Company Domain Extractor
Turn mixed email addresses, website URLs, and lead-list text into a clean, deduplicated list of company domains ready for research and CRM preparation.
Extracted Company Domains
Use the output as a preparation list, then review each company and domain before outreach.
Processing happens in your browser. Results identify text patterns only and do not verify company ownership, legitimacy, website availability, mailbox existence, or deliverability.
How to Use the Results
Treat the extracted list as a structured starting point for company research and lead cleanup.
Domains are lowercased, stripped of paths and common prefixes, and prepared in a consistent format.
Common consumer and disposable email providers can be removed so company-domain research stays focused.
Open or check each domain before connecting it to a company record, contact, or outreach campaign.

Frequently Asked Questions
Understand what the extracted domains can and cannot tell you.
What information can I paste into the Company Domain Extractor?
You can paste email addresses, website URLs, plain domains, or mixed lead-list rows. The tool looks for recognizable email and web-domain patterns in each line.
What happens to Gmail, Outlook, and other public email domains?
When the public-email filter is enabled, common consumer and disposable email domains are excluded from the company-domain results and counted separately.
Does a domain prove that the lead belongs to a company?
No. A domain is only a formatting clue. Review the company website and public business information before relying on it for research or outreach.
Does this tool check whether a website or email address works?
No. It extracts and standardizes domain text. Use the Domain Health Checker for public website and email-domain configuration signals.
Is my lead data uploaded or saved?
The extraction runs in your browser. TradeGoAI does not save the pasted lead data or the extracted list.
