I like that it connects our email marketing with all other parts in my CRM system - Salesforce Marketing Cloud & Hubspot (which we also utilize).
It's easy enough they can be taught how best fit into your workflow/processes once you get started using them! Not much dislike here at this time but if anything there are some things about which i wish were different or easier than others when getting setup initially however after working wihit these products long term; those issues have been resolved as well so no big deal now anymore :) We've seen significant improvement since implementing livemapper from lead quality through engagement levels throughout sales funnel process flow within each stage across multiple campaigns over past year+.
