CSVgo vs Wiza: You're Comparing the Wrong Tools
You're looking at CSVgo vs Wiza like they're competitors. They're not. One verifies emails you already have. The other finds emails you don't. Comparing them is like comparing a proofreader to a researcher - related skills, completely different jobs.
We've seen teams waste months stitching these two together when a single platform handles both. Here's how to figure out which one you actually need.
30-Second Verdict
- Already have a list and need to clean it before sending? CSVgo.
- Need to build a list from scratch - say, 500 VPs of Marketing at SaaS companies? Wiza.
- Need both finding and verification? Skip both and use Prospeo, which handles the entire workflow at ~$0.01 per email.

What Is CSVgo?
CSVgo is a single-purpose email verification tool for cold emailers who already have a list. Its standout feature is catch-all verification - meaningful given that roughly 30% of B2B domains use catch-all configurations, which means most verifiers just shrug and mark those addresses "unknown."
CSVgo positions this as a speed advantage: most verifiers take 30-45 minutes per batch, while CSVgo processes thousands of rows in minutes. The company also claims it recovers 20-30% more usable leads through its catch-all handling, and it groups contacts by ESP (Gmail, Outlook, SMTP) so you can segment for deliverability before you hit send.
Use this if: You're running cold email at volume and need fast list cleaning. One Reddit user in r/Entrepreneur said CSVgo "replaced four other tools" in their stack.
Skip this if: You need to find contacts. CSVgo has no database - you bring your own list, period.
CSVgo verifies. Wiza finds. Prospeo does both - 300M+ profiles with 98% email accuracy and catch-all handling built in. At ~$0.01/email, you replace two subscriptions, two dashboards, and two billing cycles with one workflow.
Stop stitching tools together. Get finding + verification in one step.
What Is Wiza?
Wiza is a prospecting tool built around LinkedIn Sales Navigator. You search for prospects in Sales Nav, and Wiza's Chrome extension exports them with emails, phone numbers, and 40+ data points. The database covers 850M+ prospects.
Wiza markets 99%+ deliverability, though real-world accuracy lands closer to 90-95% for emails and 55-65% for phones. That gap matters when you're paying per credit.
What users love: 4.5/5 on G2 from over 1,100 reviews. Ease of use is the top strength (427 mentions), and built-in verification means you pay only for valid contacts.
What users hate: "Expensive" is the #1 G2 complaint (157 mentions), followed by "limited credits" (127 mentions) and "inaccurate data" (57 mentions). Coverage outside North America is weaker, especially in LATAM. Annual subscribers report sudden API access changes without notice. And the "Unlimited" annual plan? Users say it has hidden caps around 10,000 monthly credits. Let's be honest - that's not unlimited.
Pricing Breakdown
| Plan | Wiza | CSVgo |
|---|---|---|
| Free | $0 (20 emails/mo, 5 phones/mo) | - |
| Entry | $49/user/mo (100 emails, 100 phones) | ~$0.007-$0.01/email |
| Mid | $99/user/mo (500 emails) | Volume discounts likely |
| Team | $449/mo (3+ users) | - |
| Hidden costs | Sales Navigator: $99-149/mo | None known |
Here's the thing about Wiza's pricing: the Email + Phone plan at $199/user/mo only makes sense with Sales Navigator, which adds $99-149/mo. That's $265-315/mo for a single seat before overages. Extra emails cost $0.15 each, extra phones $0.35 each. Those overages add up fast if you're prospecting at any real scale.
If your average deal size is under $10k, Wiza's all-in cost probably eats your margin. CSVgo is dramatically cheaper, but you're comparing a verification-only tool to a full prospecting platform - they don't substitute for each other.
Which One Do You Need?
Three scenarios, three answers.
You have a list and need to clean it. CSVgo. A bounce rate above 5% triggers spam filtering, and once your domain reputation tanks, recovery takes 6-12 weeks. We've watched teams lose entire sending domains over this. Don't be that team.
You need to build a list from scratch. Wiza works well for pulling verified contacts out of Sales Navigator searches, especially if your ICP is North America-heavy. For teams targeting EMEA or APAC, expect thinner coverage.
You need both finding and verification. This is where paying for two separate tools stops making sense. Prospeo combines 300M+ profiles, 98% email accuracy, and a 5-step verification process that handles catch-all domains - with data refreshed every 7 days instead of the 6-week industry average. In our testing, the catch-all handling alone flagged 20-30% more usable addresses than standard verifiers. The free tier gives you 75 emails per month, paid plans run ~$0.01 per lead, and there's no Sales Navigator dependency baked into the workflow.
Wiza needs Sales Navigator at $99-149/mo to work properly. Prospeo doesn't. You get 300M+ profiles, 125M+ verified mobiles, and data refreshed every 7 days - no LinkedIn dependency, no hidden caps, no annual contracts.
Drop the $300/mo stack. Get better data for a penny per lead.
FAQ
Can I use CSVgo and Wiza together?
Yes. Use Wiza to find contacts from LinkedIn, then run the exported list through CSVgo for a second verification pass. It works, but you're managing two subscriptions, two dashboards, and two billing cycles for something a combined platform handles natively.
Does Wiza work without Sales Navigator?
Technically yes, but filters and export volume are severely limited. Most serious users pair it with Sales Nav at $99-149/mo, pushing the true monthly cost to $265-315 for the Email + Phone plan. Wiza's own pricing page doesn't make this dependency obvious.
How much does CSVgo cost?
CSVgo doesn't publish pricing publicly. Based on industry benchmarks for email verification, expect $0.007-$0.01 per email. You'll need to sign up or contact their team for exact numbers.
What's a good alternative if I need both finding and verification?
Prospeo covers both in a single platform - 300M+ profiles, 98% email accuracy, catch-all handling, and 125M+ verified mobile numbers. At ~$0.01 per lead with a free 75-email monthly tier, it replaces the CSVgo-plus-Wiza stack at a fraction of the combined cost.
