Email event errors with:



The list of email addresses will need to be in a semicolon separated format and can be built in different ways (data fields, SmartObject call, item reference, etc.), but if there is an empty email address that results in leading/trailing semicolon; this will cause the email to error:                                                  -- works;               -- works;                                                 -- fails, trailing semicolon
;                                                                  -- fails, leading semicolon


Using an Inline Function > Text > Split will handle these erroneous use cases and allow for the successful sending of an email.
