Using a Messenger bot to support a curated email newsletter

I publish a weekly email with curated things to read (about 350 subscribers). For a while I have been thinking about how to use a Facebook Messenger bot to accompany this email newsletter without getting depended on Messenger as a distribution channel. What I've come up with is a weekly message sent through the bot which lists the 3 most clicked articles from the previous week's email. My hope is that this can act as an entry port to people who don't instantly want to sign up for yet another email - without cannibalizing the email subscribers nor without locking myself in to Facebook. Any thoughts on it or suggestions for how to improve it? I'm using chatfuel.com for the bot, which I am so far happy with as it doesn't require any coding (obviously, the bot doesn't become very intelligent - but that's not really the goal) Here is the bot: http://m.me/meshedsociety.com
