Email normalizer
Normalize email addresses to a standard format for easier comparison
Note: This tool normalizes email addresses by converting them to lowercase, removing Gmail dots, removing plus aliases (e.g., user+tag@domain.com → user@domain.com), and removing duplicates. This helps with email deduplication and data cleaning.
