Paste emails, upload a file, or drop a CSV — get real-time DNS verification and automatic classification into Office365, G Suite, Business, Residential, Educational & more. Track any keyword with Smart Categories.
Four simple steps from raw email list to perfectly categorized, export-ready results.
Paste raw text, paste from spreadsheets, or upload TXT/CSV files. Our parser automatically detects and extracts all valid email addresses — even from messy, unformatted data.
Every email's domain is queried in real-time via DNS MX lookup. We identify which mail server the domain points to — this is how we determine Office365, G Suite, and more.
Results are classified into 7 categories using MX pattern matching and domain intelligence. Add Smart Categories — enter keywords like finance, payroll, admin — and every matching email is instantly tracked and available for separate export.
Download each category or Smart Category separately with auto-numbered filenames. Choose TXT, CSV, JSON, or XLS, and pick your separator: newline, comma, pipe, semicolon, tab, or custom.
Every email is assigned to exactly one category using real-time DNS analysis and domain intelligence.

Go beyond the 7 built-in categories. Define your own keyword-based filters to track and export exactly the emails you care about.
Click the Smart Categories panel in the sidebar. Type comma-separated keywords — for example: finance, payroll, account, budget — and give your category a name.
As emails are verified, any address whose local part or domain contains one of your keywords is instantly added to your Smart Category — shown as a golden badge in the results table and a dedicated tab in the category bar.
Each Smart Category can be exported independently as TXT, CSV, JSON, or XLS. You can have unlimited Smart Categories running simultaneously — perfect for segmenting department emails, role-based filters, and competitor domain tracking.
Built for marketers, developers, and data professionals who need fast, accurate email list processing.
Batch DNS verification processes thousands of emails per minute with concurrent lookups and intelligent caching to avoid duplicate DNS queries.
Live MX record lookups classify each domain accurately. Not just a domain list — actual DNS querying to detect mail server providers.
Export as TXT, CSV, JSON, or XLS. Choose your separator: newline, comma, pipe, semicolon, tab, or custom. Export any Smart Category or standard category separately.
Instantly search within results by email or domain. Sort columns and paginate through large datasets with 100 rows per page.
10 built-in themes including the signature Gold style. Your preference is saved via browser cookies and persists across sessions.
No account needed. No email storage. No logging. Your data is processed and immediately discarded — complete privacy by design.
Drag and drop or upload TXT, CSV, and other plain text files. Our smart parser extracts emails from any format automatically.
Enter comma-separated keywords like finance, payroll, account — any email matching those keywords in its address or domain is auto-classified into your custom Smart Category, ready for separate export.
Processing state is saved automatically every 3 seconds. Refresh, close the tab, or lose connection — your job resumes exactly where it left off with a single click.
Automatically deduplicate your list before processing. Toggle off to keep all occurrences including duplicates if needed.
Works on desktop, tablet, and mobile. Process email lists from any device with the same power and accuracy.
Segment your list into Office365, G Suite, and public providers before campaign send. Improve deliverability by cleaning dead emails before you import.
Validate user-submitted email lists, detect free-tier signups vs. business emails, and route support queries by mail provider.
Analyze the composition of email datasets — what percentage is Office365? How many are dead? Export clean JSON or CSV for your pipeline.
Quickly score leads by email provider. Business and Office365 emails often indicate company accounts — separate them from consumer signups.
Audit exported email lists. Identify which domains are using which mail providers across your organization or partner directories.
Identify and separate .edu and institutional emails from consumer accounts in survey or study participant lists.
EpicMailExtractor supports up to 100,000 emails per session, completely free with no registration or signup required. Simply paste your list or upload a file.
Our system performs real DNS MX record lookups for each domain. Domains whose MX records include mail.protection.outlook.com or olc.protection.outlook.com are classified as Office365 — this catches all Microsoft 365 tenants, including custom business domains using Microsoft email hosting.
We check MX records for Google's mail server patterns, specifically aspmx.l.google.com and related alt records (alt1–alt4.aspmx.l.google.com). Any domain resolving to these servers is classified as G Suite/Workspace.
Domains that return no DNS records, have no A or MX records, or fail to resolve are classified as Bad/Dead. These are typically expired domains, invalid emails, or typos.
Yes. Toggle off the "DNS Verify" option to use fast local classification only (based on known domain databases). This is faster but cannot detect corporate domains using Office365 or G Suite.
You can export as plain text (TXT), CSV with headers (Email, Domain, Category, MX), or JSON. You can choose separators: newline (default), comma, pipe |, semicolon ;, tab, or any custom character or string.
No. Your email data is never stored, logged, or shared. DNS lookups are performed server-side for accuracy but no email or domain data is retained after the request completes.
Yes. Drag and drop any TXT, CSV, or plain text file into the upload zone, or click to browse. Our parser automatically extracts all valid email addresses from the file content.
Yes. By default, duplicate emails are removed before verification. Toggle the "Keep Duplicates" option to preserve all occurrences.
Exported files are auto-named with the format: EpicMailExtractor_v1.0_[category]_[YYYYMMDD_HHMM].[ext] — for example, EpicMailExtractor_v1.0_office365_20250501_1430.csv
