problem mail concept for multiple users

I'd like to make a concept in gmail trough integromat.

all of this seems to be working exept the importing of the email addresses. same issue with outlook when i created a button to make this happen in outlook. it takes all the email addresses out of the mail list in a composition table and glues everything together without a space between the mail addresses. wich result in not reconizing the seperate addresses.

Has annyone experienced the same? or know a solution?

Thanks in advance!
