CSVgo vs SMARTe: They Don't Actually Compete
Comparing CSVgo and SMARTe is like comparing a spell-checker to a word processor. One cleans what you already have; the other builds something from scratch. B2B contact data decays by roughly 30% every year, so every team needs both sourcing and verification - but these two tools only handle one side each.
That's the core tension. Let's break it down.
30-Second Verdict
- Use CSVgo if you already have a lead list and need to clean, verify, and segment it before launching sequences.
- Use SMARTe if you're starting from zero and need to build a contact list with emails and direct dials.

Quick Feature Comparison
| CSVgo | SMARTe | |
|---|---|---|
| Primary function | Email verification + list cleanup | Contact database + enrichment |
| Database size | None (verifies your data) | 290M+ contacts, 65M+ companies |
| Pricing | ~$20-$100/mo (estimated) | Free; Pro $25/mo; Enterprise $0.20-$0.30/credit |
| Best for | Cold emailers cleaning exports | Teams sourcing new prospects |
| G2 rating | Not listed | 4.6/5 (24 reviews) |
| Integrations | API access | Salesforce, HubSpot, Outreach, Salesloft, Microsoft Dynamics |
| Compliance | - | SOC 2 Type II, GDPR aligned, CCPA compliant |

Why pay for SMARTe and CSVgo separately when one platform does both? Prospeo's 300M+ profiles come pre-verified at 98% accuracy with built-in catch-all handling - no export-clean-reimport loop required.
Kill the two-tool tax. Find and verify in one workflow.
What Each Tool Actually Does
CSVgo
Use this if you're exporting leads from another tool and need one workflow to clean, verify, and segment before sending. A practitioner on r/coldemail who's booked 1,000+ B2B calls described CSVgo as replacing four separate tools - handling cleanup, verification, catch-all validation, and ESP detection in a single pass. They reported finding roughly 30% more usable leads than standard verifiers, largely because of the catch-all handling. That's a meaningful edge if you're running high-volume outbound and every deliverable address counts.
Here's the thing: CSVgo has no database. Zero. It's purely a verification layer. If you need to source contacts in the first place, you're looking at the wrong tool. Pricing isn't publicly listed, but comparable verifiers run $20-$100/mo or roughly $0.0005-$0.003 per email at scale. We couldn't find G2 or Capterra reviews during our research, so that Reddit thread is the best public signal available.
SMARTe
SMARTe takes the opposite approach entirely - it's a contact database, not a verifier. The 290M+ contacts across 65M+ companies and 200+ countries give it solid global reach, with 75% US and 50% global direct-dial coverage. Pricing tiers are refreshingly transparent. The free plan gets 10 credits/month, Pro runs $25/mo at $0.50/credit, and Enterprise drops from $0.30 down to $0.20/credit at higher volumes. SOC 2 Type II certified, GDPR and CCPA compliant.
The catch: G2 reviewers flag inconsistent data for smaller or niche accounts and occasional CRM sync duplicates. Signals and AI Agents are Enterprise-only features, so Pro users don't get them. The free tier's 10 credits is barely enough to evaluate the product - you'll burn through those in minutes. And while SMARTe reports 86% verified email reach for U.S. decision-makers, that's a database-level stat, not the same as running each address through real-time verification before you hit send.
Which One Do You Actually Need?
These tools serve different moments in your workflow.

You exported leads and need to clean before sending? CSVgo handles verification, catch-all validation, and ESP segmentation in one pass. Starting from zero and need to source contacts? SMARTe gives you a searchable database with direct dials and emails. Sourcing from SMARTe and verifying with CSVgo? It works, but that's two subscriptions and two workflows for what should be a single step.
Here's our hot take: if your average deal size sits below five figures, you probably can't justify paying for both a database and a separate verifier. The friction alone kills follow-through. We've watched teams buy both tools and still send unverified emails because the export-clean-reimport loop is too tedious to maintain week after week.
One Tool That Does Both
Prospeo eliminates the two-tool problem. Its database covers 300M+ professional profiles with 98% email accuracy, and every record refreshes on a 7-day cycle - not the 6-week industry average. Built-in 5-step verification includes catch-all handling, spam-trap removal, and honeypot filtering, so there's no separate cleaning step before you launch sequences.

The free tier gives you 75 verified emails and 100 Chrome extension credits per month. No contracts, no sales calls required. For teams currently paying for both a database and a verifier, that's real money back and one less integration to babysit.
If you want a broader view of data enrichment options, or you're comparing sales prospecting databases, it helps to map tools to the exact stage they support.


CSVgo cleans lists. SMARTe builds them. Prospeo does both - with a 7-day data refresh cycle, 5-step verification, and 75 free verified emails per month. No sales call, no annual contract.
One platform, zero duct-tape integrations. Start in 60 seconds.
FAQ
Can I use CSVgo and SMARTe together?
Yes. Source contacts in SMARTe, then run the list through CSVgo for verification and catch-all handling. It works, but you're managing two subscriptions and two export-import steps for what could be a single workflow.
Does SMARTe verify emails before exporting?
SMARTe reports 86% verified email reach for U.S. decision-makers, but it's a database-first tool. Running exports through a dedicated verifier before sending is still best practice to keep bounce rates under 5%.
