Our marketing tech stack has grown significantly over the last two years. We are running separate platforms for user behavioral analytics, outbound email sequences, form enrichment and webinar hosting. all attempting to sync back into our primary CRM. The main issue we are facing is data inconsistency and duplicate records. A lead fills out a form with one email address, gets enriched via a third-party tool, attends a webinar under an alternate email address and suddenly we have three different contact records in our CRM with fragmented engagement history. Our sales reps are complaining that lead scoring is unreliable because activity data lives in different tool silos or takes hours to sync over. For those running a modern marketing stack alongside a central CRM, how are you handling identity resolution and deduplication?
