Datanyze vs Go4Database: Different Tools for Different Workflows
These two tools get compared because they both sell B2B contact data. That's about where the similarity ends. When you weigh Datanyze against Go4Database, you're really comparing a Chrome extension that reveals contacts while you browse - prospecting with technographic context baked in - against a bulk list provider that delivers CSV/XLS files by industry. It's a scalpel versus a shovel.
30-Second Verdict
If you prospect in-browser and want contacts revealed on company websites with tech-stack context, Datanyze is the better fit. It's lightweight and credit-based. (If you're tightening your workflow, see sales prospecting techniques that pair well with in-browser tools.)
If you need pre-built industry lists at a low price and don't care about on-page lookup, Go4Database delivers volume for less money. You're buying a mailing list, not a prospecting tool. If you're evaluating vendors in this category, compare options in our guide to email list providers.
Side-by-Side Comparison
| Feature | Datanyze | Go4Database | Edge |
|---|---|---|---|
| Database size | 120M contacts | 400M claimed | Go4Database (on paper) |
| Pricing | $29/mo (80 credits) or $55/mo (160 credits) | $35/user/mo annual / $55/user/mo monthly (1,500 contacts/mo) | Go4Database |
| Free plan/trial | 10 credits/mo for 90 days | 100 contacts/mo (1,200/year) | Go4Database |
| Delivery model | Chrome extension | CSV/XLS download | Datanyze |
| Chrome extension | Yes | No | Datanyze |
| API | No public API | No | Neither |
| CRM integrations | Salesforce, HubSpot | Complimentary 2-year CRM license | Datanyze |
| G2 rating | 4.1/5 (446 reviews) | 4.8/5 (5 reviews) | Datanyze (more signal) |
| Accuracy guarantee | None published | 95% claim + replacement guarantee | Neither proven |
Go4Database claims 400M contacts at a fraction of Datanyze's per-contact cost. But there's no extension, no API, and no native CRM sync - you're downloading spreadsheets. Datanyze gives you fewer contacts but embeds them into your actual prospecting workflow with technographic intelligence. If you're comparing broader options, start with sales prospecting databases.
Datanyze wastes credits on stale contacts. Go4Database gives you unverified CSVs with reported 25% bounce rates. Prospeo runs 5-step verification on every record - including catch-all handling and spam-trap removal - before you spend a single credit. 98% email accuracy, 7-day data refresh, and 300M+ profiles with 30+ filters.
Stop choosing between a scalpel and a shovel. Get both precision and scale.
When to Pick Each Tool
Datanyze
Pick it if you prospect from company websites and want contacts revealed in-browser, if technographic data matters to your sales motion, or if you need Salesforce/HubSpot integration out of the box. Companies using technographic data in their outreach see roughly a 20% lift in conversion rates, so that context isn't trivial. Reddit users have called Datanyze "the best bang for the buck" for small-volume prospecting at $29 for 80 reveals. (If you're building a repeatable outbound motion, use these sales activities examples to structure it.)
Skip it if you need responsive support. Users report sending 20-30 emails before getting a reply. That's not a minor gripe - it's a pattern across multiple G2 reviews. Also not ideal if you prospect heavily outside North America.
Go4Database
Pick it if you want bulk industry lists at a budget price. 1,500 contacts per month for $35/user/month on annual billing is hard to beat on raw volume. The complimentary two-year CRM license sweetens the deal for startups with no existing CRM (see examples of a CRM if you're choosing one), and they accept Bitcoin and USDT, which is unusual for a B2B data provider.
Skip it if you expect refunds for bad data. Go4Database has a no-refund policy with a 50% cancellation charge on undelivered orders. If bounce rates above 10% would damage your sender reputation, that's a real risk to weigh before committing. If deliverability is a priority, review email reputation tools and an email deliverability guide.
Data Quality: The Part That Actually Matters
Here's the thing: 22.5-30% of B2B contact data decays every year. People change jobs, companies get acquired, emails go dead. Any static database rots fast. If you're trying to keep records current, consider data enrichment services.
Go4Database claims 95% accuracy, but one reviewer reported a ~25% email bounce rate. With only 5 reviews on G2 and 4 on Trustpilot, there isn't enough signal to validate that claim. All 5 G2 reviewers are from Asia. The company lists a US PO Box while the founder is based in Noida, India - none of which is disqualifying, but it's worth knowing.
Datanyze has a deeper review footprint at 446 reviews, and the pattern is clear: users love the Chrome extension but consistently flag outdated contacts and credits wasted on stale data. We've seen this firsthand in our own testing - credits that evaporate on records that bounce aren't really credits at all. If you're troubleshooting list performance, use these benchmarks and fixes for email bounce rate.
Let's be honest: a 4.8 rating from 5 reviews tells you almost nothing. A 4.1 from 446 reviews tells you a lot, including that roughly 13% of users had a genuinely bad experience.
If you're selling deals under $5K, neither tool's data quality justifies the time you'll spend cleaning bounced emails. You need verified data from the start, not a cheaper firehose of maybes.
A Better Third Option
For context, Meritt went from $100K to $300K/week in pipeline after switching, while cutting bounce rates from 35%+ to under 4%. That's the difference between verified-first data and "download and pray." If you're building a cleaner pipeline system, track the right pipeline health metrics.
Meritt cut bounce rates from 35% to under 4% and tripled pipeline to $300K/week after switching to Prospeo. No CSV downloads, no wasted credits on dead emails - just verified contacts with native Salesforce and HubSpot integrations, a Chrome extension used by 40,000+ prospectors, and data refreshed every 7 days instead of the 6-week industry average.

Does Datanyze have a free plan?
Yes. Nyze Lite gives 10 credits per month for 90 days with a business email. Paid plans start at $29/month for 80 credits or $55/month for 160 credits. Go4Database offers 100 free contacts per month - more volume, but unverified CSV downloads.
Is Go4Database GDPR compliant?
Go4Database claims GDPR and CAN-SPAM compliance. Their data comes from tele surveys, website business directories, and affiliate networks - sourcing methods worth scrutinizing before running EU campaigns. If you're targeting European prospects, verify their data processing agreements before committing.
Which tool has better verified emails?
Neither excels here. Datanyze doesn't publish an accuracy guarantee, and credits aren't refunded for unusable records. Go4Database's user-reported bounce rates contradict their 95% claim. Teams needing sub-5% bounce rates typically move to verification-first platforms that run multi-step verification - including catch-all handling and spam-trap removal - on every record before delivery.
