Frequently Asked Questions

Does it validate that emails are real?

It extracts addresses matching proper email syntax. Deliverability checks require sending infrastructure — use our cleaning guides next.

Are similar addresses like a@mail.com and A@mail.com merged?

Extraction is case-sensitive, so capitalized duplicates may both appear. Run Remove Duplicates on the result if you need case-insensitive merging.

Can it process a 100MB log file?

Yes, within the browser memory limit. For very large logs, split the file first and extract per part.
