INSIGHT

Single Brain Replaces Traditional Cold Email Team

  • Cold email operations used to require multiple specialists across sourcing, verification, warmup, copy, distribution, and optimization.
  • Eric Siu shows these tasks can now be orchestrated by agent-driven 'single brain' systems, collapsing weeks of work into an afternoon.
ANECDOTE

Agent Fleet Rewrites And Scores Sequences End To End

  • Eric narrates using OpenClaw + Instantly where agents review campaigns, rewrite sequences, and score until they reach quality thresholds.
  • He feeds successful 4% reply sequences from Google Drive, has agents rewrite, and recursive-score to 90+ before presenting for review.
ADVICE

Always Keep A Human In The Loop

  • Keep a human in the loop to provide taste and judgment rather than fully automating copy and decisions.
  • Eric insists humans must review agent outputs and approve changes before sending live campaigns.
