About this Gig

I'll help you turn a messy, unreliable email list into a clean, validated one ready to use with confidence.

What this service includes:

Email format validation (catches malformed addresses)

Deduplication (case-insensitive catches "John@Gmail.com" and "john@gmail.com" as the same address)

Risk-account filtering (removes system addresses like abuse@, admin@, postmaster@)

Disposable domain filtering (removes temporary/throwaway email providers)

Clean output in CSV or JSON format

A detailed discard report listing every removed email and the exact reason why

This isn't a quick script thrown together I built and tested this tool with proper error handling, so a single malformed entry or a missing file never breaks the whole process. Every step is logged for full transparency.

You can see the working code here: https://github.com/SlinkierBook/Email-list-sorter

Send me your list in a .txt or .csv file, and I'll take care of the rest. Feel free to message me before ordering if you have a larger list or specific requirements.
