Hi @asmecher and @NateWr One of our journals just published a new issue and right after that the editor also added an annoucement. Because the reply-to address for the notifications is set to the site admin, I am getting the responses from the registered users. These included:
Please stop sending spam.
Please my paper is not part of what you sent to me. Thank you.
Both of these users are old reviewers of that journal.
So I really think that making those two notification email's (new issue and annoucement) optional would be a good feature. I could do a pr, if you agree and point the right setting page where to put these.
