Email finder extensions turn your browser into a prospecting machine by pulling verified contact data directly from LinkedIn profiles and company websites without switching tabs or tools.
This guide breaks down the top email finder extensions for B2B sales teams and shows you what features actually matter for hitting your numbers.
What Makes the Best Email Finder Extension?
An email finder extension pulls verified contact data directly from LinkedIn profiles and company websites while you browse, eliminating the need to switch between tabs or tools. Sales reps typically waste hours jumping between LinkedIn, Google, and their CRM to piece together contact information. The right extension overlays this data in your browser and syncs it to your CRM automatically.
The best extensions do more than find emails. They verify deliverability in real-time, sync contacts directly to your CRM, and handle bulk exports from LinkedIn Sales Navigator searches. Data accuracy separates tools that help you hit quota from tools that waste your time with bounced emails.
Core capabilities that matter:
In-browser contact discovery: Pull email addresses and phone numbers without leaving LinkedIn profiles or company websites
Email verification: Real-time checks confirm addresses are active before you add them to outreach lists
Bulk export: Extract multiple contacts from Sales Navigator searches instead of clicking through profiles one by one
CRM synchronization: Automatic data flow to Salesforce, HubSpot, and sales engagement platforms without manual entry

Best Email Finder Extensions for B2B Sales
These extensions are built for sales teams that need accurate contact data to hit their numbers. Each tool approaches the problem differently, but they all solve the core issue: turning LinkedIn profiles into actionable prospect lists.
1. ZoomInfo
The ZoomInfo browser extension gives you access to the most comprehensive B2B database available. This isn't just about finding email addresses. You get direct-dial phone numbers, detailed company information, and real-time buying signals all from a single browser extension.
The extension connects to ZoomInfo's platform, which processes over 1 billion buying signals monthly across 100 million company profiles and 500 million contact profiles.
When you're viewing a LinkedIn profile, you see not just contact information but also org charts, technology stack details, and intent data that tells you if the company is actively researching solutions like yours. The extension syncs directly with Salesforce, HubSpot, Outreach, and Salesloft. CoPilot surfaces insights and automates workflows inside GTM Workspace, so you spend less time on research and more time selling.
This level of data depth changes how you approach prospects. Instead of sending generic outreach, you can reference specific technologies they use, recent company news, or buying signals that indicate they're in-market for your solution. ZoomInfo maintains GDPR and CCPA compliance with built-in data management tools.
The extension works best for mid-market and enterprise sales teams, account-based marketing programs, and revenue operations teams that need data they can trust.
Key Features:
Verified contact data with both email addresses and direct-dial phone numbers backed by real-time verification
Company intelligence including technology stack, employee count, recent news, and org chart information
Buying signals with intent data that shows when companies are researching relevant solutions
Native CRM sync with automatic data flow to Salesforce, HubSpot, Outreach, and Salesloft
Compliance tools for GDPR and CCPA compliant data collection and management
GTM Workspace integration with CoPilot for AI-powered insights and workflow automation
Bulk export capabilities from LinkedIn Sales Navigator searches
2. Hunter
Hunter built its reputation on domain search functionality. The extension finds all email addresses associated with a specific company domain, making it useful when you know the target company but not the specific contact. When you enter a company domain, Hunter shows you the email format the company uses and provides a list of verified addresses.
The tool focuses on simplicity and pattern recognition. Author Finder locates contact information for content creators and thought leaders. The verification API confirms email deliverability before you add contacts to your outreach list. Bulk tasks let you process multiple domains or names at once instead of running individual searches.
Hunter provides confidence scores for each email address based on the number of sources confirming the contact. Export options include CSV downloads and direct integrations with CRM platforms. The approach works well for broad prospecting campaigns where you need multiple contacts from the same organization.
Key Features:
Domain search that identifies all email addresses associated with a company
Email pattern recognition that shows company email formats
Author Finder for locating content creators and thought leaders
Verification API with confidence scores based on multiple data sources
Bulk task processing for multiple domains or contact names

