How to compare entered input emailaddresses and the api emailaddresses

Question

Requirement is I will be entering emailaddresses on UI and it will be passed to the integration and the integration will return the emailAddresses with GUIDs . If any emailaddress is missing from the response which we entered then it must show that emailaddress on UI. Suppose I have passed test@test.com and test2@test.com and In repsonsed I get only GUID of only one emailaddress then it has to show the 2nd emailaddress on the UI as invalid error . How Can I achieve it
