As a user, I want to take a list of email addresses separated by semicolons and convert them into a list in Apex, so that I can easily perform set operations on them.
email1@example.com; email2@example.com; email1@example.com; email3@example.com will be added in a set
String emailString = 'email1@example.com; email2@example.com; email1@example.com; email3@example.com'; String[] emailAddresses= emailString .split(';');
