Cold email personalization at scale

Personalize outbound emails efficiently. Research (2-3 mins per prospect): 1. Recent LinkedIn post or company news. 2. Mutual connections. 3. Technology they use (BuiltWith, SimilarWeb). 4. Recent job postings (indicates growth/pain). Personalization tiers: High-value accounts (custom per person): '[Name], saw your post about hiring 3 SDRs. Are you also scaling your sales tech stack?' Medium-value (templated with custom first line): 'Noticed [company] is using [tool]. How is that working for [specific pain point]?' Low-value (segment-based): '[Industry] companies typically face [challenge]. Curious if you're experiencing this?' Tools: Phantombuster for data enrichment, ChatGPT for variation generation, Instantly/Lemlist for sending. Batching: research 50 prospects, write custom lines, plug into sequence. Track: personalized emails get 3-5x reply rate vs generic. Test different personalization levels to find ROI sweet spot.
