Hunter.io offers a tiered pricing structure designed to accommodate different user needs and budgets. The platform provides both monthly and yearly subscription options, with significant discounts available for annual commitments.

Current Pricing Tiers

As of May 2025, Hunter.io structures its pricing in the following tiers:

• Free Plan: Limited functionality with 50 searches per month
• Starter Plan: $34/month (monthly billing) or approximately $24/month (annual billing)
• Growth Plan: $104/month (monthly billing) or approximately $73/month (annual billing)

Credit-Based System

Hunter.io operates on a credit-based system for its core functionalities:

• Search Credits: Used when looking up email addresses associated with a domain
• Verification Credits: Consumed when verifying the deliverability of email addresses

Each plan tier offers a specific allocation of these credits, which reset monthly. Users can perform actions until they exhaust their monthly credit allowance.

Value Analysis for Different Users

Individual professionals like freelance writers or solo consultants often find the Free or Starter plans sufficient. The key question is how many prospects you need monthly—50 free searches work for limited outreach, while the Starter plan's 500 monthly credits suit more active networkers.

Small agencies managing multiple client campaigns typically benefit most from the Growth plan, as it provides enough capacity to handle several small to medium client accounts while enabling team collaboration.

Large sales organizations with high-volume prospecting needs typically require the Business plan or custom enterprise solutions. These teams value the higher credit limits, team management capabilities, and advanced integrations with enterprise CRM systems.

Domain Search Feature

The Domain Search feature is a cornerstone of Hunter.io's functionality. It allows users to discover email addresses associated with a specific company domain. This capability is invaluable for B2B marketers and sales professionals looking to connect with decision-makers at target organizations. By simply entering a company's domain, you can access a list of email addresses, complete with verification status and confidence scores. This feature significantly reduces the time spent on manual research and increases the accuracy of your outreach efforts.

Email Finder Tool

When you have the name of a specific prospect but lack their email address, the Email Finder tool comes to the rescue. This feature enables you to find professional email addresses by inputting a person's name and their company domain. Hunter.io utilizes its extensive database and pattern recognition algorithms to identify the most likely email address format used by the organization. This tool is particularly useful for personalized outreach and when targeting specific individuals within a company.

Email Verification System

Hunter.io's Email Verification system is widely regarded as one of the most accurate in the market. The verification process involves multiple steps:

1. Syntax Checking: Ensures the email follows proper formatting.
2. Domain Validation: Confirms the domain exists and can receive emails.
3. Mail Server Verification: Checks if the email address is registered on the domain's mail server.

This multi-step verification process helps you maintain clean email lists, reducing bounce rates and protecting your sender reputation. For marketing and sales teams, this means higher deliverability rates and more effective email campaigns.

Bulk Verification Capabilities

For larger campaigns, Hunter.io offers Bulk Verification capabilities that allow you to validate multiple email addresses simultaneously. This feature is a game-changer for marketing teams working with extensive contact lists or sales professionals preparing large-scale outreach campaigns. By streamlining the verification process, you can save considerable time while ensuring high deliverability rates across your entire contact database.

Hunter.io places a strong emphasis on data security and regulatory compliance, implementing a multi-layered approach to protect user information and maintain trust. The platform employs several key security measures to safeguard sensitive data and ensure adherence to industry standards.

Database Security and Encryption

Hunter.io restricts database access to approved IP addresses within their internal Google Cloud or Tailscale network, significantly reducing exposure to external threats. Sensitive data, such as email verifications, are pseudonymized to mitigate the risk of exploitation in the event of a breach.

For data encryption, Hunter.io uses robust algorithms:

• Password reset, email change, and validation links are also encrypted with aes-256-cbc

Access Controls and Monitoring

The platform implements strict access control through a role-based access control (RBAC) model, ensuring staff only have access to data necessary for their roles. This adheres to the principle of least privilege, a cornerstone of modern cybersecurity practices. Additional access control measures include:

• Immediate revocation of employee access to customer data upon termination
• Mandatory multi-factor authentication (MFA) for accessing the production environment
• Logging of all high-risk actions and changes in the production environment
• Automated systems for detecting deviations or malicious usage patterns

Regulatory Compliance

Hunter.io is committed to major data protection regulations, particularly the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA). The company's practices include:

• Ensuring transparent data usage

Regular security audits and vulnerability assessments are conducted to proactively identify and address risks, keeping the platform aligned with evolving security standards.
