When I delete and relist closed auctions page by page I get a Mass Auction Notification just as always. However, if I use the new button to delete and relist all auctions which have closed I get individual notifications of relisting. This can mean over 100 individual emails. The new button was supposed to reduce the work involved in deleting and relisting but I spend more time deleting the individual emails than I do deleting and relisting page by page.
I know I can opt not to receive emails confirming new listings and relisted items but I think these are necessary to confirm that actions have happened. I just don't want hundreds of individual emails.