3. Snov
Snov combines email finding with automated outreach tools.

You can build lists from LinkedIn, verify the contacts, and launch automated email campaigns without switching tools.
The platform includes LinkedIn integration for profile extraction and prospect list building. The email verifier confirms deliverability before you launch campaigns. Drip campaign functionality lets you set up multi-touch sequences that trigger based on recipient behavior. The credit-based system covers both finding and verifying contacts.
The tool works well for teams that want both prospecting and engagement in one platform. The data accuracy varies significantly depending on the industry and geography. The platform works better for high-volume, lower-touch outreach campaigns rather than targeted account-based approaches.
Key Features:
Email finder with LinkedIn profile extraction
Drip campaign automation for multi-touch email sequences
Email verifier that confirms deliverability before sending
LinkedIn integration for prospect list building
Credit-based system covering both finding and verification
Campaign triggers based on recipient behavior

4. Lusha
Lusha focuses on speed and simplicity. The extension provides one-click access to contact information directly from LinkedIn profiles, making it popular among individual sales reps and recruiters who need quick lookups. The interface is clean and the process is fast, but the data coverage is limited compared to more comprehensive platforms.
The tool operates on a credit system where revealing an email address costs 1 credit, while revealing a phone number costs 10 credits. Contact information appears directly on LinkedIn profiles without requiring you to navigate to a separate platform. The extension captures both personal and professional email addresses when available.
Lusha works best for users who need occasional contact lookups rather than systematic prospecting campaigns. Integration options include Salesforce, HubSpot, and other CRM platforms for syncing discovered contacts. The lack of advanced features like buying signals or detailed company information limits its usefulness for complex B2B sales processes.
Key Features:
One-click contact reveal directly from LinkedIn profiles
Credit-based pricing with separate costs for emails and phone numbers
Personal and professional email address coverage
Direct dial phone numbers for key contacts
CRM integration with Salesforce, HubSpot, and other platforms

Sales Navigator users can export entire search result pages instead of clicking through individual profiles.
Bulk search capabilities let you process multiple LinkedIn profiles at once. Lead list building tools organize contacts by company, role, or custom tags. Search filters help you narrow results by location, industry, company size, and job function before extraction. The extension captures email addresses, phone numbers, and LinkedIn profile URLs in a single click.
Export options include CSV downloads and direct CRM integrations. Team collaboration features let multiple users share prospect lists and coordinate outreach efforts. The platform includes email verification to confirm deliverability before you add contacts to campaigns.

The extension extracts contact information from LinkedIn profiles with a single click. Recruiting use cases benefit from the personal email coverage and direct dial phone numbers. The platform captures job history, education, and skills data alongside contact information for fuller candidate profiles.

Search filter capabilities let you narrow prospects by funding stage, investor involvement, technology stack, and other startup-specific criteria. The verification process confirms email deliverability before adding contacts to your lists.

