Clean an email list in one pass
Paste a list and strip out invalid addresses, duplicates and role accounts (info@, noreply@) in one go — then lowercase and sort. You control every pass, and it all runs in your browser. No sign-up.
Why clean your email list?
A raw list gathered from exports, sign-up forms and merged spreadsheets is rarely ready to send to. It carries typos and malformed addresses, the same person listed several times in different cases, and generic mailboxes like info@ and noreply@ that hurt engagement. Cleaning the list before you import it lowers your bounce rate, protects your sender reputation, and can cut costs on tools that bill per contact.
What this cleaner does
- Removes invalid addresses — anything that isn't a well-formed email.
- Removes role accounts — info@, support@, sales@, noreply@, admin@ and similar.
- Removes duplicates — case-insensitive, so

- Sorts A→Z when you want it.
Each pass is optional and shows exactly how many addresses it removed, so you always know what changed.
Part of a simple workflow
Cleaning is usually the last step. Start with the email extractor to pull addresses out of messy text or a page, validate them to see what's wrong, then run them through the cleaner here for a final, deliverable list.
Frequently asked questions
How do I clean an email list?
Paste your list into the box on the left. The cleaner runs every pass at once — removing invalid addresses, role accounts and duplicates, then lowercasing (and optionally sorting) — and shows the finished list on the right with a breakdown of what was removed. Then copy or download it.
What is a role account, and why remove it?
Role accounts are generic, shared mailboxes like info@, support@, sales@, noreply@ and admin@ — addresses that belong to a function rather than a person. They tend to have low engagement, higher complaint rates, and often can't be emailed for marketing under anti-spam rules. Removing them improves deliverability and keeps your list focused on real people. You can toggle this off if you want to keep them.
Which cleaning steps can I control?
Each pass is a toggle: remove invalid addresses, remove role accounts, remove duplicates, force lowercase, and sort A→Z. Turn any of them on or off and the result updates instantly, with counts for how many addresses each pass removed.
Is my list uploaded anywhere?
No. All cleaning happens locally in your browser using JavaScript. Your list is never uploaded, stored, or logged — nothing leaves your device. You can even go offline and it keeps working.
Can I export the cleaned list?
Yes. Copy the whole cleaned list to your clipboard, or download it as a .txt or .csv file, ready to import into your email or CRM tool.
