How to use this tool

Paste text containing email addresses to extract the part before @ automatically. Optionally change sorting or add a suffix, then copy the result.

Understanding the result

Extract addresses separated by newlines or commas, or embedded in text. Domain statistics show how many matches belong to each domain.

When to use it

Prepare a test-name list or inspect local parts from addresses you are authorized to process.

Practical tips

Identical local parts at different domains can belong to different people. Do not use the extracted name as identity verification.
