ContactHarvest-Email-Extractor by Tanay Roy

ContactHarvest — Email & Phone Extractor helps you find email addresses and phone numbers from web pages quickly, cleanly, and privately.

Whether you are reviewing contact pages, researching businesses, checking directories, collecting public contact information, or building outreach lists, ContactHarvest scans the page you are viewing and organizes discovered emails and phone numbers into a simple, export-ready list.

Extract emails and phone numbers from web pages

Open a web page, click the ContactHarvest icon, and instantly view the contacts found on that page. ContactHarvest detects email addresses and phone numbers from visible page text, contact links, structured data, page attributes, and common obfuscated formats.

Phone numbers can be displayed in normalized international format when available, making them easier to copy, review, and export.

Built for cleaner contact extraction

ContactHarvest is more than a basic email extractor. It helps you understand the quality of each result with confidence indicators:

High confidence contacts are usually found in strong sources such as mailto links, tel links, schema markup, or multiple reliable signals.

Medium confidence contacts are validated or found in structured contexts.

Low confidence contacts are still shown, but marked for review when they come from weaker page-text matches or suspicious number patterns.

This helps you separate useful contact data from noisy results.

Highlight, copy, and export contacts

ContactHarvest gives you practical tools for working with discovered contacts:

View emails, phone numbers, and matched email-phone pairs
Highlight found contacts directly on the page
Copy emails or phone numbers to your clipboard
Export contacts as CSV, XLSX, JSON, or TXT
Copy paired email and phone results
Re-scan dynamic pages when contacts load after the page opens
Advanced workflows for larger contact research

For larger research tasks, ContactHarvest supports premium workflows:

Capture mode — browse normally while ContactHarvest accumulates contacts across multiple pages
Sessions — save and revisit completed capture sessions
Crawl — scan pages from a website automatically with depth, page limit, delay, and safe-mode controls
Bulk extraction — process a list of URLs and export combined results

These tools are useful for reviewing business directories, contact pages, customer lists, event directories, and research targets across multiple pages.

Filtering and customization

ContactHarvest includes settings to control what gets extracted and displayed:

Extract emails, phone numbers, or both
Filter by confidence level
Filter role-based emails such as info@, sales@, support@, and noreply@
Choose phone display format
Show or hide the toolbar contact count
Enable auto-highlight when opening the popup
Choose light, dark, or auto theme

Premium users can also use site blacklists, email allow/block filters, email pattern filters, and phone country filters to reduce noise and focus on the contacts that matter most.

Local-first privacy

ContactHarvest is built with privacy in mind. Extracted emails, phone numbers, page URLs, and page content stay in your browser. Contacts are stored locally in browser storage.

The add-on contacts NameToProfile only to validate your API key and refresh your credit balance. Extracted contact data is not uploaded to NameToProfile. Credits are never deducted by the extension; the credit balance is only used to determine access tier.
