Why Scavio Wins
- The OP's plan — 'going the hyper specific and personalization route' — only works if research per prospect is fast and cheap. Manual research kills throughput; Scavio at $0.005-0.02/prospect makes it feasible.
- Per-prospect research is 1-3 calls: Scavio site:domain latest news + AI Overview on the company + Reddit signal. Output feeds an LLM to draft 1-2 specific opening lines.
- Sender brand matters less than warmup discipline. Both Instantly and Smartlead work fine at entry tier; the win is in research and warmup, not in the platform pick.
- Honest case for skipping research at the very start: first 50 sends to validate the niche before committing to research budget. Once reply rate signals product-market fit on a niche, layer on research.
- Per-month cost at scale: 1,000 prospects/mo × $0.01 research = $10 + $30 Scavio plan + $39 sender = $79 total. Sustainable for a hyper-niched agency where reply rate is the moat.
