Is the email extractor really free?
Yes. No hidden costs, usage limits, or required upgrades. Use it as often as you need.
What's the maximum file size?
10 MB per file. You can upload multiple files in one session.
Do you store my data?
No. Files are processed in memory and discarded after extraction. We don't retain uploaded content or extracted emails.
Can I extract from PDFs?
Not currently. Convert PDFs to text first, then paste the content. Most PDF readers have a "Select All" and copy function.
How accurate is the extraction?
The pattern matching catches standard email formats with high accuracy. Unusual formats (quoted local parts, IP address domains) may be missed, but these are rare in practice.
What should I do after extracting?
Verify your list before sending emails. Invalid addresses hurt deliverability and waste resources. Try our email verification service to validate addresses.
