Go4Database vs OneMoreLead: Which B2B Data Tool Should You Actually Use?
We sell Prospeo. You're reading our blog. So let's get the bias out of the way up front: if you're weighing Go4Database vs OneMoreLead, the honest answer is that neither tool inspires much confidence - and you deserve to know why before spending a dollar.
30-Second Verdict
Go4Database is cheap but ships data that bounces at roughly 25%, based on a G2 reviewer who documented it in a live sequence test. That's nearly double the widely cited industry benchmark of 5-15%. OneMoreLead has effectively zero third-party reviews on major platforms and suffered a 126-million-record data breach that exposed 34GB of PII. Skip both.
Head-to-Head Comparison
| Criteria | Go4Database | OneMoreLead | Winner |
|---|---|---|---|
| Starting price | $35/mo billed annually | $99/mo (Freelancer) | Go4Database |
| Cost per contact | ~$0.023/contact (Nano annual) | $0.20-$0.40/contact | Go4Database |
| Effective cost* | ~$0.03/contact | Unknown - no accuracy data | Go4Database (barely) |
| Database size | Not independently verified | 55M+ (inconsistent claims) | Neither |
| Email accuracy | ~75% (user report) | Unknown | Go4Database (by default) |
| Data refresh | Unknown | Unknown | Neither |
| G2 rating | 4.8/5 (5 reviews) | No meaningful review footprint | Go4Database |
| Data incidents | None reported | 126M records exposed | Go4Database |
| GDPR compliance | Unclear | Questionable | Neither |
*Effective cost adjusts for bounce rate - you're paying for contacts that actually work.
Go4Database wins every measurable row, but winning against a tool with a catastrophic breach and zero reviews is a low bar.
Go4Database bounces 1 in 4 emails. OneMoreLead leaked 126M records. You don't have to choose between bad data and dangerous data - Prospeo delivers 98% verified emails across 300M+ profiles at ~$0.01 each, with a 7-day refresh cycle.
Stop paying for contacts that wreck your domain reputation.
Tool Profiles
Go4Database
Use this if you need the cheapest possible lead lists and you're willing to verify everything yourself before sending. The Nano plan at $35/mo billed annually gives you 1,500 contacts monthly, and the free trial includes 100 contacts/month with all filters. Customer support gets consistent praise on both G2 (4.8/5, 5 reviews) and Trustpilot (4.0/5, 4 reviews).
Skip this if you're running cold email at any real volume. That ~25% bounce rate from a reviewer's sequence test is a domain reputation killer. One in four emails bouncing will get you flagged by ESPs fast, and recovering sender reputation takes weeks of warm-up that most teams can't afford.
Go4Database's Trustpilot profile says they've been in business for 14+ years with 60,000 customers across 200+ countries, but only 9 total reviews across G2 and Trustpilot back that up. The BBB gives them an A- (not accredited), and the file was opened in December 2024. For a company positioning itself as long-established, that's a thin paper trail.
There's also a confusing pricing discrepancy on G2: Nano shows $35 plus "$55 (Monthly)" in the same listing, and Micro shows $59 plus "$95 (Monthly)." Likely annual vs. monthly billing without clear labels, but confirm directly with Go4Database before purchasing.
OneMoreLead
We can't recommend a scenario where this is the right call.
Pricing starts at $99/mo for just 250 credits - that's $0.40/contact. The $399/mo Business plan drops that to $0.20/contact but still only gives you 2,000 credits. For comparison, Prospeo's credit-based pricing works out to roughly $0.01/email with 98% accuracy, which makes OneMoreLead's cost-per-contact look absurd even before you factor in the trust issues.
The real problem is trust. OneMoreLead leaked up to 126 million U.S. citizens' records through a misconfigured ElasticSearch server - 34GB of PII including home addresses, phone numbers, emails, IP addresses, and government/police records. As Woodpecker noted, there are literally no reviews online for OneMoreLead.
Their homepage can't agree on its own numbers: "55M+ Pure Leads" in one section, "more than 40 million candidates" in another, and "170M Employees" elsewhere. That kind of inconsistency, combined with zero social proof and a massive breach, is disqualifying.
Trust and Data Quality
Both tools fail basic due diligence checks that any RevOps team should run before signing a vendor.
Go4Database's 25% bounce rate isn't just an inconvenience - it's actively dangerous to your sender reputation. Bouncing one in four emails means you're burning through domain trust with every campaign. Cheap data that wrecks deliverability costs more in the long run than accurate data at a higher sticker price. And in the Reddit threads we've reviewed, neither tool showed up in discussion at all, which is another signal of thin community adoption.
Here's the thing: if your sales intelligence budget is tight enough that either of these platforms looks attractive, you're better off using a free tier from a tool with verified accuracy than paying for a contact database full of dead emails. Bad data doesn't just waste money. It actively damages your ability to reach anyone.
For context, Prospeo covers 300M+ professional profiles with 98% email verification accuracy at ~$0.01/email. Data refreshes every 7 days - compared to the 6-week industry average. The free tier gives you 75 verified emails per month, enough to run your own accuracy test before committing a cent. Snyk's 50-person sales team cut bounce rates from 35-40% to under 5% after switching, and their AE-sourced pipeline jumped 180%.
If you want to sanity-check list quality before you send, use an email bounce rate benchmark and a basic email deliverability checklist.
Snyk's 50-person sales team cut bounce rates from 35% to under 5% with Prospeo - and grew AE-sourced pipeline 180%. No contracts, no annual lock-in. Start with 75 free emails and run your own accuracy test against either tool.
Let your bounce rates decide which platform wins.
Final Verdict
Skip both. In the Go4Database vs OneMoreLead matchup, neither tool gives you the confidence to run outbound at scale. Go4Database is affordable but ships data that'll wreck your deliverability. OneMoreLead has a catastrophic breach on its record and zero third-party validation.
If your budget is larger, Apollo and ZoomInfo are established options - though both cost significantly more per verified contact. Prospeo sits between them on price while delivering 98% email accuracy and weekly data refreshes, making it the strongest starting point for teams that can't afford bad data.
Start with a free tier, run your own accuracy test, and let the bounce rates speak for themselves.
FAQ
Is OneMoreLead safe after its data breach?
The breach exposed 126M records of PII via a misconfigured ElasticSearch server, and no public remediation details exist. Request a current SOC 2 report and independent penetration test results before considering them - without those, the security risk is impossible to quantify.
Why does Go4Database show different prices on G2?
The G2 pricing page displays two figures per tier (e.g., Nano shows $35 and "$55 Monthly"). This likely reflects annual vs. monthly billing without clear labels. Confirm exact billing terms directly with Go4Database before purchasing.
What's a reliable alternative to both tools?
Prospeo offers 98% email accuracy across 300M+ profiles at ~$0.01/email, with a free tier of 75 verified emails per month and a 7-day data refresh cycle. For teams that need dependable B2B contact data without the trust concerns these two carry, it's the strongest option to test first.
