Hunter Automation - A Natural-Language-Driven Email Intelligence Tool for Hunter.io

Overview of Skills

Hunter Automation lets you use natural-language commands to call Hunter.io’s email intelligence capabilities—search domain email addresses, find emails for specific contacts, verify deliverability, manage leads, and monitor API usage limits.

Use Cases

1. B2B Sales Lead Prospecting

Sales teams can quickly obtain bulk email addresses for target companies, filter executives and decision-makers by department and title, and support international outreach, business development, and customer outreach scenarios.

2. Email Deliverability Verification

Before sending marketing or cold-start emails, bulk-verify whether email addresses are valid and deliverable to reduce bounce rates, protect the sending domain’s reputation, and improve email marketing ROI.

3. Finding Investor/Partner Contact Emails

Founders and BD teams can quickly find publicly available email addresses for target investors and partners using a company name or domain—useful for fundraising pitches and business collaboration communication.

Core Features

1. Domain Email Search

Search all publicly available email addresses by domain or company name. Supports filtering by department (Sales, IT, Finance, etc.), seniority level (junior, senior, executive), and email type (personal/work or general).

2. Find Emails for Specific People

Infer the most likely email address based on a name and company/domain. Supports both single and bulk queries, with configurable request duration to balance accuracy and speed.

3. Email Deliverability Verification

Check whether an email address is valid, inspect MX record configuration, and evaluate delivery risk. Returns verification status and a deliverability score to help identify invalid emails and catch-all domains.

4. Email Count Estimation

Estimate the total number of emails Hunter has indexed for a domain, including breakdowns by type, department, and seniority level—useful for assessing a target company’s email richness without consuming API quotas.

5. Lead Management

Create or update lead records using email addresses, automatically deduplicate, and store metadata such as name, title, and company for easier follow-up later.

6. Account Quota Monitoring

View, in real time, your remaining Hunter API search counts, verification quota, and account plan details—helping you avoid exceeding limits during bulk operations.

FAQs

What is Hunter Automation?

Hunter Automation is a skill that integrates the Hunter.io API via Composio MCP, enabling you to use natural-language commands to perform Hunter’s email search, verification, and management functions without writing code.

What are the limits of the Hunter.io free plan?

On the free and basic plans, a domain search returns up to 10 results per request; paid plans can return more. The email count estimation feature does not consume quota, while search and verification will deduct the corresponding allocations based on your account plan.

How do I integrate it into my workflow?

Add the Composio server (https://rube.app/mcp) to an MCP-supported client, connect your Hunter.io account to complete API authentication, and then directly call the various functions using natural-language commands.
