Domino email accounts behind a corporate firewall. Following the trial period, Treo Mail customers pay on an annual subscription basis, $49.99 for the Internet Edition and $99.99 for the Corporate Edition. Existing Treo Mail customers can upgrade to Treo Mail 1.5 at no additional cost.
