Generect vs Go4Database: Which B2B Data Tool Wins?
You exported 1,000 contacts, loaded them into your sequencer, and 250 bounced. Your domain reputation took a hit, open rates cratered, and now you're shopping for a new data provider. That's probably how you ended up comparing Generect vs Go4Database - two tools most teams haven't seen stacked against each other. Neither has a meaningful Reddit presence, which tells you something about adoption among the communities that typically vet B2B tools publicly.
30-Second Verdict
Pick Generect if you want real-time data on every search and prefer pay-per-lead flexibility over a monthly subscription.
Pick Go4Database if you're a solo freelancer on a tight budget who needs a cheap entry point and low volume.

Go4Database has been around since 2012 but didn't launch its "next-generation platform" until October 2024. Twelve years is a long time to modernize - and user feedback suggests the underlying data hasn't fully caught up.
Data Quality
This is the only metric that actually matters for outbound. Bad data doesn't just waste credits - it burns your sending domain.
Generect updates data in real time, pulling fresh information from public sources each time you search. It also verifies contact info instantly when you view a lead, and users report over 98% accuracy with bounce rates under 2%. In our testing, pay-per-lead models like this tend to keep teams more disciplined about list quality because you think twice before exporting when every contact costs $0.05.
Go4Database guarantees 95% accuracy and offers replacements within 24 hours if you prove the data fell below that threshold. In practice, one reviewer reported roughly 25% of emails bounced in a test sequence - a massive gap between promise and reality. The platform compiles data from public sources, tele surveys, business directories, affiliate networks, and job portals. That patchwork approach helps explain why bounce-rate complaints show up in reviews. On Trustpilot, it holds a 4.0 rating from just 4 reviews, with praise centered on responsive support rather than data quality.
Here's the thing: a 25% bounce rate isn't just annoying. It's a domain-reputation emergency. Anything above 5% risks blacklisting with major email providers, and recovering from that takes weeks of warmup and throttled sending. We've watched teams lose months of pipeline momentum over exactly this kind of data quality gap. If you want a deeper breakdown of bounce thresholds and what they mean, see our guide on email bounce rate.
A 25% bounce rate destroys your domain. A 5% bounce rate still hurts. Prospeo's 5-step verification - with catch-all handling, spam-trap removal, and honeypot filtering - delivers 98% email accuracy across 143M+ verified addresses. That's why teams like Meritt cut bounce rates from 35% to under 4% after switching.
Stop gambling your sender reputation on unverified data.
Pricing Breakdown
| 1,000 leads | 5,000 leads | |
|---|---|---|
| Generect | $50 (1,000 x $0.05) | $250 (5,000 x $0.05) |
| Go4Database | $35/mo (Nano: 1,500 contacts) | Custom pricing required |
Generect charges $0.03 per valid email found plus $0.02 per export. No subscription, no commitment - you top up a wallet (minimum $20) and go. For teams with unpredictable volume, that flexibility matters. If you're comparing more pay-per-lead tools, you can also look at Bytemine vs Generect.
Go4Database runs a traditional subscription. The Nano plan at $35/month gets you 1,500 contacts. The Micro plan at $59/month bumps that to 3,000 across two users. There's also a free trial tier with 100 contacts per month if you want to test before paying. One detail that raised our eyebrows: Go4Database accepts Bitcoin and USDT as payment methods and charges a 50% cancellation fee on undelivered orders. Make of that what you will.
Who Should Pick Which
Go4Database works for solo freelancers or beginners running low-volume outreach who are comfortable with replacement-only guarantees and a CSV-based workflow. If you're still building your outbound motion, these sales prospecting techniques can help you get more from smaller lists.
Generect fits outbound teams that want real-time data without subscription lock-in, are willing to pay per lead for freshness, and already use CRMs that can connect via API. If you're evaluating systems to manage those leads, start with our roundup of contact management software.
Let's be honest about the gaps, though. Neither tool fits if you're running high-volume cold outreach where bounces kill domain reputation, need native integrations with sequencers like Instantly or Lemlist, or are scaling past a few thousand leads per month while watching cost-per-lead closely. For a more complete playbook on sequencing, see our B2B cold email sequence guide.
A Third Option Worth Testing
Both tools in this comparison solve pieces of the problem, but neither delivers the full package. We've seen teams switch from static databases and cut bounce rates from 35% to under 4% while tripling connect rates - Meritt, for example, went from $100K to $300K/week in pipeline after making that switch. When your domain reputation is on the line, the gap between 95% and 98% accuracy isn't academic. It's the difference between landing in inboxes and landing in spam. If you're actively trying to protect deliverability, our guide on how to improve sender reputation is a good next read.
Prospeo pairs a 7-day data refresh cycle with 30+ search filters for buyer intent, job changes, technographics, and funding signals so you're targeting accounts actually in-market. Its 300M+ professional profiles and 143M+ verified emails outsize both competitors' databases, and the proprietary 5-step verification process - including catch-all handling, spam-trap removal, and honeypot filtering - explains why accuracy stays at 98%. Native integrations with Salesforce, HubSpot, Instantly, Lemlist, Smartlead, Clay, and Zapier mean you don't have to rely on CSV exports. If you're benchmarking vendors in this category, see our list of the best sales prospecting databases. The free tier gives you 75 verified emails per month plus 100 Chrome extension credits to test before committing, and paid plans run roughly $0.01 per email with no contracts.
At 5,000 leads/month, Generect costs $250 and Go4Database needs custom pricing. Prospeo handles the same volume for ~$50 with 98% accuracy, a 7-day data refresh, and native integrations with Instantly, Lemlist, Smartlead, and HubSpot - no CSV exports required.
Pay $0.01 per email instead of $0.05. Start free, no contract.
FAQ
Is Go4Database accurate enough for cold email?
Go4Database guarantees 95% accuracy, but at least one third-party reviewer reported roughly 25% bounced emails in a test sequence. For low-volume outreach that's tolerable. For serious cold email campaigns where domain reputation matters, that bounce rate is dangerous - anything above 5% risks blacklisting.
Does Generect integrate with CRMs?
Generect offers API access and CRM syncing, which puts it well ahead of Go4Database's CSV-based workflow. Check their integrations page before committing to confirm your specific stack is covered - not all CRMs are supported natively.
Which tool is cheapest at scale?
At 5,000 leads per month, Generect runs roughly $250/month. Go4Database's published tiers top out at 3,000/month on Micro, so 5,000/month requires custom pricing. Prospeo handles the same volume for approximately $50/month with 98% accuracy - making it the most cost-effective option when you factor in bounce-related costs like damaged sender reputation.
What's a good free alternative to both?
Prospeo's free tier includes 75 verified emails and 100 Chrome extension credits per month - enough to test real campaigns. Go4Database offers 100 contacts/month free, and Generect has no free tier (minimum $20 wallet top-up). For teams validating a new data source before committing budget, the free plan with full verification included is the safest starting point.
