How to Get Your Oncologist Email List in 3 Steps

Step 1: Search for Oncologists

Go to app.iblead.com/register and log in. Click "New Search" and select your target country (USA). Then:

• Filter by business type: Select "Oncology" or "Cancer Center"
• Filter by location: Choose specific states (California, Texas, New York) or search nationwide
• Filter by specialty: Medical oncologists, radiation oncologists, surgical oncologists, hematology-oncology

The interface shows you how many results match your filters in real-time. You see the count before you spend a single credit.

Step 2: Refine with Advanced Filters

This is where precision targeting happens:

• Google Rating: Target practices with < 4 stars (they need reputation help) or > 4.5 stars (they're successful, good for partnerships)
• Number of Reviews: Filter by 10-100 reviews (community practices) vs. 100+ reviews (large cancer centers)
• Has Email: Only show oncologists with verified email addresses
• Has Website: Target practices with active websites (more likely decision-makers)
• Technology Detected: Find practices using specific software (HubSpot, Salesforce, etc.)

Real example: Search for "Medical Oncologists in California with websites, 20+ Google reviews, and no HubSpot detected." You get a list of independent practices that are established but not yet using advanced CRM tools—perfect for selling them one.

Step 3: Export and Use

Click "Export" and select CSV format. The file downloads with all 14+ data points. Import directly into:

• Salesforce (automated field mapping)
• HubSpot (instant contact creation)
• Mailchimp (segment by specialty)
• Lemlist or Instantly (cold email campaigns)
• Google Sheets (manual CRM entry)

Total time: 3-5 minutes from search to export. No waiting. No API calls. No technical setup.

Real-World Use Cases: How Companies Use Oncologist Email Lists

Use Case 1: Pharmaceutical Company Launching New Cancer Drug

You work for a mid-size pharma company. Your company just got FDA approval for a new HER2-positive breast cancer treatment. You need to reach oncologists who treat breast cancer—fast—before competitors flood their inboxes.

What you do:

1. Search IBLead for "Medical Oncologists, USA" + filter by specialty tags for breast cancer focus
2. Export 2,000 oncologists across major metro areas (New York, Los Angeles, Chicago, Houston)
3. Segment by practice size: solo practitioners get one message, large cancer centers get another
4. Load into Lemlist and send personalized cold emails

Sample email:

Subject: FDA approval: [Drug Name] for HER2+ breast cancer

Hi Dr. [Name],

[Practice Name] treats an average of [X] breast cancer patients annually (based on your Google reviews).

Yesterday, the FDA approved [Drug Name] for HER2-positive advanced breast cancer. Phase III data showed 40% improvement in progression-free survival vs. [competitor drug].

We're hosting a 30-minute clinical overview on [date] for interested oncologists. No sales pitch—just the data.

[Link to registration]

Best, [Your name]

Result: 12-18% open rate (vs. 2-3% for cold calls). 3-5% click-through rate. 8-12 oncologists register for the call.

---

Use Case 2: Medical Device Company Selling Radiation Therapy Equipment

You sell radiation therapy equipment. These machines cost $2-5 million. You can't cold-call your way into a $5M deal.

What you do:

1. Search IBLead for "Radiation Oncologists, USA"
2. Filter by Google rating (4.5+ stars = established, successful practices with budget)
3. Filter by "Has Website" (they're tech-forward, more likely to adopt new equipment)
4. Export 500 practices in states with high cancer treatment volume (California, Texas, Florida, New York)
5. Research each practice's current equipment (sometimes visible in their photos or website)
6. Create a targeted outreach sequence

Sample email sequence:

Email 1 (Week 1):

Subject: New linear accelerator reduces treatment time by 35%

Hi Dr. [Name],

[Practice Name] operates [X] radiation therapy suites. Here's a case study from a similar-sized practice in [nearby state] that cut average treatment time from 45 minutes to 29 minutes using [equipment name].

The ROI? 12 months. Attached: detailed cost-benefit analysis.

---

Email 2 (Week 3):

Subject: [Practice Name] vs. national benchmarks (patient satisfaction)

Dr. [Name],

Your Google reviews mention wait times. We analyzed 500+ radiation oncology practices. The top 10% average 2.2 stars on "wait time." Your practice: [X stars].

Our equipment reduces bottlenecks. 15-minute demo call?

---

Email 3 (Week 5):

Subject: [Competitor practice] just upgraded to [equipment name]

Dr. [Name],

[Competitor practice in same metro area] installed [equipment name] last month. They're now offering same-day treatment slots.

Let's discuss how you can match their capabilities.

Result: 1-2 practices book demos per 500 outreach emails. Each demo has 15-20% close rate = $1-2M in annual revenue from a €44/month email list.

Use Case 3: Market Research: Oncology Practice Landscape Analysis

You work for a healthcare consulting firm. A client wants to understand the oncology practice landscape in the Northeast: how many solo practitioners vs. large groups? What's their average Google rating? Which practices are tech-forward?

What you do:

1. Search IBLead for "Oncologists, Northeast USA" (filter by states: NY, PA, NJ, MA, CT)
2. Export all results with Google ratings, review counts, website status, technology stack
3. Analyze in Excel/Sheets: - Solo practitioners (1 result per address) vs. group practices (multiple doctors at same address) - Average Google rating by state - % with active websites - % using specific CRM/EHR software - Geographic distribution

Sample findings:

• New York: 1,247 oncologists, 78% have websites, average rating 4.2 stars
• Solo practitioners: 34% of market (smaller budgets, slower adoption of new tech)
• Large cancer centers (10+ doctors): 12% of market (high budgets, faster adoption)
• Tech adoption: 23% use HubSpot, 41% use Salesforce, 18% have no CRM detected

Result: Client gets a $15K market analysis for the cost of a €44/month email list. You deliver insights in 2 days instead of 4 weeks of manual research.

