description

Emailsherlock Chrome Extension is a free tool to verify email addresses directly in your browser. It checks the email syntax, looks for typos and checks if the email address really exists. Verify while browsing the web and copy-paste email addresses from any website.

You can link the Widget to your Emailsherlock Account

Verify any email address instantly, directly in your browser. EmailSherlock is a free Chrome extension that checks email syntax, detects typos, and confirms whether an email address actually exists — without leaving the page you're on.
Whether you're in sales, recruiting, marketing, or just want to make sure your message reaches the right inbox, EmailSherlock saves you time and protects your sender reputation.

What EmailSherlock does:
• Email syntax check — instantly flags invalid formats (missing @, wrong TLD, etc.)
• Typo detection — catches common mistakes like "gmial.com" or "outloook.com" before you hit send
• Email existence verification — checks whether the address is real and reachable via MX record lookup
• Copy-paste support — verify any email you find while browsing, directly from any webpage
• Account integration — link the extension to your EmailSherlock.com account for a full verification history

Who is EmailSherlock for?
Sales professionals — Reduce email bounce rates before reaching out to prospects. A valid email list means more messages delivered and better campaign results.
Recruiters — Verify candidate email addresses on the spot while browsing LinkedIn, job boards, or company websites. No more failed outreach.
Email marketers — Keep your mailing list clean and improve deliverability. Lower bounce rates mean better inbox placement and protected sender scores.
Developers & freelancers — Quickly validate email inputs on contact forms, signups, or client data without switching tools.
Anyone who sends important emails — Make sure your message actually reaches someone before you hit send.

How email verification works:
EmailSherlock performs a multi-step validation process every time you check an address:
• Syntax validation — checks the format (correct use of @, valid characters, proper domain structure)
• Domain check — verifies the domain exists and has valid DNS records
• MX record lookup — confirms the domain is configured to receive emails
• Mailbox existence check — pings the mail server to verify the specific address is active
This layered approach gives you a much more accurate result than a simple format check alone.

Why email validation matters:
Sending emails to invalid addresses increases your bounce rate, which damages your sender reputation with providers like Gmail, Outlook, and Yahoo. A high bounce rate can result in your emails being flagged as spam — or blocked entirely.
EmailSherlock helps you catch bad addresses before they become a problem, so your emails get delivered, your reputation stays intact, and your outreach performs better.

Free to use, right in your browser:
EmailSherlock is completely free. No account required to get started. Install the extension, click the icon, paste or type an email address, and get an instant result.
For users who want to save and manage verification history, linking the extension to a free EmailSherlock.com account unlocks additional features.

Privacy-first design:
EmailSherlock only processes the email addresses you actively submit for verification. The extension does not track your browsing, read your emails, or collect any personal data beyond what is needed to perform the verification. Full details are in the privacy policy on emailsherlock.com.
