What cleaning finds
What gets flagged when you clean your email list.
Every row is checked and labelled. Nothing is silently dropped: the label tells you why an address should go, or why it deserves a second look.
Disposable inboxes
Throwaway addresses from temporary-mail services. They often pass a form but stop working within hours or days.
Disposable: YesRole addresses
Shared inboxes such as info@, sales@ or support@. They can be real, but they rarely belong to the person you meant to reach.
Role: YesCatch-all domains
Domains that accept any address. On supported Google Workspace and Microsoft 365 domains the mailbox itself is checked; otherwise the row stays flagged as catch-all.
Accept All: YesTemporary replies
Greylisting and slow servers. These rows stay Unknown and are checked again in the background instead of being thrown away as invalid.
State: UnknownReason: GREYLISTEDDeliverable
The mailbox exists and accepts mail. These rows go straight into the clean list.
State: DeliverableScore 80–100What “clean” means in the export

Only addresses with the highest delivery confidence. The safest choice for a cold or long-unmailed list.
Maximum reach: score 60+
Adds borderline addresses, such as many role addresses, for sends where reach matters more than a perfect bounce rate.

Your data
What happens to the list you upload.
Before you upload customer data, you should know exactly where it goes. The short version: your list is used to verify your list, and nothing else.
Used only for verification
The addresses and columns in your file are processed to produce your results. They are not sold, rented or shared for marketing.
No email is ever sent
Verification checks the domain and the mail server without delivering a message, so nobody on your list is contacted.
Kept only for you
Results stay in your account so you can download them again. Delete a list from your dashboard when you are done, and ask support if you want the file erased from our storage too.
Private to your account
Uploads and downloads travel over HTTPS and are visible only when you are signed in to your own account.
Payments through PayPal or USDT
Card details are entered with PayPal, never on this site. Purchased credits do not expire.

Email list cleaning FAQ
Clean your list with the important questions answered.
What does email list cleaning remove?
Cleaning finds the addresses that would bounce or hurt a send: mailboxes and domains that do not exist, domains that no longer accept mail, and syntax errors. It also flags disposable inboxes, role addresses such as info@ and sales@, and catch-all domains, so you decide whether to keep them. Nothing is deleted from your file: every row gets a score and a state, and the export filter decides what goes into the clean list.
How do I get only the clean addresses?
Choose the “Maximum deliverability” export (score 80 and above) for the cleanest send list, or “Maximum reach” (score 60 and above) to keep more borderline addresses. “Undeliverable” exports only the addresses to suppress, which is handy for updating your CRM or email platform.
Will cleaning throw away addresses that are actually fine?
It is built not to. When a mail server answers with a temporary delay, the address stays Unknown and is re-checked automatically instead of being marked invalid. On supported Google Workspace and Microsoft 365 catch-all domains the mailbox itself is checked when a definitive answer is available.
Can I put the cleaned list back into my email platform or CRM?
Yes. Your original columns (name, company, source, tags and so on) stay attached to every row, so the export can be imported back into Mailchimp, Klaviyo, HubSpot or any tool that accepts CSV.
How often should I clean my email list?
Before a send to contacts you have not mailed for a while, after importing contacts from events or forms, and before moving a list to a new sending platform. Lists decay as people change jobs and mailboxes are closed, so older segments benefit most.
What does email list cleaning cost?
One credit per email, and purchased credits never expire. New accounts include free credits, so you can clean a sample of your list before buying. The calculator above shows the package for your list size.
Does cleaning send an email to my contacts?
No. ValidEmail checks deliverability signals with the mail server without delivering a message, so nobody on your list is contacted.
