How to Extract Emails, Phones and WhatsApp From a Website for Free

Contact Finder by LeadTrapper is a free Chrome extension that extracts the contact details a business publishes on its own website: email addresses, phone numbers, WhatsApp numbers, addresses and social media profiles. Open the site, click the icon, and it lists what it found, checking the site’s Contact, Team and Branches pages for you. Since version 1.1.0 it can also scan a whole list of websites, or all your open tabs, in one go. You can then download everything to Excel or CSV.

What Contact Finder Extracts

When you click the icon on a business website, Contact Finder reads that site and a few of its own pages where contact details usually sit, such as Contact, Team, About and Branches. It then lists five kinds of contact:

• Emails, including addresses a site hides from simple copy-paste.
• Phone numbers, in international format, with the country worked out from the website.
• WhatsApp numbers, taken from chat buttons and WhatsApp links.
• Addresses of offices and branches, each with a map link.
• Social media profiles, with their handles.

When a site publishes no email, the page with its contact form is saved instead, so you still have a way to reach the business. Each website is also tagged with the system it is built on when Contact Finder can tell, such as Shopify, WooCommerce, Wix, Squarespace or WordPress.

It also leaves out what is not a contact: no-reply addresses, image file names, dates, fax numbers and share buttons.

How to Use It

Install Contact Finder from the Chrome Web Store and pin it to the toolbar: click the puzzle icon at the top right of Chrome, then the pin next to Contact Finder.

1. Open the website of a business, for example a clinic, a restaurant or a supplier.
2. Click the Contact Finder icon. It shows how many pages of the site it checked and lists the contacts by type.
3. Tick the contacts you want and press Add to my list.
4. Open the next website and click the icon again. Your list keeps growing.
5. Press Download my list and choose Excel or CSV.

Scan a List of Websites in Bulk

Version 1.1.0, released on 21 October 2026, added a full-page list where you can scan many websites at once. Open it from the popup with Open full list · scan many websites.

1. Paste the websites, one per line or separated by spaces or commas.
2. Press Scan these websites. The first time, Chrome asks your permission to read the websites; choose Allow.
3. Contact Finder opens each website and its Contact, Team, About and Branches pages, one after another, and adds every contact to your list. It shows live progress, and Stop ends the scan at any time.

Or press Scan my open tabs to read every website open in your browser. This helps with sites that show their contacts only after they load in a tab, or that ask you to prove you are human.

There is no limit on the number of websites, contacts or downloads. Websites are read one at a time with a pause between them, 2 seconds by default and adjustable up to 60, so a long list takes a while. Search engines, social networks and review sites in your list are skipped, and a website that cannot be opened is listed with the reason.

What We Found in a Real Test

On 13 October 2026 we ran Contact Finder on the websites of five dental and aesthetic clinics in Dubai, chosen from a Google Maps search. We clicked the icon once on each home page and recorded what it listed. We are not naming the clinics or repeating their details here.

Four of the five sites returned contact details, 31 in all. Clinic 1 lists two branches, and Contact Finder gave each phone number and address the name of its branch. Social profiles were the most common find and emails the rarest. That matches our Google Maps scans, where only 15% to 47% of businesses had an email on their website.

Clinic 5 returned nothing: Contact Finder checked one page and found no contact details in it. In that case the popup suggests opening the site’s Contact page and trying again, which is the right next step. This was five websites in one city on one day, so it shows what to expect, not a success rate.

Who Each Contact Belongs To

Business websites often list several addresses: a general inbox, a booking desk, team members and branches. Contact Finder labels each contact as a general inbox, a department, a person (with their name when the page shows it) or a branch (with the branch name), and shows which page it came from. Phone numbers and social profiles are labelled too: the company’s own, or a team member’s, with their name.

The label comes from the nearest heading or name on the page, so it is only as tidy as the website. In our test a few labels were the day of the week the clinic printed next to its number. Read the label as a hint about where the contact sits, and check the page when it matters.

Check Emails Before You Write

On the full list page, Check emails does two things:

• It flags typing mistakes in common email providers, such as gmial.com, and suggests the likely address, and it flags temporary throwaway inboxes.
• It asks a public DNS service, Cloudflare’s 1.1.1.1, whether each email’s domain can receive mail at all. Only the domain name, such as acme.com, is sent, never the address.

You can then filter the list for emails that work or emails that will bounce. The check cannot prove that one person’s inbox exists; no tool running in a browser can. It catches the addresses that cannot work, before you write to them.

Organise and Follow Up

The full list page turns the contacts into a simple follow-up list:

• Search and filters by type (emails, phones and WhatsApp, addresses, social media, contact forms), by status and by email check.
• A status for each contact: New, Contacted, Replied, Not interested or Customer.
• The website platform, useful if you sell to businesses on one system, such as Shopify or WordPress stores.
• A WhatsApp first message, optional. Write it once with {{name}}, {{business}} or {{website}}, and it is added to every WhatsApp chat link with the details filled in. You still read it and press Send yourself in WhatsApp.

Export to Excel or CSV

Download my list saves every contact you added, from every website, in one file. You choose:

• Excel, which opens directly with each contact on its own row.
• CSV, for importing into a CRM or a spreadsheet tool.
• Phone numbers only (send-ready), a clean list of numbers for messaging.
• Phone contacts (.vcf), to import into your phone or Google Contacts, from the full list page.
• Copy for Google Sheets, which copies the table so you can paste it into a spreadsheet.

On the full list page, downloads include the rows your filters show, so you can export only the emails that work, for example. The list stays in your browser until you press Clear, so you can collect over several sessions.

What It Does Not Do

• It works on business websites only. It refuses search engines and social networks, such as Google, Google Maps, LinkedIn, Facebook, Instagram, TikTok and X.
• It reads websites only when you ask. Clicking the icon reads the site you are on, and a list or your open tabs is read only when you press Scan. Nothing runs in the background.
• It reads what the website publishes. If a site shows no email, there is no email to find, and it does not guess addresses.
• It runs in Chrome on a computer. Browser extensions cannot be installed on a phone.

Free Extension, Cloud Scraper or Desktop App?

Searches for a contact details scraper mostly turn up cloud services that crawl a list of websites for you and charge by usage, which suits developers and large one-off jobs. Contact Finder covers both everyday cases for free: checking businesses as you research them, and reading a list of websites you already have. The LeadTrapper Windows app adds finding the businesses and messaging them.

The app’s Email Finder, called Website Contact Finder under Google Maps in its left menu, uses the same rules as the extension. Give it your own list of websites, or a business type and a city, and it reads each site’s home page and its contact, team and branch pages. Our guide on how to find business email addresses covers the labels and the email check in detail.

Getting Contact Numbers for Marketing

Finding a number is the first step. Before you message anyone, two things decide whether it works. First, check which numbers are actually on WhatsApp, so you do not waste messages; the WhatsApp Number Filter guide shows how. Second, keep to WhatsApp’s rules on unsolicited messages, which the cold outreach policy guide explains.

If your leads come from Google Maps rather than websites, the free Maps Lead Extractor reads a results page, and the Google Maps scraper in the Windows app collects whole areas with phone numbers and websites. Use the contacts you collect lawfully and follow the anti-spam and privacy rules of the places you contact.
