Five steps, from the file you upload to the bounce rate that shows up in your sending account.
01
Start with the export you already have.
Drop in a CSV or an Excel file and pick the column that holds the addresses. There is no template to match and no fields to map.
CSV and Excel, in any column order
Duplicates are dropped before you are billed
Every other column comes back untouched
02
We ask the mailbox instead of guessing.
Each address goes to its own receiving server for a real answer. Your contacts hear nothing, your sending domain stays out of it, and every row comes back with the reason behind its result.
A reason on every row, not just a score
Unknown results are free, you pay for answers
03
The group other tools give up on.
Catch-all domains accept mail for every address, so most verifiers hand the whole group back as risky and leave the decision to you. We turn a large part of it into real answers.
Around half of the group comes back answered
What stays unresolved is labelled, never passed off as valid
04
Download a list you can send today.
Every row comes back with its result and the reason behind it, and your original columns stay exactly as they were. Export the clean group on its own or take the whole file.
One file, every original column kept
Filter and export any group on its own
05
Your bounce rate follows.
This is the part that shows up in your sending account. Campaigns sent from a verified list run under 1% bounce, which is what keeps your domain out of trouble with the inbox providers.
Measured on live cold email campaigns
Fewer hard bounces, so your sender reputation holds

Every result, and what to do with it.
Nine outcomes, each one telling you whether to send, look closer or take the address out.

Recovered catch-all
The domain accepts everything, and we still worked out that a real mailbox is behind it. Counted as deliverable.

Role address
A shared inbox like info@ or sales@. It receives mail, but a person rarely reads it and replies are unlikely.

Catch-all
The domain answers yes to every address and we could not resolve this one. Send only when the contact matters.

Antispam block
A security gateway sits in front of the mailbox and refused to answer. The address may be fine, but it is guarded.

Unknown
The server would not give a straight answer. We mark it instead of guessing, and it never touches your balance.

Disposable
A throwaway address from a temporary mail service. It works today and is gone long before your follow up.

Do not mail
The mailbox exists but should not get campaigns, like a full or disabled account. Sending costs more than it earns.

Invalid
No mailbox, no domain, or a broken address. These are the rows that turn into hard bounces.
