Finding C-suite emails at scale normally takes hours. You jump between tools, export and import files, and manually verify each contact. This guide shows a different approach.
By connecting Scalelist to Claude using the Model Context Protocol (MCP), you can research target companies, identify executives, and enrich their emails in one conversation. The demonstration in this video found 55 valid emails from 131 C-suite contacts across 63 companies in 5 minutes. Total cost: 55 credits.
What Is an AI Email Finder?
An AI email finder uses artificial intelligence to search for, enrich, and verify business email addresses at scale. It combines AI’s ability to understand instructions and research companies with a verified email database that can confirm whether an address is deliverable.
Claude is the AI. Scalelist is the email verification database. The Model Context Protocol (MCP) connects the two.
With this setup, you describe what you need in plain English. Claude handles the research, extraction, and enrichment automatically. You do not write code. You do not switch between platforms.
What You Need to Get Started
You need two things:
- A Claude account. A free account allows one custom connector. If you already use other connectors, you will need Claude Pro at $20 per month to add Scalelist.
- A Scalelist account. Sign up at scalelist.com. New accounts receive free credits. These were enough to cover the entire demonstration in this video.
That is it. No developer tools. No command line.
How to Connect Scalelist to Claude
The setup takes under 4 minutes. Here are the four steps.
Step 1: Create a Scalelist API Key
Log into your Scalelist account. Click API in the left navigation panel. Click the blue New Key button. Copy the key that appears.
The API key is a secure connector between your Scalelist account and Claude. Keep it private.
Step 2: Add Scalelist as a Custom Connector in Claude
Open Claude. Click Customize in the left panel. Select Connectors. Click Add Custom Connector.
Name it Scalelist. Paste the MCP URL from the Scalelist documentation. Paste your API key. Click Add.
Step 3: Set Permissions to Always Allow
After adding the connector, a dropdown shows “Needs Approval.” Click it and select Always Allow. This lets Claude call Scalelist tools without asking for permission each time.
Step 4: Verify the Connection
Ask Claude: “Are you connected to my Scalelist MCP?” Claude lists the available Scalelist functions. You are ready.
How to Find C-Suite Emails Step by Step
The workflow from the video has four stages. Each stage uses one Claude prompt.
Stage 1: Research Target Companies
Ask Claude to build a list of companies in your target market. The example from the video used finance companies in Miami. Claude uses its training data to return a categorized list of companies with names and websites.
No Scalelist credits are used yet. This stage is free.
Stage 2: Extract C-Suite Contacts
Ask Claude to identify the C-suite executives at those companies. Specify the roles you want: CEO, CFO, CRO, CMO, COO.
Claude builds a spreadsheet with first name, last name, job title, and company. Still no credits used.
Stage 3: Enrich Emails Using Scalelist
Now ask Claude to find verified emails for each contact using your Scalelist MCP. Claude calls Scalelist for each contact, collects the email status, and adds two columns to your spreadsheet: Email and Email Status.
Each found email costs one credit. Each not-found result costs nothing.
Stage 4: Export
Ask Claude to export the results. Options include CSV download or push to Google Drive. The spreadsheet contains every contact with their email and verification status.
What the Email Statuses Mean
Every email Scalelist finds goes through real-time verification. You see one of three results.
Valid means the email passed verification. The mail server confirmed the inbox exists and accepts messages. These emails are ready for outreach.
Risky means an email was found but could not be confirmed. This usually happens with catch-all mail servers. The email may still deliver. You decide whether to include it in your campaigns.
Not Found means Scalelist found no email for that contact. You are not charged for these results.
Results from the video
131 C-suite executives researched across 63 companies:
- 55 valid emails found
- 20 risky emails
- 56 not found
Total cost: 55 credits. The free tier covered the entire demonstration.
Frequently Asked Questions
Do I need coding skills to set this up?
No. The setup takes under 4 minutes and requires only copying and pasting an API key. No code, no command line, no technical background needed.
What is MCP?
MCP stands for Model Context Protocol. It is a standard that allows AI assistants like Claude to connect to external tools and take actions on your behalf. When you connect Scalelist’s MCP to Claude, Claude can call Scalelist’s email verification API directly from the chat.
What is the difference between valid and risky emails?
A valid email passed real-time SMTP verification. The mail server confirmed the inbox exists. A risky email was found but could not be confirmed due to a catch-all mail server configuration. Risky emails may still deliver. Valid emails are the safer choice for high-volume cold email campaigns.
How many credits does this workflow use?
One credit per valid or risky email found. Not found results cost nothing. In the video demonstration, 131 contacts were enriched for 55 credits total.
Can I use Claude’s free account?
A free Claude account allows one custom MCP connector. If Scalelist is your first connector, the free tier works. If you already use other connectors, you need Claude Pro at $20 per month to add a second one.
Conclusion
An AI email finder that combines Claude and Scalelist gives you a complete prospecting workflow inside a single chat. You research companies, identify executives, and enrich emails without switching tools or writing code.
55 valid emails from 131 C-suite contacts. 5 minutes. 55 credits. All within the free tier.
