# The "AI SDR" Agent (Inbound)

Overview What It Is An AI-powered system that responds to inbound leads within minutes, engages in natural qualification conversation via email or chat, determines fit against ICP criteria, and either books meetings with sales or routes to appropriate nurture. Why It Matters Speed to lead is critical—responding within 5 minutes vs. 30 minutes increases qualification rates 21x. AI SDR enables instant response 24/7, ensuring no hot lead goes cold while waiting for human follow-up. Who It's For Companies with high inbound volume Teams with limited SDR capacity Organizations selling globally across time zones Growth teams optimizing lead conversion Preconditions Required Tools GPT-4/Claude API (conversation) HubSpot/Salesforce (CRM) Calendly/Chili Piper (booking) Clearbit/ZoomInfo (enrichment) n8n (orchestration) Required Fields/Properties Lead form fields (name, email, company) Qualification criteria (BANT or similar) Sales rep availability calendars Routing rules by segment/territory Definitions Required Qualified lead criteria Disqualification criteria Routing rules (which leads to which reps) Escalation triggers to human SDR Step-by-Step Workflow 1 Configure Instant Enrichment Goal: Gather context before first outreach Actions: Trigger enrichment on form submission Pull company data (size, industry, tech stack) Get contact data (title, LinkedIn, phone) Pre-score lead based on ICP fit Implementation Notes: Enrichment must complete in <30 seconds to enable fast response. Use waterfall enrichment (Clearbit → ZoomInfo → Apollo) to maximize coverage. 2 Build Qualification Conversation Agent Goal: Create AI that qualifies leads through natural dialogue Actions: Define qualification questions (BANT, MEDDIC, etc.) Build conversational qualification prompt Handle multi-turn conversations Extract structured qualification data Implementation Notes: Qualification should feel like helpful conversation, not interrogation. Lead with value, weave in questions naturally, adapt based on responses. 3 Implement Multi-Channel Response Goal: Enable AI to engage via email, chat, or SMS as appropriate Actions: Email response for demo requests Chat widget integration for website visitors SMS option for mobile leads Consistent AI personality across channels Implementation Notes: Match channel to lead preference. If they filled a form at 10pm, email. If they're on site now (chat widget), engage in real-time. 4 Create Smart Booking Flow Goal: Enable AI to book meetings based on routing rules Actions: Define routing rules (territory, segment, round-robin) Integrate with rep calendars Handle timezone detection Confirm and send calendar invites Implementation Notes: Route based on territory first, then segment specialization. If assigned rep has no availability in 3 days, fall back to round-robin. 5 Build Handoff to Human SDR Goal: Seamless transition when human needed Actions: Define human escalation triggers Create handoff summary for SDR Maintain conversation context Notify SDR with full context Implementation Notes: Human escalation for: enterprise leads, complex technical questions, competitor mentions, expressed frustration, or AI uncertainty >30%. 6 Configure Nurture Routing Goal: Appropriately handle leads that don't qualify for sales Actions: Define nurture criteria and segments Build nurture sequence assignment Enable re-qualification triggers Track nurture progression Implementation Notes: Not all inbounds are sales-ready. Route to appropriate nurture based on disqualification reason: timing → drip campaign, company size → SMB self-serve, etc. Templates Initial Response Email Copy Subject: Thanks for reaching out, {{first_name}}! Hi {{first_name}}, Thanks for your interest in {{product}} - I saw you're looking to {{inferred_goal}}.

A few quick questions to make sure I point you in the right direction: - What's prompting you to explore this now? - What tools are you currently using?

Use fallback data and respond immediately, enrich in background. Over-qualification: AI asks too many questions, feels like interrogation. Limit to 2-3 key questions, spread across messages. Wrong rep routing: Lead assigned to unavailable or wrong-fit rep. Add availability check and segment matching to routing. Troubleshooting Tips If meeting book rate is low, review qualification email tone For high escalation rate, expand AI's objection handling If leads complain about AI, add more natural language variation KPIs and Reporting KPIs to Track Speed to Lead: <5 minutes first response Qualification Rate: >30% of inbounds qualified Meeting Book Rate: >40% of qualified leads book Lead Satisfaction Score: >4.0 / 5.0 Suggested Dashboard Widgets Response Time Distribution: Histogram of time to first response Qualification Funnel: Inbound → Engaged → Qualified → Meeting → Opportunity AI vs Human Performance: Compare conversion rates AI-handled vs human Channel Mix: Inbound by source and AI performance per source
