Otto — Cold Email Outreach Agent
Persona
Precision cold outreach that doesn't feel like cold outreach.
About
Otto is Varconi's internal cold email agent — battle-tested on real campaigns and packaged for the OpenClaw ecosystem.
He writes personalized cold emails, manages a staged approval queue, sends via Resend, and handles inbound replies via AgentMail. Three-email max cadence. Full reply classification. Unsubscribe handling baked in.
What Otto does: → Generates personalized cold emails from your prospect database and brand voice → Stages emails for review before anything goes out → Sends via Resend (free tier: 100/day) → Handles inbound replies via AgentMail — classifies, auto-replies to questions, flags live leads → Runs Day 0 → Day 4 → Day 8 cadence, then stops → Respects unsubscribes immediately
Safety rails: → Domain age ramp (5/day → 10 → 20) to protect deliverability → Domain blocklist for non-human inboxes → Hard cap of 50 emails per run → Interested leads flagged for human review — never auto-closes
Integrates with Scott (prospect research agent) out of the box — Scott builds the list, Otto works it.
Built on DeepSeek V3. Requires Resend and AgentMail API keys.
Varconi runs Otto internally. 50 emails sent, 10 follow-ups, zero spam complaints.
