Wiza export to email list: risky addresses marked, repeats removed
In short: Reads a Wiza CSV, reads the email_status column (valid or risky), sets aside invalid and role addresses, marks risky ones, merges repeats and flags webmail, typos and off-domain emails. Limit: Wiza doesn't publish every column name of its export; the email, status and name columns are found by name from an inferred list, so check the notes above the result.
Download the list from Wiza and upload the CSV here. The email_status column is read: valid addresses are kept, risky ones are marked so you can hold them back, role addresses and repeats are set aside, and addresses on a domain other than the company website are flagged. Then check the clean file live before the first send.

How do I check the Wiza leads before the campaign starts?
- Download the clean list here.
- Upload it at /verify. Every address gets a live mailbox check, and valid, risky and invalid download as separate files; catch-all domains are marked. The first 100 email checks are free with a Google sign-in, no card.
- Send to the valid file first. Hold the risky and catch-all part back or send it slowly.
How do I clean a Wiza export before sending?
- In Wiza, open the list and choose Download. Pick Valid, Risky or All; the CSV has an email_status column saying valid or risky.
- Upload the file here, or paste it. The email, name, company, website and Wiza status columns are found by name.
- Choose what to set aside: invalid and role addresses (on to start), risky or unverified addresses, personal webmail. Tick the option to read second email columns as well.
- Download the clean list and the set-aside file, each with a flags column.
Example
- You enter
- A Wiza download with 6 rows and an
email_statuscolumn: 3 valid (one of theminfo@), 1 risky, 1 unfound and a repeat of the first address in different case. - You get
- 3 in the list (the risky one marked, the off-domain lead flagged),
info@set aside as a role address, the repeat merged and 1 row counted as having no email. - Limits
- Reads the vendor's own status; it is not a mailbox check today. Runs in your browser with no row cap; an uploaded file can be up to 25 MB.
What does Wiza's risky status mean for a campaign?
Wiza's help centre says a risky address is one it found but could not fully verify, and suggests leaving risky addresses out or mixing in only a small share. They are kept here and marked risky so you can decide; tick the option to set them aside.
Valid is also a snapshot from the day Wiza checked, and people change jobs. A live mailbox check shows which addresses exist today and which domains accept everything.
Which Wiza download should I use?
Wiza lets you download Valid, Risky or All. Downloading All and sorting here keeps the risky rows in a separate file you can check later instead of losing them. The set-aside file lists the reason for every row.
What else does it flag?
Role addresses such as info@ and sales@ are set aside by default, because they reach a shared inbox rather than a person. Personal webmail (Gmail, Yahoo, Outlook.com) on a B2B list and likely domain typos such as gmial.com are flagged, and so is an address on a different domain from the company website: often a parent company, an old domain or a guessed pattern.
Repeated addresses are merged and the weakest status on any copy wins. Rows with no address are counted, not dropped silently. Everything runs in your browser; the file is never uploaded.
Who uses this tool, and for what?
- Cold emailers
- Split a Wiza download into the valid rows to send and the risky rows to check, before it goes into a sequencer.
- Agencies
- Hand a client a Wiza list with role addresses and repeats already removed, and a set-aside file that shows why.
- Recruiters
- Check a LinkedIn-sourced list for personal webmail before a first message.
What can’t this tool tell you?
- Wiza doesn't publish every column name of its export; the email, status and name columns are found by name from an inferred list, so check the notes above the result.
- It can't tell which addresses have a working inbox today, or which domains accept every address; that needs a live mailbox check.
- A purchased or enriched list is cold: nobody on it asked to hear from you. Follow the rules where your recipients are.
Common questions
- Does it re-verify the addresses?
- No. It reads the email_status Wiza wrote into the file. A status from weeks ago can be out of date; /verify checks each mailbox now.
- What if the export has no email_status column?
- Then every address is shown as unchecked and the notes above the result say so.
- Are unfound rows removed?
- Rows with no email address are counted and left out of the list, since there is nothing to send to.
- Can I paste instead of uploading?
- Yes. Pasted CSV text works the same as a file, and .xlsx files are read too.
- Is my lead list uploaded?
- No. The file is read in your browser and nothing is sent anywhere unless you choose to check the addresses afterwards.
Sources
A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
