I had the same puzzling question, on how to post stuff to my blogs through Evernote. I am really into Evernote and have become a big fan of postach.io, where I created my first Evernote powered blog, 60KThoughs but I wanted something that I could write my posts in evernote and have them there as the source and post them on my other WP blogs. I tried IFTTT, cloudwork, but the one that seems to work better is Zapier. I was able to create a zap that posts to WP any new notes created within a specified notebook, with the tag published, same as pistachio does. the Zap I created is here. The only thing is that It doesn't update the content if you make a change afterwards in Evernote like postach.io does.
