Scaling this personalization from ten emails a day to hundreds requires automated research that feeds relevant data points into email templates without manual lookup.
Scavio provides the automated research layer for cold email personalization, searching Google, Reddit, and YouTube for prospect signals at $0.005/credit so every outbound email contains relevant, specific context.

Why Scavio Wins
- Multi-platform research generates unique personalization data for every prospect. Google for company news, Reddit for their actual discussions, YouTube for their content presence.
- At $0.005/credit, research for 1,000-email campaigns costs $5-15. Clay charges $134/mo minimum for similar multi-source enrichment.
- MCP-powered agents can research and draft personalized emails autonomously. Feed a prospect list, get back research summaries and personalized openers.
- Reddit data is a cold email differentiator. Referencing a prospect's specific Reddit post about their technical challenge demonstrates genuine research that templated personalization cannot replicate.
- Pairs with any sending platform. Use Scavio for research and Instantly or any SMTP tool for sending, keeping each layer best-in-class.
