💳 Transparent Pricing Structure

We believe in 100% pricing transparency with zero monthly minimums and no hidden subscription lock-ins.

Input Mode	What You Provide	Pricing	Billing Model	Best For
Option A: Names & Domains (Recommended)	First Name + Last Name + Company Domain / Website (via CSV, Google Sheet, or Text)	$5.00 per 1,000 verified emails found ($0.005 / result)	Pay-Per-Result (Unfound leads = $0.00)	Fast, scalable outbound. Highest ROI. Saves 75%–95% vs Hunter/Apollo.
Option B: LinkedIn Profile URLs	https://www.linkedin.com/in/... profile links	$10.00 per 1,000 profiles processed ($0.01 / profile)	Pay-Per-Processed (Scrapes profile + finds email)	When you only have LinkedIn URLs and need automated profile data extraction without cookies.

⚠️ Important Notice Regarding LinkedIn URL Enrichment

[!IMPORTANT] Why does LinkedIn profile enrichment cost $10/1k processed instead of $5/1k?
Scraping LinkedIn profile URLs requires enterprise residential proxy networks and anti-bot cloud browser clusters to extract the person's current company and full name without compromising your personal LinkedIn account.
💡 Pro-Tip to Cut Costs by 50%: If you export leads from Apollo, Google Maps, Crunchbase, or your CRM, your export already contains the lead's Name and Company Website. Use Option A to find emails at just $5 per 1,000 emails found, completely eliminating the LinkedIn scraping fee!

[Verified High-Confidence Deliverable Work Email ✅]

1. Intelligent Permutations: Generates standard corporate email formats tailored to business naming conventions.
2. DNS & MX Routing: Identifies host mail servers (Google Workspace, Microsoft 365, Proofpoint, Mimecast, etc.).
3. Catch-All Assessment: Detects whether the domain accepts all emails regardless of mailbox existence.
4. Direct Handshake (RCPT TO): Probes the mail exchanger to check if the specific inbox accepts mail without sending an actual email.
5. Safe Pay-Per-Result: Emits the valid deliverable email and preserves your lead metadata.

📥 Input Options & Configuration

Option 1: CSV / Google Sheets (Fastest & Recommended)

Pass a direct link to any public Google Sheet or CSV URL. The Actor intelligently auto-detects common column headers:

• Name Columns: name, full_name, First Name, Last Name, Lead Name, contact_name
• Company Domain Columns: domain, website, company_domain, Url, company website
• LinkedIn Columns (Optional): linkedin_url, linkedin, profile_url

{
  "csvUrl": "https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID/export?format=csv",
  "concurrency": 10
}

(You can also paste the standard /edit Google Sheets URL — the Actor auto-converts it to a CSV download stream!)

Option 2: Manual Names & Domains

Paste contacts directly into the input array in the format FirstName,LastName,domain.com:

{
  "manualInputs": [
    "Satya,Nadella,microsoft.com",
    "Sam,Altman,openai.com",
    "Marc,Benioff,salesforce.com",
    "Brian,Chesky,airbnb.com"
  ],
  "concurrency": 10
}

Option 3: LinkedIn Profile URLs

Provide a list of public LinkedIn profile URLs. The Actor automatically extracts their full name and current company domain:

{
  "linkedinUrls": [
    "https://www.linkedin.com/in/satyanadella/",
    "https://www.linkedin.com/in/williamhgates/"
  ],
  "concurrency": 10
}

---

📤 Output Format & Schema

Each processed prospect is stored in the default dataset. All your original spreadsheet columns are retained alongside these verified fields:

{
  "firstName": "Satya",
  "lastName": "Nadella",
  "domain": "microsoft.com",
  "linkedinUrl": "https://www.linkedin.com/in/satyanadella/",
  "status": "found",
  "email": "satya.nadella@microsoft.com",
  "confidence": "high",
  "is_catch_all": false,
  "smtp_response": "250 OK — Mailbox exists",
  "error_message": "",
  
  "phone": "+1-425-882-8080",
  "job_title": "Chief Executive Officer",
  "company_name": "Microsoft Corporation",
  "custom_crm_id": "LEAD-98214"
}

Output Field Reference

• email: The verified deliverable corporate email address.
• status: found (verified mailbox exists) or not_found (mailbox does not exist).
• confidence: high (verified non-catch-all inbox) or medium (verified inbox on catch-all domain).
• is_catch_all: true if the company mail server accepts all addresses for this domain.
• smtp_response: Exact response from the mail exchanger (e.g. 250 OK — Mailbox exists).
• error_message: Informational detail if a prospect was skipped or invalid.

❓ Frequently Asked Questions (FAQ)

What happens if an email cannot be found?

If you supply Names and Company Domains (Option A), you are only charged when an email is successfully found and verified. Unfound emails cost $0.00.

Why does LinkedIn URL enrichment cost $10 per 1,000 processed?

LinkedIn does not provide public email APIs and aggressively blocks automated requests. Enriching a LinkedIn profile URL requires dedicated headless browsers and premium residential proxy routing to extract the person's name and company domain before running email permutations. This completely protects your personal account from bans, but incurs third-party cloud infrastructure costs ($0.01 per profile).

How can I get the $5 / 1,000 pricing?

Provide your prospects' First Name, Last Name, and Company Website / Domain. If your lead source (e.g. Apollo, Google Maps, CRM export) already contains their website, pass that spreadsheet directly! You bypass the LinkedIn scraping step completely and pay only $5 per 1,000 verified emails found.

How is this different from Apollo or Hunter?

Apollo and Hunter charge substantial monthly recurring subscriptions ($49–$149/mo) and often rely on historical databases that haven't been re-verified in months, causing cold email bounces. Our Actor conducts live, real-time SMTP handshakes directly with the destination mail server to confirm deliverability before charging you.

What is Catch-All detection?

Some corporate email servers (especially Microsoft 365 configurations) are set to "Accept All" (Catch-All), meaning the server responds 250 OK to any email address tested. When we detect a Catch-All server, we mark the result with is_catch_all: true and set confidence to medium so you can choose whether to mail them based on your campaign risk tolerance.

Does this guarantee low bounce rates?

Yes. By verifying real mail exchanger handshakes and filtering disposable domains, syntax errors, and invalid mailboxes, your bounce rate on high confidence emails stays well below the 2% threshold required for cold email inbox deliverability.
