The Email field in Cal.com’s booking questions supports domain-level restrictions, allowing you to control who can (or can’t) book time with you based on their email address.

​
Use Case

This is useful when:
  • You only want people from a specific company (e.g., @company.com) to book.
  • You want to exclude free/public domains like @gmail.com or @yahoo.com.
  • You’re running internal meetings and only want your organization’s members to access them.

​
How to Configure

Go to your Advanced settings of your Event type setup. Under **Booking questions, **find the Email field. Click on Editnext to the booking question, and you’ll see options to:
  • Require emails that contain (…)
  • Exclude emails that contain (…)
Simply use the fields to specify or exclude email domains for your specific use case. BrandBird 2025-06-17 13.40.02.png
