Making the list

On a link's page, under Restrictions, choose Only allow certain emails.

A link's Restrictions tab, with the Only allow certain emails switch outlined.
  • List up to 500 addresses.
  • Allow a whole domain with *@example.com. That doesn't include its subdomains.
  • Each link has its own list.
The Only allow certain emails switch on, with a list of two addresses and one domain, and the box outlined.

What visitors see

Someone signed in with an address that isn't on the list can't fill out the form.

A form that only accepts responses from approved email addresses, with the Use a different email button outlined.
If your paid plan ends, a list you've already set keeps working and can be removed, but not changed until you upgrade again.
