How to Clean a Snov.io Prospect Export Before Sending

Export the prospect list from Snov.io with the email status field ticked, set aside not-valid and role addresses, keep unknown (yellow) addresses in a separate risky file, leave Email 2 out unless you need it, and check the clean file live before the first send. The colour labels do most of the work, as long as they're in the file.

The Snov.io export to email list tool does the sorting in your browser. Here's the process step by step.

Step 1: Export with the right fields

Snov.io's export article (read 3 November 2026) describes the flow:

1. Open Leads (Prospects), pick the list, then the three-dot menu and Export prospect list.
2. Use the filters at the top to choose which email statuses to include. You can also export only the primary email for prospects with several.
3. Tick the columns you want. Include email, email status, name, company and company URL.
4. Choose CSV, XLSX or Google Sheets.

The article says data export is available on premium plans. It doesn't say outright that the status appears as a column, so tick it explicitly and check the file.

Step 2: Read the colours

Snov.io's credits article sets out what each colour costs in its Finder tools, which tells you how Snov.io itself rates them:

Colour	Meaning	Finder charge	What to do
Green	Valid	1 credit	Keep; re-check if old
Yellow	Unknown	1 credit	Separate risky file
Red	Outdated or deactivated	Free	Set aside
Gray	Not found	Free	Nothing to send to

Yellow is the group to watch. An unknown result usually means the mail server wouldn't give a clear answer: it accepts every address, it greylisted the check, or it timed out. You've paid for it, but it isn't proven. Our post on accept-all vs unknown results explains how to tell those cases apart.

Step 3: Set aside role addresses and repeats

• Role addresses (info@, sales@, support@): shared inboxes with low reply rates and more complaints. The role-based email filter catches them.
• Repeats: the same prospect from two searches or two lists. Merge them so nobody gets two first touches.
• Off-domain addresses: an email on a different domain from the company URL is often a parent company, an old domain or a pattern guess. Check those first.

Step 4: Decide about Email 2

Snov.io sometimes returns a second address. Second addresses tend to be older or personal ones. The tool leaves them out unless you tick the option; then each becomes its own row with a note saying where it came from. If the person's work address is green, there's rarely a reason to add the second one to a cold sequence.

Step 5: Check the clean file live

A green status is true on the day the search ran. Upload the clean file at /verify: every address gets a live mailbox check, valid, risky and invalid download as separate files, and catch-all domains are marked, which separates the yellow addresses that will never resolve from the ones that just didn't answer the first time.

Load only the valid file into the main campaign. Put catch-all addresses in a smaller, slower one or drop them. Our post on catch-all leads in sequences covers how to size that.

Honest limits

• Column names aren't published. Snov.io doesn't document its export headings, and the file only has the fields you tick; the tool finds the status and Email 2 columns by name, so check the notes above the result.
• Unknown stays unknown on catch-all domains. No checker can prove a mailbox on a server that accepts every address.
• A prospect list is cold. Nobody on it asked to hear from you. Follow the rules where your recipients are.

Where SimpleVerifier fits

The export tool is free and runs in your browser. The live check is the paid part: the first 100 checks are free with a Google sign-in on the verify page. Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off, and one-time packs of 10,000 checks for $15 never expire. See pricing.
