Email List Cleaner

This is a free and open source, privacy-first email address list validation tool where the processing happens inside your own browser and no one, including myself, get access to your email addresses. It's all open source, so you don't need to trust my word that this is how it works, you can verify exactly how it works.

Some of its other key features:

• Supports detecting and removing disposable and one-time-use email addresses.
• Supports detecting and removing role-based email addresses, such as info@example.com
• Supports detecting and removing unlikely valid email addresses, such as nospam@example.com
• Supports detecting and removing duplicate email addresses, with advanced support for special email domains. For example, with gmail, email addresses john.smith@gmail.com and johnsmith@gmail.com are the exact same email inbox. This tool knows this and other similar edge cases and supports duplicate checking supporting these as well.
• Supports dark mode and displays pretty charts and statistics after your analysis is completed. Everything looks better in a chart.
• The logo features a cat.
