We generally recommend that our clients use Google Apps for their company email. It’s a great way to get email @yourdomain.com without the hassle of running (and paying for) your own mail server.
Up until recently, Google allowed up to 100 user accounts (using Google Apps standard edition) without having to pay a cent.
However Google has recently decreased the standard edition user limit from 100 to 50 for any new Google Apps signups. Existing Google Apps accounts are unaffected by this change.
For those of you who are planning on setting up Google Apps for your domain, keep this new 50 user limit in mind. If you require more than 50 accounts, you will have to use Google’s premium edition.
