Email verification, end to end.
Drop your list in, get a clean one back. Use it in your email tool, in your signup form, or wherever else email lives in your business. Here's what comes in the box.
What CleanMyList does
Five jobs, done well, on every list.
You don't need to be a deliverability expert. You drop your list in, and we handle the rest. Here's what we're doing while you make coffee.
Catches the obvious bad ones in milliseconds.
Typos, fake domains, addresses that go nowhere. We filter those out first so you're not paying us to check things that were never going to work.
- Spots typos like 'gmial.com' and 'yhaoo.com'
- Checks the domain actually exists
- Handles international email addresses
Quietly checks if the mailbox is real.
We talk to the mail server and ask if the address exists. No emails get sent. No one in your list gets pinged. Your sender reputation stays exactly where it is.
- No actual emails get delivered
- No risk to your sender reputation
- Works across thousands of email providers

Honest about the addresses that are hard to call.
Some companies accept email at any address, real or not. Other tools throw their hands up and call those 'risky'. We give you a real score so you know which ones are probably fine and which ones to skip.
- Confidence score, not a coin flip
- Based on how those domains have actually behaved
- You set your own rules on what to send

How you use it
One service, in whatever shape your workflow needs.
- Bulk lists
- Drop in a CSV up to one million addresses. We start working immediately and stream the good ones back as we find them.
- Real-time checks
- One API call in your signup form catches typos and fake emails before they hit your list.
- Manual re-runs
- Re-check a list before an important send. Each run is separate, billable, and exportable.
- Reports for your team
- Every run comes with a downloadable report showing what got cleaned, why, and how much you saved.
- Workspaces for teams
- Separate accounts for different brands or clients. Each one keeps its own list and its own credit pool.
Things you don't have to worry about
Boring but important.
- Your data stays yours.
- We never sell it, never share it, never use it to train anything. Your list is encrypted and deleted within 30 days of the run.
- GDPR-aligned, encrypted end to end.
- Your list is handled with access controls, encryption, and customer-facing privacy terms your team can review.
- We tell you the score, and we update it.
- Every result carries a score, reason, model version, and timestamp so you can audit what happened later.
