Find the work email of anyone on LinkedIn in one click. Domain from official registers, mailbox verified. Free, 100 lookups a day. Find the work email behind any LinkedIn profile in one click. Free, no account, 100 lookups a day. WHAT IT DOES Open a LinkedIn profile, click the icon, get the person's work email address. The extension reads the name and employer from the page, finds that company's email domain in the official business register, works out the address pattern the company uses, and asks the mail server whether the mailbox exists before it shows you anything. The personal work address, not the info@ inbox. Every result is labelled Verified, Risky or Not found, so you always know what you are about to send to. HOW IT WORKS 1. Open a LinkedIn profile and click the extension icon. The name and employer are read from the page. On any other page, or when a profile is private, type the name and company yourself. 2. The employer is matched to its record in the official company register, and the email domain is taken from that record. Not from a scraped page, not from a URL someone guessed once. 3. The address is built in the pattern that domain actually uses: first.last, f.last, flast, first. 4. The mail server is asked whether that mailbox exists. Copy the address and go. WHAT THE LABELS MEAN Verified: the mailbox exists and the domain is not catch-all. Reliable for most Google Workspace and Microsoft 365 domains. Risky: the domain accepts mail for any address (catch-all), or the server would not confirm or deny. The address follows the company's own pattern, but expect a higher bounce rate. Roughly a third of corporate domains are catch-all and will always come back Risky. Not found: every format was rejected. The person has probably left, uses a different domain, or the company has no website on record. You can enter the website yourself and try again. WHY THE DOMAIN COMES FROM A REGISTER Most email finders start from whatever domain a crawler happened to associate with a company name. That breaks on holdings, trade names, local subsidiaries and companies that share a name with something bigger. This extension works the other way round. The employer on the LinkedIn profile is matched to a legal entity in official company registers: 375M+ companies, 200+ registers, 200+ countries. The email domain comes off that entity's record. You get the registered company behind the profile, not a best guess from a website. If the register has no website for that company, the extension can look it up in the top web results from your own browser. Chrome asks once for access to websites, and only then. WHO USES IT Sales and SDR teams building a list from LinkedIn without paying per credit. Recruiters reaching candidates outside InMail. Founders doing outbound by hand. Anyone who needs one address right now and does not want to sign up for a seat. LIMITS 100 lookups a day per install, resetting 24 hours after your first lookup. Looking up the same person twice counts once. No account, no credit card, no trial that expires. The daily cap exists to keep mail-server checks polite, not to upsell you. PRIVACY Only the company, the domain and the address found are logged. The person's name and LinkedIn URL are not stored. When the web-search fallback runs, it runs in your browser, with permission you grant once and can withdraw. You are responsible for how you use the addresses you find, including under GDPR. BEYOND ONE EMAIL AT A TIME Every result links through to the full company report: legal name, registration number, VAT number, registered address, status and group structure. If you need the same register data across a whole CRM instead of one profile at a time, CompanyData.com offers it as an API. Company enrichment fills in legal name, registration number, VAT, address, industry codes, size and parent company from the register, one call per record or the whole database on a schedule. See https://companydata.com/company-enrichment-api/ FREQUENTLY ASKED QUESTIONS Is it really free? Yes. 100 lookups a day, no account, no card. There is a paid API for volume, but the extension does not ask you for anything. How accurate is it? Verified results are reliable for most Google Workspace and Microsoft 365 domains, because those servers answer honestly about whether a mailbox exists. Catch-all domains cannot be verified by anyone, so those come back Risky rather than being passed off as confirmed. Does it work on companies outside the US? Yes. Coverage comes from 200+ official registers across 200+ countries, including the Dutch KVK, UK Companies House, German Handelsregister, French INSEE and the rest of the EU. What if the company is not found? Type the company website into the extension and it will use that domain directly. Does it work on private profiles? If LinkedIn will not show you the name, the extension cannot read it either. Type the first name, last name and company in yourself and it works the same way. Do I need a LinkedIn Sales Navigator seat? No. It reads the public profile page you already have open. Who is behind it? CompanyData.com, a B2B company data provider with 375M+ company records from official registers in 200+ countries. See https://companydata.com
