Break the process into two main buckets: removing existing customers/prospects and enriching contact data. Use Clay to create a workflow that enriches personal and company data, excludes companies already in your CRM as customers or open opportunities, assigns leads to SDRs, and moves qualified leads to sales sequences. You can also build custom solutions using n8n that extract attendees from PDFs, check against your CRM, score accounts for ICP fit, find decision makers at top-tier accounts, and trigger follow-up actions. Post-upload filtering in HubSpot can handle customer removal if you have company data to match against.
