An email extractor and an email finder both end with addresses in hand, but they work in opposite directions. An extractor pulls addresses that already appear in text, files, or HTML you provide. A finder starts from a person or company and tries to discover or predict an address that isn't written down anywhere.
The difference is discovery versus extraction. Extraction is deterministic — the addresses are already there. Finding is probabilistic — it guesses patterns like first.last@company.com and verifies them. Each fits a different stage of list building.

When to use Email Extractor
You already have content containing addresses.
You want instant, reliable extraction from text or files.
You're cleaning exports or mining documents.
When to use Email Finder
You know who you want but not their address.
You're prospecting named individuals at companies.
You're comfortable predicting and then verifying patterns.
Verdict
Use an extractor when the addresses already exist in your material — it's fast and certain. Use a finder when you need to reach a specific person whose address isn't published, generating likely patterns and verifying them. In practice they chain together: find or predict candidate addresses, then extract and dedupe them, and always verify before sending.
