Dear Maequee,

Thanks for the explanation.

When I tried to use your solution, I found out that the '/n' seperator does not work. As you may see from the below ss, in the concat_email column I see /n in text format. However, I want all different e-mails in the new lines. 

Could you please help me on this?
