The biggest advantage of email hosted on the cloud is that you get to access your messages on the move. Be it through your mobile, laptop or desktop, as long as there is an internet connection - present almost anywhere / anytime these days - you can do business.
At the office, from the comfort of your home or in the flight on travel, access to your business email on the web is just an internet connection away. You can even configure other external POP email accounts and view them fom within Zoho webmail as separate modules, all from one place.
While you are in the process of getting addicted to Zoho webmail, you can continue to access Zoho Mail including Calendar, Tasks and Notes from within your current desktop client via POP or IMAP.
The ultra-light, smartphone-friendly HTML client allows for true mobility, delivering full-featured Zoho Mail to any mobile device with a decent browser. Or you can use the local email client on your mobile device to fetch mail using IMAP/POP or Zoho mobile sync.
