I have the tedious task of emailing sales summaries to all 50 of our co-op artists every month. Is there a workflow to handle selecting all the rows in Numbers for each artist, and then associating that with the correct email address from my artists Group in Contacts and then Mailing it to them in Apple Mail? I've been looking at Automator and Services, but maybe I should dive into the Alfred Powerpack instead? Any opinions? Thanks for your time.
