No Email Left Behind. Migrate your email to Google Apps!
The email supplied by hosting companies are convenient and easy to configure. This often makes them seem ideal when starting a new site. We simply add additional accounts, and the user simply logs into the provided webmail applications such as Horde, RoundCube or SquirrelMail, or configure Outlook or Thunderbird or some other client. This is a great and simple option, but becomes difficult to manage. After a while these can become cumbersome to manage and you may start to explore different options.
