For nonprofit Workspace, the hard part usually isn’t registration, it’s getting proper approval and keeping it stable long term.
A lot of people rush the setup and later lose access because verification, compliance, or admin structure wasn’t done properly.
If your goal is mainly outreach infrastructure, many people skip that headache and just use ready Google Workspace admin panels instead, either on rent or by buying the full panel with full control.
I have my own thread here if that route helps:

Feel free to DM me depending on whether you want nonprofit approval or just stable Workspace panels for sending.
