📧
Most ESPs charge per subscriber and reject duplicates anyway. Dedupe before importing to save credits and prevent errors.
💡
Enable "Ignore case" — Alice@Example.com and alice@example.com are the same address.
🎯
Use "Count occurrences" mode first to see if you have a few duplicates or thousands — gauges the data quality.
