Back in 2007 I feel I was one of the first users (probably not) of the Google Apps and services made available for your own custom domain. I was starting to work in a technology team and I had my own TLD lying around so I just signed up for the free edition of Google Apps for your domain - as it was called back in the days.The whole service still exists and it is still very nice to offer things like GMail and Google Drive with your custom TLD at the center of it. But the service is now called G Suite and it is no longer available for free :-( - at least not for everyone - educators may still use it for free.As I can still use my edition of G Suite (or I still want to call it Google Apps for your domain) I want to know what limits I have to endure. As the paid version calculates your Google license fee by user. Also there are several editions (and I feel these editions and the available feature sets have changed frequently over the years).So I haven't found so many resources which can document the limits of my free legacy edition of G Suite.I have found this one article at wired: https://www.wired.com/2012/12/free-google-apps/They're essentially saying that Google stopped offering a free version of G Suite in 2012. And shortly before 2012 the free version offered: 10 free users.So this may be a safe bet - but I feel I signed up much earlier than 2012 and back then the limit was even more open like 100 users. Mhhhhh o well. Let's see.
