You have any of (a) a leading semi-colon, (b) a trailing semi-colon, or (c) multiple semi-colons in succession. For example, ;[email protected];;[email protected]; would have a total of 3 empty strings, which are not valid emails.

You can fix your code by checking for empty values.

Set<String> emails = new Set<String>(System.Label.GratisOrderServiceEmail.split(';'));
// Ignore blank values
