Hide field based on entered email address

I would like to hide the payment module for ca 70 invited guests. Once they enter their email, the payment module should be hidden. How can I create a condition that checks their entry against the 70 emails?

If the email addresses that you want to allow are all under the same domain, then you can do it with only one condition, the condition should look like this: 

This will show the needed fields only if the entered email address is under the domain that you want, otherwise you will need to create one condition per email address.

However, you can provide us more details about the email addresses, if they are or not under the same domain or if there is something that these email addresses have in common that could help to simplify the process.

We will wait for your response.
