Why Scavio Wins
- AEO agencies sell to specific verticals (dentists, lawyers, real estate, B2B SaaS). Hyper-niched openings driven by per-prospect research outperform generic templates by a wide margin.
- Scavio per-prospect research delivers in 1-3 calls: site:domain latest news + AI Overview on the company + Reddit signal. Output feeds an LLM to draft 1-2 specific opener lines.
- AEO is a fitting service for the same agencies running cold email — pitch tracking AI Overview citations and answer-engine visibility, which Scavio also helps the agency deliver.
- Honest about warmup: regardless of tool, sender domain warmup discipline (2-4 weeks) drives deliverability more than the platform pick.
- Per-month at scale: 1,000 prospects × $0.01 research = $10 + $39 sender + $30 Scavio plan = $79 total. Sustainable for AEO agencies where one signed client covers the stack.