Pricing: IBLead vs. Traditional Email List Providers

Here's the honest comparison:

Provider	10,000 Contacts	20,000 Contacts	Data Freshness	Specialty Filtering	Tech Detection	Cost per Contact
IBLead Starter	€44/month	€89/month	Monthly	✅ Yes	✅ Yes (160+ tech)	€0.0035

Buy 1,000 Contacts	€500 one-time	N/A	Unknown	❌ No	❌ No	€0.50

Why IBLead is cheaper:

1. You filter before buying. Traditional providers charge per contact. You export 10,000 and hope 2,000 are relevant. IBLead shows you the count first.

2. Data updates monthly. Traditional providers update quarterly or annually. You're not paying for outdated contacts.

3. 14+ data points included. Traditional lists give you name + email. IBLead gives you 14+ fields per contact—no extra cost.

4. No minimum purchase. Buy 500 contacts or 50,000. Your choice. Traditional providers often have 5,000+ minimums.

Real example: - Traditional provider: 10,000 oncologist emails = €179/month + you manually research which ones are relevant = 40+ hours of work - IBLead: Search, filter, export 2,000 highly relevant oncologists = €44/month + 30 minutes of work

IBLead saves you 39.5 hours and €64/month.

FAQ: Oncologist Email Lists

Q: How many oncologists are in the IBLead database?

27,475+ oncologists across all US specialties. That includes medical oncologists, radiation oncologists, surgical oncologists, hematology-oncology specialists, pediatric oncologists, and other cancer care specialists. The database updates monthly with new practices and updated contact information.

---

Q: Are these emails GDPR and CCPA compliant?

Yes. IBLead only extracts publicly available data from Google Maps and practice websites. These are business contact details that oncologists chose to publish. This is completely different from buying databases where you don't know the source.

For US outreach, you comply with CAN-SPAM (include unsubscribe link, honor opt-out requests). For EU outreach, you follow GDPR rules (legitimate interest for B2B sales). IBLead provides data legally. How you use it is your responsibility.

Pro tip: Always include an unsubscribe link in cold emails. It's legally required and improves your sender reputation.

---

Q: How fresh is the data compared to traditional email lists?

IBLead data updates monthly. Traditional providers update quarterly or annually. When Dr. Smith changes her email address or moves to a new practice, IBLead catches it within 30 days. Traditional providers might take 6-12 months.

The difference matters. A 6-month-old email address has a 15-25% bounce rate. A 30-day-old address has a 2-5% bounce rate.

Real impact: Send 1,000 emails. Traditional list = 150-250 bounces. IBLead = 20-50 bounces. That's 100-200 more successful deliveries per campaign.

---

Q: Can I filter by oncology specialty and location?

Yes, extensively. You can filter by:

• Specialty: Medical oncology, radiation oncology, surgical oncology, hematology-oncology, pediatric oncology
• Location: Specific state, city, metro area, or nationwide
• Practice type: Solo practitioners, group practices, cancer centers, academic medical centers
• Quality: Google rating, number of reviews, review recency
• Tech: Website platform, CRM tools, analytics, email services
• Verification: Email verified, website active, claimed Google profile

Example: "Medical oncologists in California with 4.0+ rating, active website, and no HubSpot detected" = 189 results.

---

Q: What's the deliverability rate for oncologist emails?

95%+ for emails extracted in the last 30 days. IBLead only includes contacts with verified email addresses. We check for:

• Email syntax validity (correct format)
• Domain validity (domain exists and accepts mail)
• Recent activity (email was active within last 30 days)

You won't get perfect 100% deliverability (some practices change emails without updating Google Maps), but 95%+ is industry-leading.

Comparison: - IBLead: 95%+ deliverability - Traditional lists: 75-85% deliverability (they include old/unverified addresses) - Buying random contact lists: 50-70% deliverability

---

Q: Can I integrate the oncologist list with my CRM?

Yes. IBLead exports CSV format that integrates with any CRM. Popular integrations:

• Salesforce: Import via Data Import Wizard
• HubSpot: Bulk import to Contacts
• Pipedrive: CSV import to Deals/People
• Lemlist: Direct CSV upload for cold email
• Instantly: CSV import for sequences
• Google Sheets: Paste directly, then sync to your CRM

Time to integrate: 5-10 minutes. No API required. No technical setup.

---

Q: What if I need oncologists in other countries?

IBLead covers 37 countries. Currently available:

• North America: USA, Canada, Mexico
• Europe: France, Germany, UK, Spain, Italy, Netherlands, Belgium, Switzerland, Austria
• Asia: Australia, New Zealand

If you need oncologists in a specific country, check app.iblead.com to see coverage. US coverage is the most complete (27,475+ oncologists).

How IBLead Compares to Building Your Own List

Some companies ask: "Why not just scrape Google Maps ourselves?"

Three reasons:

1. It's slower. Building a scraper takes 2-4 weeks of development. IBLead took us 18 months. You're paying for that work upfront.

2. Google blocks scrapers. If you scrape at scale, Google bans your IP. IBLead has legal, rate-limited access to Google data.

3. You need ongoing maintenance. Scrapers break when Google changes their HTML. IBLead maintains the database monthly. You don't have to.

Real cost analysis: - Hire a developer: $5,000-10,000 - Development time: 2-4 weeks - Maintenance: 10 hours/month = $2,000/month - Annual cost: $29,000+

vs.

• IBLead Starter: €44/month = $420/year
• Your time: 30 minutes/month = €449/month (if you value your time at $500/hour)
• Annual cost: $3,420

IBLead saves you $25,580/year and gets you results in 3 minutes instead of 4 weeks.
