How it works
Email list cleaning in three steps.
No setup, no engineering, no quotas to argue about. Drop your list in, watch it work, send to people who actually exist.
- 01
Drop your list in
Drag in a CSV or paste a list. We never touch your original.
- 02
Watch it clean
Good addresses light up green, bad ones turn red. Each one comes back with a one-line reason in plain English.
- 03
Send to real people
Download the clean list, or push it straight back into your email tool. Bad addresses get tagged so they stay out of your next send.
What you get
Six ways CleanMyList saves your next campaign.
You don't need to know how it works. You just need it to work. Here's what changes when you start cleaning your list.
- Catches the obvious junk first
- Broken formatting, common typos, and domains that cannot receive mail. Filtered before we move on to the slower checks.
- Asks the receiving server
- We quietly check whether the server will accept the address. No emails get sent, no one gets bothered, and your sender reputation stays clean.
- Honest about the tricky ones
- Some emails are hard to call. We show the score and warning signs so you can decide which ones to send to and which to skip.
- Fast, even on huge lists
- Drop in a CSV and watch the verdicts stream back as the run works through each address.
- Stops bad emails at signup
- One line of code in your signup form, and typos or fake addresses never make it into your list in the first place.
- Re-run a list when it ages
- Email addresses go stale. Re-run a saved list before your next campaign and keep the new verdicts separate from the original file.
What we check
A careful check for every email. One clear answer.
You don't see any of this. We do the checks and give you a clear label, score, and reason. Curious what runs in the background? Here it is.
Check 01
Does it look right?
We catch broken formatting and suggest fixes for common domain typos.
Check 02
Is it a throwaway address?
We flag known temporary email services that are built to disappear.
Check 03
Is it a shared inbox?
We spot addresses like info@ and support@ so you can decide whether they belong in your campaign.
Check 04
Can the domain receive mail?
We check that the part after the @ has a working mail server.
Check 05
Any domain warning signs?
When available, we check live warning lists for domains linked to abuse or only recently seen.
Check 06
Will the server accept it?
We ask the receiving server about the address without sending an email.
Check 07
Does the server accept everything?
We try a made-up address to spot catch-all domains where every mailbox appears valid.
Check 08
What should you do?
We combine the results into a clear label, score, and plain-English reason.
From the teams we work with
The kind of results that make Mondays better.
“CleanMyList caught addresses our old process missed before the first send. The export made it obvious what to suppress and what to keep.”
Yara Behrens
Head of Lifecycle, Bramble
“I've used three other tools. This one is faster, easier to use, and costs less. The reasons it gives on every verdict alone save me an afternoon every month.”
Devran Acar
Founder, Cargo Collective
“Cleaned our campaign list before launch and gave us clear reasons for every risky address. Worth every cent.”

Yes. We never send an actual email when we check. We ask the receiving server whether it will accept the address, then stop before a message is sent. Nothing lands in anyone's inbox.
A list of 10,000 emails takes around a minute. 100,000 takes about six. You can watch the good ones come back in real time and start using them before the run finishes.
We never sell it, share it, or use it to train anything. Your list is encrypted, kept only as long as you need it, and deleted after 30 days. That's it.
Yes. Drop one line of code into your signup or checkout form and we'll catch fake or mistyped emails before they hit your list. Most teams set it up in an afternoon.
