I sent out a WikiProject-wide newsletter before realizing that there were errors on the page that was sent. I corrected the errors on the page, but is there a way to rescind a MM and then resend it? Thanks for any help.

You can undo all the edits the delivery account made and resend it. Other than that, it's like sending an email - there's no practical way to unsend it.
Thanks for your reply; I don't think this is fixable, although in my early mass-messaging days I seem to remember someone (I forget who) helping me out of an oopsie with some kind of mass-reversion tool. Cheers!
