To share directly via email, use the 'Invite' options.

To share publicly (with unlimited people), and to allow other people to copy and duplicate your template into their workspaces, you should choose to 'Share to web'.

Select the 'Allow duplicate as template' if you'd like others to be able to copy your template to their Notion pages.

Or else you can toggle this off and still share the template with other permissions.
