How to format multiple authors name, affiliation and email in a paper?
We had a similar complicated case in our paper. I'd suggest this as a good way to do it.

For your own case, add a comma after the braces, followed by your email. 

Here's how it would look like:

{Author.one, Author.two}@univ-one.edu, Author.three@univ-ten.edu


I am assuming your username tells the reader that it is yours (has your lastname, initials or so). Additionally, do your best to sort the emails such that they follow the same order of authors.
