Preparing Real Estate Email Databases for Verification
When consolidating contact data from CRM platforms (Follow Up Boss, kvCORE, BoomTown, Chime -- typically CSV), MLS downloads, portal lead exports (Zillow, Realtor.com -- CSV), open house sign-in sheets (PDF, spreadsheet), transaction management platforms (Dotloop, SkySlope -- CSV), property management systems (AppFolio, Buildium -- CSV), title company contact lists, lender partner databases and past marketing campaign exports, upload the files to Email Extractor to extract and deduplicate email addresses across all sources. Real estate contacts accumulate across CRM, MLS, portal leads, transaction files and marketing platforms, and the same buyer who inquired through Zillow, signed in at an open house and was referred by a past client appears in three different systems, so deduplication before verification reduces verification costs and prevents duplicate outreach.
