We get a lot of mailgun temporary failures when we send out emails to 20+ authors. mailgun seems to be happy to requeue them so this might not be a serious issue but it still might be good to either drop the number of emails we send at a time (to 5 or so @chyhuang) or add some batching / queueing functionality to our contact author / send email logic that does this automatically.
We get a combination of 4.7.0 (too many connections error), and 4.7.1 (too much mail errors).
