Great list, I’ve added some of those tools to my kit already! : )
On a side note, there’s one more tool you may want to add to the list: Contentools content marketing platform, an end-to-end software to help content managers and marketers manage all their content in one place.
I’m sure you’d like to check it out before considering it for the list, so here some links that may help you out:

Thanks for your time!
