Currently, when passing dynamic lists from Iterable to Facebook, our match rates (60-65%) are fairly low by industry standards. I'm curious if this is just passing over email as a match field for Facebook to match on.

One way of improving our FB match rates would be to increase the number of profile attributes that are passed to Facebook to match on, listed here: https://www.facebook.com/business/help/2082575038703844?id=2469097953376494

Is it possible to add additional match fields to the Iterable sync in order to better improve match rates?
