A cleaned list sorts every address into one of four results.
The mailbox exists and accepts email, so it is safe to send.
The domain accepts every address, so send these in a small separate batch.
The mailbox does not exist, so drop the address.
The mail server gave no definitive answer, so check it again later.
We compared them on five things that decide the cost of cleaning a list.
- What the vendor's own page charges for the pack that fits your list.
- What happens to unknown results and duplicates: whether they use a credit.
- How you can try it free, and how much of a list the free start covers.
- Whether credits expire.
- Whether the same account can send the campaign once the list is clean.

People ask these questions about cleaning an email list.
What is the best email list cleaning service in 2026?
We pick Emailchaser: its list cleaner is free in your browser, a paid job verifies up to 50,000 addresses, a second, independent provider checks again every address the first one does not reject, and 1,000 addresses cost $1.70 to $3.40 in checks. ZeroBounce, Bouncer, Emailable and Kickbox do not charge for unknown results.
How do I clean an email list for free?
Emailchaser's bulk email verifier cleans a list free in your browser, up to 10,000 rows: duplicates removed, syntax checked, and role and free-provider addresses flagged. It also gives 3 free live checks a day with no signup. ZeroBounce gives 100 free credits a month, Emailable 250, and Bouncer, Kickbox, EmailListVerify and DeBounce 100 each.
How much does it cost to clean an email list?
On Emailchaser the checks cost $1.70 to $3.40 for every 1,000 addresses (one or two checks an address at $0.0017 each), on a plan from $47 a month. From the vendors' own pages, 10,000 addresses are $27 on EmailListVerify, $60 on Bouncer and $70 on Kickbox. Prices were read on 5 November 2026.
How often should I clean my email list?
Clean a list before every new campaign and before you import a list that has sat for months. People change jobs and mailboxes close, so an address that worked last quarter can bounce today.
What happens to unknown results when I clean a list?
An unknown result means the mail server did not give a definitive answer in time, often on purpose, and it is not the same as invalid. ZeroBounce and Bouncer say they never charge for them, Emailable and Kickbox refund the credit. Check unknown addresses again later.
Do I need to upload my list to clean it?
Not for the first pass. Emailchaser's free list cleaner reads your file in your browser, so the list is never uploaded. Verifying addresses against live mail servers is the step that runs on the service.
Do cleaned-list credits expire?
It depends on the vendor. Emailable, Bouncer, EmailListVerify's pay-as-you-go credits and DeBounce say they never expire, and ZeroBounce's do not while a ZeroBounce ONE subscription is active. Emailchaser bills per check, so there are no credits to expire.

SEE REVIEWSP.s. these are actually real reviews (not fake G2 reviews) 🙂
“Btw thanks for your continuous help, best support ever! It means a lot as when I understand how the tool works, esp. In problematic situations, and And what it can do and cannot so from the start, I have more trust. There’s nothing worse for a user than what Smartlead does: lots of great features that don’t really work, including crucial ones for a sequencer like auto fallback to connected accounts when account gets disconnected (doesn’t have to get back to the original one after reconnection, no one expects miracles, just a solid infra delivering on its specs - not promises), plus their low quality support when the issues are revealed.”
“Got my first reply with Emailchaser :)”
“We've recently upgraded to the premium plan to increase our sending volume. Just wanted to say thanks for such an awesome platform and the support you've already given in getting us started.”
