Email Domain
Extractor
Extract emails, then intelligently group, filter, and clean them by domain. Remove disposable providers, exclude free email services, and focus on the contacts that matter.
Open Domain ExtractorHow Domain Filtering Works
Extract Emails
Start by extracting emails using any mode: paste text, fetch a URL, or crawl a website. All extracted emails are displayed in the results table.
Review Domain Breakdown
The stats dashboard shows which domains appear most frequently in your results. You can see at a glance if your list is heavy on free providers (Gmail, Yahoo) or focused on corporate domains.
Apply Domain Filters
Use the include/exclude filter to focus your results. Add domains to the include list to keep only corporate emails, or add free providers to the exclude list to remove them.
Export Clean List
Once filtered, export only the visible emails. Your CSV, TXT, or clipboard export will respect all active filters — only the emails matching your domain criteria are included.
Filtering Capabilities
Domain Include & Exclude
company.com startup.io gmail.com yahoo.com Add domains as pill-style tags. Include mode keeps only matching domains. Exclude mode removes matching domains. You can combine both for precise targeting.
Four-Tier Validation
Each email is categorized: valid personal address, role-based generic address (info@, support@), disposable domain, or invalid format. Filter by category to keep only what you need.
Common Domains to Filter
When building a targeted B2B email list, you typically want to exclude free email providers and focus on corporate domains. Here are the most common domains to filter:
Common Excludes (Free Providers)
Common Excludes (Role Prefixes)
Use Cases for Domain Filtering
B2B Prospecting
After extracting emails from a target company's website, filter to keep only @company.com addresses and exclude generic role-based addresses to build a list of individual contacts.
Email List Cleanup
Paste your existing email list, then use the disposable domain filter and role-based filter to identify and remove low-quality contacts before your next campaign.
Market Research
After crawling multiple company websites, use the domain breakdown to understand the landscape — which companies have the most exposed emails, and their organizational patterns.
CRM Data Hygiene
Export your CRM contacts, paste them in, and use domain grouping to identify contacts using personal email addresses that should be updated to corporate addresses.
Frequently Asked Questions
What does 'domain extraction' mean?
Domain extraction refers to grouping, filtering, and analyzing extracted emails by their domain — the part after the @ symbol. For example, grouping all @company.com emails together, or filtering out all @gmail.com addresses.
Can I exclude free email providers like Gmail and Yahoo?
Yes. The domain filter has an exclude mode where you can add domains like gmail.com, yahoo.com, hotmail.com, and outlook.com. All emails from those domains will be hidden from your results and excluded from exports.
Can I keep only emails from specific domains?
Yes. The include mode lets you specify which domains you want to keep. For example, if you only want emails from company.com and startup.io, add those to the include list and everything else is filtered out.
How does disposable domain detection work?
The extractor maintains a list of known disposable and temporary email providers (like Mailinator, Guerrilla Mail, 10minutemail, etc.). Emails from these domains are flagged so you can easily remove them from your clean list.
What are role-based email addresses?
Role-based addresses are generic emails like info@, support@, admin@, sales@, and webmaster@. They go to a department or role rather than a specific person. The validation engine identifies these so you can filter them if you want personal contacts only.
Can I see how many emails come from each domain?
Yes. After extraction, the stats dashboard shows a domain breakdown — the number of unique emails found per domain, sorted by frequency. This helps you understand the distribution of your extracted list.
