While there are various project settings that Administrator can configure, there are a couple that are worth setting up when you first start using Consequence.
Go to https://consequence.app/settings/global ↗ (if you have an Enterprise account, it will be https://[your-subdomain].consequence.app/settings/global)
If set, this will require all registered users in your Consequence instance to have email addresses within one of the specified top-level domains (e.g. gmail.com). This provides additional security by ensuring that all your users have active email addresses within your organization.
