AI SDR Skill

What AI SDRs Actually Do

AI SDRs automate the repetitive work of sales development:

• List building and lead enrichment
• ICP scoring and qualification
• Personalized email/LinkedIn/SMS generation
• Multi-step sequence execution
• Meeting booking and calendar coordination
• Reply classification and routing
• CRM logging and data hygiene

They do NOT replace humans at conversion points. The handoff model matters more than the automation model.

+-------------------------------+-------------+-------------+

Important: AI SDRs win on volume and cost. Human SDRs win on conversion quality and complex deal navigation. The best teams combine both.

Section 2: The 4-Week AI SDR Deployment Program

Week 1: Foundation (Signal Setup + List Building)

Day 1-2: ICP Definition and Signal Configuration

Define your ICP with scoring criteria:

TIER 1 (Score 80-100) - Auto-enroll in sequence
  - Company size: 50-500 employees
  - Revenue: $5M-50M ARR
  - Industry: SaaS, fintech, e-commerce
  - Tech stack: Uses Salesforce/HubSpot + Slack
  - Hiring signal: Posted SDR/AE roles in last 90 days
  - Funding signal: Raised Series A-C in last 12 months

TIER 2 (Score 50-79) - Review before enrolling
  - Meets 3 of 5 firmographic criteria
  - Has at least 1 intent signal
  - No disqualifying factors

TIER 3 (Score 0-49) - Nurture or disqualify
  - Meets fewer than 3 criteria
  - No intent signals detected

Day 3-4: Enrichment Waterfall Setup

Build a Clay table (or equivalent) with cascading data providers:

Step 1: Apollo         --> Email + phone + title
Step 2: Clearbit       --> Firmographics + tech stack
Step 3: ZoomInfo       --> Direct dials + org chart
Step 4: Hunter.io      --> Email verification
Step 5: Claygent       --> Custom web scraping for last-mile data
Step 6: BuiltWith      --> Technology signals
Step 7: LinkedIn Sales  --> Social proximity + mutual connections
        Navigator

Target: 80%+ email match rate across your ICP list. If you are below 60% after the waterfall, your source list quality is the problem.

Day 5: Build Initial Prospect List

• Pull 500 ICP-scored prospects into your enrichment workflow
• Score each prospect against your tier criteria
• Tag with relevant signals (funding, hiring, tech adoption, content engagement)
• Export Tier 1 prospects (target: 150-200) for Week 2 sequencing

Week 2: Content (Sequence Creation + Personalization)

Day 6-7: Persona-Based Email Variants

Create 3 email variants per buyer persona. Each variant needs:

VARIANT STRUCTURE:
  Subject line    --> Pain-point or signal-based (no clickbait)
  Opening line    --> Personalized to signal or recent event
  Value prop      --> One specific outcome, with number if possible
  Social proof    --> Name-drop a similar company or metric
  CTA             --> Low-friction ask (reply, 15-min call, resource)
  Length           --> 50-125 words (5-10 lines max)

Example persona matrix:

+------------------+--------------------+---------------------+--------------------+
| Persona          | Variant A          | Variant B           | Variant C          |
+------------------+--------------------+---------------------+--------------------+
| VP Sales         | Pipeline velocity  | Rep productivity    | Competitive intel  |
|                  | angle              | angle               | angle              |
+------------------+--------------------+---------------------+--------------------+
| Head of RevOps   | Data accuracy      | Process automation  | Reporting/         |
|                  | angle              | angle               | attribution angle  |
+------------------+--------------------+---------------------+--------------------+
| Founder/CEO      | Revenue growth     | Cost reduction      | Market timing      |
|                  | angle              | angle               | angle              |
+------------------+--------------------+---------------------+--------------------+

Day 8-9: AI Personalization Layer

For each prospect, generate a personalized opening line using:

• Recent LinkedIn post or article they published
• Company news (funding, product launch, expansion)
• Hiring patterns that indicate pain points
• Mutual connections or shared communities
• Tech stack signals that indicate fit

Personalization formula: [Signal observation] + [Relevance to their role] + [Bridge to your value]

Day 10: Conditional Branching Logic

Build sequences with conditional paths:

                    Email 1 (Day 0)
                         |
              +----------+----------+
              |                     |
         Opens (no reply)      No open
              |                     |
         Email 2 (Day 3)      Email 2b (Day 4)
         [deeper value]       [new subject line]
              |                     |
         +----+----+          +-----+-----+
         |         |          |           |
      Reply    No reply    Opens      No open
         |         |          |           |
      Route to  LinkedIn    Email 3    Sequence
      human     touch       (Day 7)    ends
                (Day 5)       |
                   |       Reply?
                Reply?        |
                   |     +----+----+
              +----+     |         |
              |    |   Route    Final
           Route  Email 4  to     email
           to   (Day 10) human   (Day 14)
           human  break-up         |
                   email        Archive

Week 3: Launch (Sending Infrastructure + Go-Live)

Day 11-12: Domain and Mailbox Setup

Infrastructure requirements:

