Findymail MCP with Claude: Verified Lead Enrichment for Sales Teams
The short answer
Claude works with Findymail through the Model Context Protocol, an open standard that lets Claude securely use the tool. Once connected with an API key, Claude can search for verified B2B email and phone contacts, check email validity, enrich CRM records and prepare exports, all from plain-English instructions. Your team approves any outreach before it is sent.
What is Findymail?
Findymail is a B2B data provider offering verified email addresses and phone contacts for sales prospecting. Sales development teams, account managers, recruiters and marketing operations people typically use it to build target lists, check that contact details are current and keep customer records complete. It is often used alongside a CRM, where it can help fill gaps in existing records.
How Claude connects to Findymail through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool. Findymail offers an MCP server and a direct API, so Claude can reach its contact data without your team copying files back and forth.
Once connected, Claude can typically look up verified prospects by company, role or location, verify whether an address is deliverable, enrich existing CRM records with missing details and prepare exports for your team. You describe what you need in ordinary language, and Claude carries out the steps.
Access is controlled by the API key you provide, and you decide what that key can do. Consequential actions, such as sending outreach emails or overwriting CRM fields, can be set to require a person's approval first. Every action is logged so your operations team can review what happened.
What you can automate
Building targeted prospect lists
A sales development representative describes the ideal buyer, for example operations directors at mid-sized logistics firms in the UK. Claude searches Findymail for matching contacts, removes duplicates and returns a clean, verified list ready for outreach. The representative reviews the list before anything is used, saving hours of manual searching.
Verifying email addresses before campaigns
Before a campaign goes out, a marketing operations manager asks Claude to check a list of addresses. Claude uses Findymail's verification to flag invalid or risky addresses, so the team can remove them. This typically protects sender reputation and reduces bounced emails.
Enriching CRM records
A customer success lead has many accounts with missing phone numbers or job titles. Claude identifies incomplete records in the CRM, looks up the missing details in Findymail and proposes updates for review. Approved changes are written back, leaving the CRM tidier and more useful for account teams.
Automating scheduled exports
A revenue operations analyst needs a weekly export of new contacts in a target region. Claude prepares the export with the agreed fields and format, and the analyst receives it in the usual place. Requests are made in natural language, so no technical knowledge is needed each week.
Preparing personalised outreach
An account executive wants to contact new prospects with relevant context. Claude gathers verified contact details and drafts personalised emails based on the prospect's role and company. The executive edits and approves each message, and nothing is sent without that sign-off.

Frequently asked questions
What does the Findymail MCP server do?
The Findymail MCP server lets Claude access Findymail's contact data through a standard connection. Claude can then search for verified B2B contacts, check email validity, enrich records and prepare exports when asked in plain English. It acts as a secure bridge, so your team does not need to switch between tools or handle raw data manually.
Is connecting Findymail to Claude secure?
Security depends on how the connection is set up. We use the API key sign-in method with least-privilege permissions, require approval for consequential actions and keep audit logs of activity. Credentials can be rotated or revoked at any time, so you stay in control of what Claude can access.
What can Claude actually do with Findymail?
Typically, Claude can search for prospects by criteria you specify, verify email addresses, enrich CRM records with missing details, prepare exports and draft outreach. Sending emails or changing records can be set to require a person's approval first, so nothing consequential happens unchecked.
How long does setup take?
Timelines vary with the number of workflows and the systems involved. A focused setup covering one or two workflows often takes a few weeks, including the free audit, testing and team training. We confirm the timeline during the audit, once we understand your current process.
Which plan or permissions do I need?
You need a Findymail account with an API key, and the key's permissions should match the actions you want Claude to take. Your plan and data allowances are set by Findymail, so we recommend checking your current arrangement. During the audit we identify the minimum permissions required for your workflows.