How to Choose an Email Finder Extension
The best email finder extensions solve two problems: they find accurate contact information and they fit into your existing workflow without creating more work. Too many tools focus only on finding emails without considering data quality or process integration. Your choice should match your team's specific needs, whether that's speed and simplicity for individual contributors or data accuracy and compliance features for enterprise teams.
Evaluate extensions across four key dimensions:
Data accuracy and verification: Real-time validation and bounce rate tracking
Chrome extension and LinkedIn functionality: In-browser capture and Sales Navigator compatibility
CRM integration and data export: Automatic sync to your existing tech stack
Pricing and credit systems: Cost per contact and team scalability
Data Accuracy and Verification
Bounced emails hurt your sender reputation and waste time you could spend selling. Look for extensions that verify email addresses in real-time and provide transparency about their data sources and collection methods. Verification quality separates tools that help you hit quota from tools that damage your deliverability.
Key considerations:
Real-time verification that confirms email addresses are active before you add them to outreach lists
Confidence scores or verification status for each contact showing data source quality
Bounce rate tracking to measure actual deliverability of discovered contacts
Data transparency about collection methods and source freshness
Chrome Extension and LinkedIn Functionality
The extension should work where you already spend time prospecting. LinkedIn profile support and Sales Navigator compatibility matter most for B2B sales teams. In-browser experience quality determines whether the tool speeds up your workflow or adds friction.
Key considerations:
LinkedIn profile extraction that captures contacts without leaving the page
Sales Navigator compatibility for bulk exports from search results
One-click capture vs. multi-step processes that slow you down
Bulk export capabilities for processing multiple contacts at once
CRM Integration and Data Export
If you're stuck doing manual data entry, the tool isn't working. The extension should sync found contacts directly to your CRM and sales engagement platforms without additional steps. Workflow integration matters just as much as data quality.
Key considerations:
Native integrations with Salesforce, HubSpot, and your preferred CRM
Field mapping that puts contact data in the right CRM fields automatically
CSV export for bulk uploads when direct integration isn't available
API access for custom workflow automation and data synchronization
Pricing and Credit Systems
Most extensions use credit-based pricing where each contact reveal consumes credits. Understanding the pricing model helps you calculate cost per contact and compare tools accurately. Team vs. individual pricing can significantly impact total cost of ownership.
Key considerations:
Credit costs for email vs. phone number reveals
Monthly subscription limits and overage charges
Team pricing that scales with user count
Free tier limitations and what's included in trial periods
Free Email Finder Extensions
Most email finder extensions offer free tiers or trials so you can evaluate before committing to paid plans. Free options work well for occasional lookups or testing data quality before rolling out to your team. Understanding what's included in free tiers helps you determine if a tool meets your needs without paying upfront.
Free tier options typically include:
ZoomInfo Lite provides Chrome-based prospecting with monthly credits for contact reveals
Hunter offers 50 credits per month for domain lookups and email verification
Snov includes 50 free credits monthly for email finding and verification
Lusha provides up to 70 credits per month for contact reveals
GetProspect offers 50 free credits monthly for LinkedIn email extraction
Free tiers let you test data accuracy and workflow fit before scaling to paid plans. Monthly credit limits reset each billing cycle, so you can continue using free tiers indefinitely for low-volume prospecting. Most platforms require credit card information even for free trials, so check cancellation policies before signing up.
Frequently Asked Questions
Which email finder extension works best with LinkedIn Sales Navigator?
ZoomInfo's extension provides the deepest Sales Navigator integration, pairing search results with verified contact data, company intelligence, and bulk processing capabilities that most competitors lack.
Can email finder extensions get my LinkedIn account banned?
Good extensions use rate limiting to stay within LinkedIn's guidelines. Aggressive scraping tools don't, and they can get your account restricted.
Do email finder extensions work on company websites besides LinkedIn?
Yes, most extensions work on any website where they can identify names and company information. They're particularly effective on company team pages, conference speaker lists, and industry directories.
How accurate are the email addresses found by these extensions?
Accuracy varies by provider. ZoomInfo delivers high accuracy rates because of its comprehensive verification process, while other tools often return less reliable data.
Can I use multiple email finder extensions at the same time?
You can install multiple extensions, but this often creates confusion and duplicate data. Choose one primary tool that meets your needs rather than trying to combine multiple solutions.
Choosing Your Email Finder Extension
The right email finder extension becomes invisible in your workflow. You find better prospects faster, send more personalized outreach, and spend less time on manual research. Match the tool to your workflow rather than forcing your process to fit the tool's limitations.
Key decision factors:
Data accuracy and verification quality that protects your sender reputation
Workflow integration with your existing CRM and sales engagement platforms
Team size and whether you need individual or enterprise-grade features
Prospecting volume and whether credit limits match your monthly needs
ZoomInfo goes beyond point lookups to deliver contact intelligence, company data, and buying signals that change how you approach prospects. The extension connects to GTM Workspace where CoPilot automates research and surfaces insights that help you personalize outreach at scale. For teams that need more than email addresses, ZoomInfo provides the data foundation for comprehensive GTM execution.