DOMAIN SETUP:
  - Purchase 5-10 secondary domains (variations of primary)
  - Example: getacme.com, acmehq.io, tryacme.com, useacme.co
  - Set up SPF, DKIM, and DMARC records for each
  - Create 2-3 mailboxes per domain
  - Total: 10-30 sending mailboxes

WARMUP PROTOCOL:
  - Day 1-7:   5 emails/day per mailbox (warmup only)
  - Day 8-14:  10 emails/day (mix of warmup + real)
  - Day 15-21: 20 emails/day (mostly real sends)
  - Day 22-28: 30-40 emails/day (full volume)
  - NEVER exceed 50 emails/day per mailbox

Compliance requirements (2025+ enforcement):

• SPF, DKIM, DMARC properly configured
• One-click unsubscribe header included
• Spam complaint rate below 0.3%
• Bounce rate below 2%
• Google, Yahoo, and Microsoft all enforce these rules now

Day 13: Sending Platform Configuration

Choose your sending layer:

+-------------------+-------------------+-------------------+
| Feature           | Instantly         | Smartlead         |
+-------------------+-------------------+-------------------+
| Warmup network    | 4.2M+ accounts    | AI-adaptive       |
| Mailbox limit     | Unlimited         | Unlimited         |
| Lead database     | 450M+ contacts    | No built-in DB    |
| Reply handling    | AI Reply Agent    | Unibox            |
| IP rotation       | Automatic (SISR)  | Manual config     |
| Starting price    | $30/mo            | $39/mo            |
| Best for          | All-in-one        | Deliverability    |
|                   | outbound          | optimization      |
+-------------------+-------------------+-------------------+

Day 14-15: Soft Launch

• Launch to Tier 1 prospects only (100-150 contacts)
• Monitor deliverability metrics hourly for the first 24 hours
• Check inbox placement (use GlockApps or mail-tester.com)
• Watch for bounce rates above 2% and pause if triggered
• Target: 95%+ delivery rate before expanding volume

Week 4: Optimize (Measure + Iterate)

Day 16-18: A/B Testing Framework

Test one variable at a time:

PRIORITY TEST ORDER:
  1. Subject lines     --> Impact on open rate
  2. Opening lines     --> Impact on reply rate
  3. CTA type          --> Impact on positive reply rate
  4. Send timing       --> Impact on open + reply
  5. Sequence length   --> Impact on total conversion
  6. Personalization   --> Impact on reply sentiment
     depth

Minimum sample size: 100 sends per variant before drawing conclusions.

Day 19-20: Reply Sentiment Analysis

Classify all replies into categories:

POSITIVE (route to human immediately):
  - "Tell me more"
  - "Can you send details?"
  - "Let's set up a call"
  - Meeting booked via CTA

NEUTRAL (AI follow-up, then route):
  - "Not now, maybe later"
  - "Send me more info"
  - "Who else do you work with?"

NEGATIVE (remove from sequence):
  - "Not interested"
  - "Remove me"
  - "Wrong person"

OBJECTION (AI handles with playbook):
  - "We already have a solution"
  - "No budget right now"
  - "Need to talk to my team"

Day 21: ICP Scoring Adjustment

Review first 3 weeks of data and adjust:

• Which firmographic traits correlate with positive replies?
• Which signals predicted meetings booked?
• Which personas converted at the highest rate?
• Which Tier 2 prospects should be upgraded or downgraded?

Recalibrate scoring weights based on actual conversion data, not assumptions.

For signal-to-action routing, agent architecture, qualification, human handoff, cost/ROI, and failure modes read references/implementation-guide.md when designing or debugging an AI SDR deployment.

Examples

• User says: "Set up an AI SDR" → Result: Agent asks pipeline need, CRM, and budget; recommends platform (11x, Artisan, AiSDR) and 4-week program; outlines 30-second checklist (ICP, enrichment 80%+, 3 email variants, signal-to-action, sending, handoff, CRM, reply classification); sets speed-to-lead (P0 <5 min, reply handoff <5 min).
• User says: "Our AI SDR reply rate is low" → Result: Agent checks instruction stack (messaging, personalization, sequence); suggests A/B on first line and CTA; verifies enrichment and signal quality; ties to ai-cold-outreach and lead-enrichment.
• User says: "When to use AI SDR vs human SDR?" → Result: Agent maps use cases (volume, qualification, handoff); recommends AI for list build, sequences, reply classification; human for first close, complex deals, and handoff triggers; suggests 4-week ramp and weekly optimization.

Troubleshooting

• Low meeting conversion → Cause: Weak qualification or wrong handoff. Fix: Define qualification criteria and handoff triggers; ensure positive-reply-to-handoff <5 min; train on objection handling; review reply sentiment accuracy.
• Deliverability issues → Cause: Warmup, volume, or authentication. Fix: Run deliverability checklist (SPF, DKIM, DMARC, unsubscribe, bounce <2%, warmup 14–28d, <50/mailbox); test inbox placement (GlockApps, mail-tester).
• Tool swap didn't help → Cause: Instruction stack or context missing. Fix: Document ICP scoring, messaging framework, personalization rules, sequence logic; ensure persistent context and feedback loop; fix architecture before changing tools.

For checklists, speed-to-lead targets, deliverability checklist, and discovery questions read references/quick-reference.md.
