Email list cleaning service
Email list cleaning removes the addresses that will bounce or hurt your sender reputation: mailboxes that no longer exist, dead domains, typos, disposable addresses and duplicates. SimpleVerifier cleans a CSV with SMTP mailbox checks and returns separate valid, risky and invalid files, for $29.99 a month with no cap or a one-time pack from $9.
Lists decay on their own. People change jobs, companies change domains, and personal mailboxes are closed. A list that barely bounced a year ago can bounce far more today, and mailbox providers judge you on the bounces, not on the age of the list.
Cleaning is a self-service upload here, not a managed project. You keep control of the file, and you decide what to do with the risky group. The use-case guides explain which results to keep or drop for cold email, newsletters, ecommerce and more.

Lowest published route for cleaning one list of that size, read from each vendor's pricing page. Ours is the lower of the one-time packs and one month of Pro. Each vendor links to its comparison page, which records the date its prices were read. Check their site for current pricing before you buy.
What a clean removes
Invalid: the mail server said the mailbox does not exist, the domain has no mail servers, or the syntax is broken. These are the addresses that hard-bounce, and they should go.
Risky: the server would not confirm the mailbox, the domain accepts every address (catch-all), or the address is a role account. Disposable domains, 9,913 of them, are flagged too. Whether to send to risky addresses depends on the list; the catch-all guide covers the trade-off.
Valid: the mailbox was confirmed by its own server. That does not promise a reply or an inbox placement, but it removes the bounce.
How often to clean
A list that is still being added to, or that you send to every month, is worth re-checking before each large send. On a metered service each re-check is billed again, which is the main reason a flat plan exists. On Pro a re-check costs nothing extra, and results confirmed within the last 14 days come back from cache.
Common questions
- What is an email list cleaning service?
- A service that checks every address on a list and tells you which ones will bounce, which are risky, and which are confirmed, so you can remove the bad ones before sending.
- How much does email list cleaning cost?
- On SimpleVerifier, $29.99 a month with no cap, or $9 for 2,500 emails and $19 for 10,000 emails as one-time packs. Other vendors mostly charge per address; the table on this page compares one clean at three list sizes.
- Will cleaning my list remove spam traps?
- Partly. Verification removes dead addresses, and recycled spam traps are often old dead addresses that were reactivated, so cleaning old lists lowers the risk. No verifier can identify every trap, because a trap is built to look like an ordinary mailbox.
Clean your list
Pro is $29.99 a month with no cap on verifications: CSV uploads, the API, the Google Sheets add-on and the email finder are included, and you can cancel any time. For a single list, one-time packs are $9 for 2,500 emails or $19 for 10,000 emails.
