🧹 Email List Cleaner
Clean your outreach list before sending. Remove duplicates, broken addresses and disposable domains in one click.
About this tool
Sending to bad addresses raises your bounce rate and can damage your sender reputation. Cleaning the list first protects your domain and saves time.
This tool removes duplicates, checks basic syntax, flags disposable email domains, catches common typos such as gmial.com and can optionally drop role addresses like info@ or admin@. It runs in your browser, so your list is never uploaded. Note that it cannot confirm that a mailbox really exists. For that you need a full verification service.
How to use it
- Paste your emails in any format.
- Tick the box if you also want to remove role addresses.
- Click Clean.
- Copy the clean list or download it as CSV.
Tips for better results
- Keep role addresses if you target small businesses.
- Verify cleaned lists with an email verification service before large campaigns.
- Warm up new sending domains slowly.
- Always include an unsubscribe option in bulk campaigns.
Frequently asked questions
Does this verify that the mailbox exists?
No. It checks format and common problems only. Use a verification service for deliverability checks.
Is my list stored anywhere?
No. Everything is processed in your browser.
What is a role email?
An address for a function rather than a person, such as info@, support@ or sales@.
