'Google employees can read your stuff'
Even if these clients are currently running their own e-mail server, employees at the local ISP could use DPI to read their stuff. Anything you send on the internet that isn't encrypted can be read by lots of different people at lots of different points. Unless the clients are currently encrypting their e-mails, I don't see any privacy reason not to use gmail.
