Potential problem: With one recipient it seems all is good, there is no error in workflow, recipient is defined, but when I check it on gmail and click into the message it’s damaged (can’t click into it)
Maybe you should use the split function to handle and separate the email addresses. As for the attachment in the email, it was not possible to understand the problem very well. What type of file is it? What is its size?
