### Hunter.io Bulk Feasibility for 2,000 Companies
- Free plan: **50 searches/month** → would take 40 months ❌
- Starter ($49/mo): **2,000 searches/month** → 1 month, but that's the ENTIRE monthly allotment
- Growth ($149/mo): **10,000 searches/month** → comfortable for our needs
- Business ($299/mo): **25,000 searches/month** → overkill
- **API supports bulk:** Use `/v2/domain-search` with domain parameter; can filter by `seniority=executive,senior` and `department=management`
- **Key limitation:** Hunter.io rarely returns phone numbers — emails only

- Excellent API for scripting bulk lookups
- We already have an API key and it works great
- 95% email accuracy
- Pair with free Apollo.io for maximum coverage

### 3. 🏆 Recommended Stack for Our Use Case
**Phase 1 — Free (~2 weeks):**
1. Sign up for **Apollo.io** free tier
2. Search for cold storage companies by industry + location
3. Filter contacts by title (CEO, GM, Operations, QA)
4. Export up to 10K emails for free
5. Use **Hunter.io free** (50 lookups) to fill gaps on specific domains

**Phase 2 — If gaps remain ($104-149 one-time):**
1. Upgrade **Hunter.io to Growth** for 1 month
2. Script API calls against remaining company domains
3. Use seniority/department filters to target decision-makers
4. Verify all emails through Hunter's verification endpoint

**Phase 3 — Phone numbers (optional, $39-99/mo):**

### 4. 💰 Estimated Total Cost

| Approach | Cost | Coverage |
|----------|------|----------|
| Free only (Apollo + Hunter free) | **$0** | ~80% of emails, minimal phones |
| Moderate (Apollo free + Hunter Growth 1mo) | **$104-149** | ~95% of emails, minimal phones |
| Full (above + SignalHire 1mo for phones) | **$143-188** | ~95% emails + ~350 phone numbers |
| Maximum (2 months of paid tools) | **$250-350** | Near-complete coverage |

### Key Insight
**Don't overspend.** Apollo.io's free tier + Hunter.io's API can likely get 80-90% of what we need for $0-149. The niche produce/cold storage industry means many smaller companies won't be in ANY database — you'll need to supplement with manual website scraping regardless.

### Hunter.io API Script Approach
```bash
# For each company domain, run:
curl -s "https://api.hunter.io/v2/domain-search?domain=COMPANY.com&seniority=executive,senior&department=management&api_key=YOUR_KEY"

# Or use company name if no domain:
curl -s "https://api.hunter.io/v2/domain-search?company=Stemilt%20Growers&api_key=YOUR_KEY"
```

Each call returns up to 10 contacts with names, titles, emails, LinkedIn URLs, and confidence scores. For 2,000 companies, that's 2,000 API calls = 2,000 credits = fits in Growth plan easily.
