This is nuts, Alex Guyot managed to chain 25 automated actions together in Drafts 3.0:
“ Previously, the maximum amount of actions I (or anyone, as far as I know) have been able to chain together, was five. I didn't think this was enough for my stress test of new versions of Drafts, so I decided to try to chain more. My goal was not greater numbers for the sake of having greater numbers. I wanted to put together a chain that would fire off an action for every single service that Drafts is connected to, as well as chaining to a variety of apps which support x-callback-url.”
He posted a video of the process in action, so head over there and watch it. I'm duly impressed.
