Mailchimp sends the campaigns and knows who opened, clicked and unsubscribed. HubSpot holds the pipeline: contacts, companies, deals and the emails and sequences around them. The campaign report says a send performed well; the pipeline says nothing came of it. Both are true, because the two systems count different people and never compare notes.
Liaison reads Mailchimp and HubSpot together, matches the campaigns to the contacts, deals and sequences, and tells you which campaigns produced deals, which contacts are engaged but unowned, and who unsubscribed while a rep was still calling.
