Through the use of various “IoT” (Internet of Things) services, including but not limited to, Zapier and IFTTT any level of automation is possible within a marketing arena.
There are social media integrations, blogging automation, even chat bot integrations to give access to your customer on so many varied layers and platforms these days.
Whilst I do like to automate as much as possible you cannot, and must not, eliminate the human side of your brand. You are the brands voice.
Automation is just a tool, after all.
