Processing Trade Show Lead Data
After a trade show, you typically have contacts from multiple sources: scanned badges (CSV export from lead retrieval tool), collected business cards (digitised via CamCard or similar), exhibitor directory downloads (HTML or PDF), event app exports and handwritten notes. Upload all these files to Email Extractor to extract and deduplicate email addresses into a single clean list. This is especially important because the same person often appears in multiple sources (they visited your booth, attended your session and were already in the exhibitor directory).
