Thanks for this two! I didn't know them! about customer.io is something that i actually would prefer to avoid. And intercom.io is more similar to what i have in mind but with a wider use instead of more focused to one user. From what i've seen intercom is more to stalk you users. Instead i would like it to be a side feature and be more open to sending messages, maybe, all users. But anyway thanks! At least i know there seems to be some sort of interest in this kind of things!
