Paste raw text, HTML source, logs, or CSV rows below to instantly extract all valid email addresses, deduplicate them, filter out role or free webmail accounts, and verify their live SMTP deliverability in 1 click.
Extracting email addresses from unstructured directories, event attendee exports, raw HTML DOM snapshots, or SMTP server logs inevitably captures syntax noise: CSS/retina image strings (banner@2x.png), departmental role inboxes (abuse@, postmaster@, noreply@), duplicate Gmail plus-tags, and deactivated employee mailboxes. Importing an unverified extraction straight into HubSpot, Instantly, Smartlead, or Mailchimp can push your hard-bounce rate above 5% and trigger immediate domain suspension.
Automatically strips trailing punctuation, HTML mailto: prefixes, angle brackets, asset filenames (.png, .webp, .woff2), and obfuscations like [at] and [dot].
Filter out personal @gmail.com, @yahoo.com, and @hotmail.com addresses and 25+ role prefixes with one click when building B2B outbound sequences.
Connects directly to our 7-Layer Smart SMTP engine to verify MX records, catch-all policies, and mailbox existence before you export to CSV.
Paste raw HTML DOM source, mailserver logs, or unstructured CSV text into the input panel. The parser strips mailto: prefixes, angle brackets, and retina asset false positives (@2x.png, @3x.webp) and outputs a deduplicated list ready for CSV/TXT export.
When Normalize Gmail dots/plus is enabled, addresses such as alex.founder+promo@gmail.com and alexfounder@googlemail.com are canonicalized to alexfounder@gmail.com so you never email or pay to verify the same Gmail inbox twice.
Yes. Toggle Exclude role accounts to strip 25+ shared departmental prefixes (info@, admin@, support@, billing@, abuse@, postmaster@) and toggle B2B only to exclude consumer domains (@gmail.com, @yahoo.com, @hotmail.com, @icloud.com).
Unstructured text and scraped web pages typically contain 18% to 35% defunct mailboxes, syntax artifacts, or spam traps. Running live 7-Layer Smart SMTP verification via our Bulk Email Cleaner prevents 550 hard bounces and protects your domain reputation.
Whether you are consolidating event attendee notes, parsing raw server mail logs, auditing messy HTML source code, or extracting prospect addresses from unstructured text documents, manually copying email addresses is slow and error-prone. Worse, many online email extractors upload your confidential text to remote servers.
The KaijuVerifier Email Extractor executes 100% locally inside your browser using a high-speed RFC 5322 regular expression engine paired with automatic de-obfuscation (converting anti-scraper patterns like john[at]company[dot]com or john (at) company (dot) io back into standard john@company.com syntax). It automatically lowercases, trims trailing punctuation, deduplicates addresses in O(N) time, and lets you send the extracted list directly into our 7-Layer Smart SMTP Bulk Verifier with one click.
