How To Check The Given Email Field Value Is Present In The List Of Email Ids In Salesforce Workflow, Formula and Flows

The use case here is I want to check whether case email is available given in the list of email ids or not? If it's present in the list it will return true else it will return false.

IF(

   FIND(Your Email Filed,'test@gmail.com,man.6233@gmail.com,hello@haptik.co,

pk.kk@gmail.com,support@jugnoo.in,msj@gmail.com,mailer-daemon@amazonses.com,

sales@kks.com,l.dyj@licindia.com') > 0,TRUE,FALSE
 
 )

Example:

IF(
   FIND(SuppliedEMail,'test@gmail.com,man.6233@gmail.com,hello@haptik.co,
pk.kk@gmail.com,support@jugnoo.in,msj@gmail.com,mailer-daemon@amazonses.com,
sales@kks.com,l.dyj@licindia.com') > 0,TRUE,FALSE
 
 )
