I find it very helpful that the total email address count on a list is visible when adding lists to an email. I would like to suggest that it carryover to the scheduled email page. The list name is present on that page already. If the email address count of the list, or lists, were visible to the right of the list name, it would be very helpful. It's just one more way, in addition to the list name, that I can verify that I have attached the correct list.
