Hi, it has been a while that I set it up but in summary, new customers in TB get identified in mautic. I had to create some fields in TB module configuration to achieve this.
I get to see the customer interactions and behaviours on the shop with the mautic pixel and of course the orders and carts. Also helps to create newsletters from mautic to TB customers. I also have a CMS blog, so I know what new and old customers are reading.
I also do a periodic dump into mautic with additional fields.
