Result: Only users with @company.com or @subsidiary.org emails can register.
How can I block disposable/temporary email services?
Great for preventing spam and fake accounts:
- Set plugin to Blacklist Mode
- Import our pre-made list of 500+ known disposable email services
- Add common patterns: *.tk, *.ml, *temp*
- Monitor logs to identify new disposable services
- Update your blacklist regularly
Common disposable services blocked: 10minutemail.com, guerrillamail.com, tempmail.org, etc.
Can I limit registration to educational institutions only?
Perfect for academic platforms and student resources:
- Whitelist .edu domains:*.edu
- Include international academic domains:*.ac.uk, *.edu.au
- Add specific schools:harvard.edu, mit.edu

This ensures only verified students, faculty, and staff can access your educational content.
How do I set up different rules for different registration forms?
Advanced configuration for complex sites:
- Plugin-specific rules– Different settings for WooCommerce vs BuddyPress
- Form-based filtering– Custom rules per registration form
- User role targeting– Different restrictions for different user types
