Restricting email domains on registration is frequently used when a company is running an internal staff event and they want to stop attendees from registering with a private email address.

All they need to do is specify the accepted email domain or domains and all others will be restricted.

Here is how it works.

1. Go into the main event admin screen and select Details and then Edit Details.

2. Scroll down to the Checkbox that says "Allow specified domains in emails"

3. If you want to restrict the domains, tick the box and then enter the domains that are allowed

4. If the registrant enters an email address that has a domain that is not allowed, the platform will stop them from registering.
