Automated real estate investor lead generation using MLS data is a four-component system: a data source (MLS API), a workflow automation layer (n8n), an email verification service (Hunter.io), and a sequenced email sending platform (Saleshandy). Each component has a specific role and the integration between them is what produces a fully automated pipeline from market signal to booked investor conversation.
Component 1 — MLS Data Access
The MLS API provides daily updates on active listings, including days on market, price history, property attributes, and listing agent contact information. Access requires either a direct MLS board agreement or a third-party aggregator license. The data pull is configured for specific geographic markets and filter criteria — DOM threshold, price range, year built, property type.
Component 2 — n8n Workflow
n8n runs on a schedule (every 2 to 3 days for most markets), queries the MLS API, applies filtering logic, deduplicates against prior outreach history in Supabase, passes agent emails to Hunter.io for verification, and creates verified contacts in Saleshandy with property-specific custom fields. The workflow takes approximately 15 to 30 minutes to run for a market producing 200 to 500 qualifying listings per pull.
Component 3 and 4 — Verification and Sending
Hunter.io verifies each agent email for deliverability before the contact is created in Saleshandy. Saleshandy's sequence engine distributes sending across multiple warmed sending accounts and delivers the property-specific personalized email to each agent. Positive replies are flagged for human follow-up. The full system with interactive demonstration is at omnionlinestrategies.com/real-estate-agent-outreach-machine.
