Prospeo export to email list: catch-all marked, invalid set aside
In short: Reads a Prospeo CSV or XLSX export, reads the email status (valid, catch-all, invalid), sets aside invalid and role addresses, marks catch-all as risky, merges repeats and flags webmail and typos. Limit: Prospeo doesn't publish the full column list of its export; the email, status and name columns are found by name, so check the notes above the result.
Export your contacts from Prospeo as CSV or Excel with the email status included and upload the file here. Invalid and role addresses are set aside, catch-all addresses are marked risky, repeats are merged and addresses on a different domain from the company website are flagged. Then check the clean file live before the first send.

How do I check the Prospeo 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 Prospeo export before sending?
- In Prospeo, select the contacts in your search or list and click Export. Choose CSV or Excel; Prospeo lets you export only verified emails, only mobiles or all contacts.
- Upload the file here, or paste it. The email, name, company, website and Prospeo 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 Prospeo export with 6 rows and an
email_statuscolumn: valid, catch-all and invalid, ahello@address, one lead on a domain other than the company website and one with no email. - You get
- 3 in the list (catch-all marked risky, the off-domain lead flagged);
hello@and the invalid lead set aside; 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.
Why is catch-all marked risky?
A catch-all domain accepts mail for any address, so a status check can't prove a particular mailbox exists. Those addresses are kept and marked risky; tick the option to set them aside, or send them slowly and in small batches.
A live mailbox check separates domains that accept everything from ones that simply didn't answer the first time.
Should I export only verified emails from Prospeo?
Prospeo's export screen lets you limit the file to verified emails. Exporting everything and sorting here is the other route: you keep a set-aside file with a reason per row instead of never seeing the rest. Either way, a verified status is from the day of the check.
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?
- SDRs
- Remove invalid and shared-inbox addresses from a Prospeo search export before it goes into a sequence.
- Agencies
- Show a client which rows are verified, which are catch-all and why each excluded row was set aside.
- Founders
- Check a bought-credits list is worth sending before it touches a new sending domain.
What can’t this tool tell you?
- Prospeo doesn't publish the full column list of its export; the email, status and name columns are found by name, 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 Prospeo wrote into the export. A status from weeks ago can be out of date; /verify checks each mailbox now.
- Which status words are read?
- Valid is verified, catch-all is risky and invalid is set aside; other words are shown as written and treated as unchecked.
- Does it work on files from the CSV enrichment feature?
- Yes, as long as the file has an email column. The enrichment output and the search export are read the same way.
- Can I upload an Excel file?
- Yes. CSV, XLSX and pasted text all work.
- 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
