I'm actually surprised that the Government Departments do not have a service that takes care of these! They will fine Google but almost all of the government email IDs are Gmail.
I was one of those that distributed hundreds if not thousands of Gmail invites when it started. However, since 2010-ish, I left Gmail to be just for Newsletters, and the ones that I'm not serious about. I'm always reminded that a day will come when I will just have no access, lock out and be done with it.
I had used my name's domain and had used the web hosting provided email service and I felt nice using the likes of `webmaster@brajeshwar.com` (early 2000s). Then I got a shorter domain with our family domain and is, now, powered by Google Workspace (with a plan to move to the competitors soon before the yearly plan expires). I had so many domains under the Google Suite free version since its beta. I did upgraded my primary domain to the paid version, when I had few mail delivery issues so I can talk to a person and that was also the time I realize I cannot go back. That was almost/about 10 years ago.
