How to Add Cold Email to Your OpenClaw Agent (Step-by-Step)

OpenClaw agents can do a lot out of the box: browse the web, run code, search, write files. But cold email — actually finding leads, building sequences, and sending personalized outreach — requires connecting external services.

I built this integration for myself while running my $1M challenge. Now I've packaged it as a skill. This article is the full tutorial.

What you'll have by the end: An OpenClaw agent that can receive a command like "find 100 aesthetic clinic owners in the US and load them into my Saleshandy sequence" and execute it — autonomously, without you touching a browser.

What You Need Before Starting

You don't need all of these on day one. For testing, Apollo's free tier (50 credits/mo) and Saleshandy's 14-day free trial are enough to run your first sequence.

Step 1: Get Your API Keys

Step 2: Store Keys in Your OpenClaw Config

Add your API keys to your OpenClaw agent's environment. In your openclaw.json or via the OpenClaw settings:

{
  "env": {
    "APOLLO_API_KEY": "your-apollo-key-here",
    "SALESHANDY_API_KEY": "your-saleshandy-key-here"
  }
}

Or tell your agent directly in chat:

"Remember my Apollo API key: [key]. Store it in TOOLS.md and use it for all Apollo operations."

Your agent will write it to the TOOLS.md file in your workspace for future reference.

Step 3: Install the Cold Email Skill

The Cold Email Skill is a SKILL.md file that gives your OpenClaw agent step-by-step instructions for using Apollo and Saleshandy via API. When you buy the $9 Skill Pack, you get:

• The complete SKILL.md file to drop into your workspace
• Pre-built curl commands for every operation (search, enrich, import, activate)
• 3 proven cold email sequence templates with personalization variables
• A DNS setup checklist (SPF, DKIM, DMARC)
• A warmup timeline and health score guide

To install:

# Copy SKILL.md to your OpenClaw skills directory
cp cold-email-skill/SKILL.md ~/openclaw/workspace/skills/cold-email/SKILL.md

Your agent will automatically discover and use the skill when relevant tasks come up.

Step 4: Set Up Your Sending Infrastructure

This is the part that trips most people. Do it wrong and your emails go to spam before they're even read.

Buy a Sending Domain

Never send cold emails from your main domain. Buy a variation:

• yourcompany.com → buy getyourcompany.com or tryourcompany.com
• Cost: ~$12/yr on Namecheap or Cloudflare

Set Up DNS Records

Three records, all required. In your domain registrar's DNS settings:

SPF Record (TXT):

Name: @
Value: v=spf1 include:_spf.google.com ~all

DKIM Record (TXT):

Name: google._domainkey
Value: v=DKIM1; k=rsa; p=[key from Google Workspace admin]

DMARC Record (TXT):

Name: _dmarc
Value: v=DMARC1; p=quarantine; adkim=r; aspf=r;

Get the DKIM key from: Google Workspace Admin → Apps → Google Workspace → Gmail → Authenticate email. Generate a new record for your domain and copy the public key.

Create Google Workspace Sending Accounts

Start with 2-3 accounts. Each can safely send ~40-50 emails/day once warmed up.

• Use real-sounding names: sarah@getyourcompany.com, not sales1@getyourcompany.com
• Add a profile photo to each account (helps deliverability marginally)
• Connect them to Saleshandy immediately — warmup starts from day one

Step 5: Find Leads with Apollo

Tell your OpenClaw agent exactly what you want. For example:

"Use Apollo to find 200 aesthetic clinic owners in the United States. Filter for owners, founders, and CEOs. Enrich each one that has an email. Save the results to /workspace/leads/aesthetic-us.csv"

Your agent will call the Apollo API and handle the Search → Enrich flow:

# Step 1: Search for people
POST https://api.apollo.io/api/v1/mixed_people/api_search
{
  "q_organization_keyword_tags": ["aesthetic clinic", "med spa"],
  "person_titles": ["Owner", "Founder", "CEO"],
  "person_locations": ["United States"],
  "per_page": 100
}

# Step 2: Enrich each person with has_email: true
POST https://api.apollo.io/api/v1/people/match
{ "id": "apollo_person_id" }

Step 6: Create Your Sequence in Saleshandy

You can do this via the web UI or the API. Via the API (what your agent will use):

# Create a sequence
POST https://open-api.saleshandy.com/v1/sequences
Headers: x-api-key: YOUR_KEY
{
  "name": "Aesthetic Clinics US - April 2026",
  "schedules": [{
    "name": "Business Hours",
    "timezone": "America/New_York",
    "days": {"monday":true,"tuesday":true,"wednesday":true,"thursday":true,"friday":true},
    "startHour": "09:00",
    "endHour": "17:00"
  }]
}

Then create each step (email) in the sequence with your personalized copy. The skill pack includes 3 complete sequence templates ready to paste in.

Step 7: Import Your Leads

# Import prospects to a sequence step
POST https://open-api.saleshandy.com/v1/sequences/prospects/import-with-field-name
Headers: x-api-key: YOUR_KEY
{
  "prospectList": [
    {
      "First Name": "Sarah",
      "Last Name": "Johnson",
      "Email": "sarah@example.com",
      "Company": "Glow Aesthetics"
    }
  ],
  "stepId": "YOUR_STEP_ID",
  "verifyProspects": true,
  "conflictAction": "noUpdate"
}

Import in batches of 50. Your agent handles this automatically — give it the CSV and the stepId and it loops through the batch import.

Step 8: Warmup Period (Don't Skip This)

New email accounts have zero reputation. If you start sending immediately, you'll hit spam folders — or worse, get flagged for phishing.

Warmup timeline:

Saleshandy's warmup is automatic once you connect accounts. Just wait. Check health scores in the dashboard before activating.

The Full Agent Command Flow

Once everything is set up, here's what you can tell your OpenClaw agent:

"Find 100 US plastic surgeon owners on Apollo. Enrich them. Import into Saleshandy sequence 'Plastic Surgeons US - April'. Activate the sequence when health score hits 85."

The agent executes this in sequence — no browser, no manual steps. It comes back with a report: how many leads found, how many enriched, how many imported, current health score.

That's the goal. Cold email on autopilot.

What the $29 Playbook Adds

The Skill Pack ($9) gives you the technical setup. The Full Playbook ($29) adds:

• Targeting research methodology — how to identify the highest-intent niches for cold outreach
• 5 additional proven sequence templates (including the one that generated €5.7M for Edi from Dermacare)
• Reply handling workflows — how to respond to interested prospects automatically
• Deliverability troubleshooting guide — what to do when emails land in spam
• Scaling guide — how to go from 100 emails/day to 1,000 emails/day without hurting deliverability

Common Mistakes (I Made All of Them)

1. Sending from your main domain. If it gets flagged, your whole business email reputation is at risk.
2. Skipping warmup. My first test email landed in spam with a phishing warning. Don't be me.
3. Using generic emails. info@company.com goes to a receptionist who deletes it. Enrich for the decision-maker.
4. Sending 200 emails on day one. Start at 20/day and ramp up over 2 weeks.
5. Using AI-sounding copy. "I hope this finds you well." Nobody reads it. Write like a human with a story and real numbers.
