Clean Email List — frequently asked questions
Is Clean Email List really free?
Yes. Clean Email List is completely free forever on Sada Files. There are no fees, subscriptions, advertisements, or daily row limits.
Do I need an account to clean my email list?
No. There are no accounts or logins for end users on Sada Files. You can upload and clean your contact list immediately without creating an account.
Is my email list uploaded or saved anywhere?
No. Clean Email List executes 100% inside your browser using client-side JavaScript. Your confidential customer and contact lists are never uploaded to any remote server or stored in any database.
What cleanup steps does this tool perform?
The tool trims leading and trailing whitespace, converts all email addresses to lowercase, removes duplicates, excludes malformed/invalid addresses, and optionally filters out role-based accounts (like `support@` or `billing@`) or disposable temporary email domains.
What file formats can I clean?
You can upload contact lists in plain text (`.txt`) or comma-separated values (`.csv`) format, and export the sanitized results directly back to `.csv` or `.txt`.
How fast is the cleaning process?
Because processing happens locally on your computer using optimized client-side routines, even lists with tens of thousands of emails clean in a fraction of a second.
