Marketing AI for online retail?

Is there a software that takes every bit of data from every marketing platform you're invested in-- google analytics, facebook analytics, website views/clicks, email and newsletter views/clicks, all your completed sales-- then can aggregate, slice and dice, look for patterns, and make recommendations on where/how to invest your marketing dollars, based on ROI?

e.g. - use this type of language with that demographic in google ads, but that type of language with this other demographic. Advertise to boomers on facebook and to millennials on instagram, but only in this set of zipcodes-- in this other set of zipcodes, forget instagram and only use facebook. Send pop up sale emails to this demographic at 11pm because they do their most compulsive online shopping at bedtime (lol, me). etc etc.

The only one I've heard of is Salesforce Einstein, but that seems mostly for B2B-- fewer customers with bigger price tags requiring a sales team, a pipeline, etc.

We're just trying to market items in our shop directly to consumers via ads and automatic emails, no sales team. Does anyone know a marketing AI or automation software that does that?
