Go4Database vs ReachFast: Which B2B Data Provider Is Worth Your Money?
Two B2B data tools, both starting around $35/month, both claiming 350M+ contacts - and with just 17 G2 reviews between them. Choosing between Go4Database and ReachFast feels like picking between two restaurants with barely any Yelp reviews. Here's what the data actually says.
30-Second Verdict
- Go4Database - Best for bulk email lists on a tight budget ($0.023/contact, 18K contacts/year).
- ReachFast - Best for direct-dial phone numbers (mobile-first, 92%+ direct dial accuracy claimed).
Why This Comparison Is Tricky
Between Go4Database and ReachFast, there are exactly 17 G2 reviews. That's not a dataset - it's a dinner party. Go4Database claims 60,000+ customers but has just 5 reviews. ReachFast has 12. Neither tool has meaningful Reddit discussion or independent benchmarks.
That matters because B2B contact data decays at roughly 2.1% per month - about 22.5% annually. Without independent validation, you're trusting vendor numbers that were true once but aren't necessarily true for your target list today.
Feature-by-Feature Breakdown
| Feature | Go4Database | ReachFast |
|---|---|---|
| Database size | 350M contacts | 385M+ professionals |
| Email accuracy | 95-100% (claimed) | 97%+ (claimed) |
| Entry price | $35/mo (Nano) | $35.30/mo (H-beta) |

Database size numbers look similar. But size without accuracy is just noise.
Go4Database - What You Get
Use this if you need high-volume email lists at rock-bottom cost and can tolerate data cleanup. The Nano plan at $35/month gets you 18,000 contacts per year as downloadable CSV/Excel files - that's $0.023 per contact, genuinely cheap. Advanced filtering by job role, industry, and location works well for bulk campaign targeting (and pairs well with a tighter lead generation workflow so you don’t waste credits).
Skip this if you can't afford bounces. One reviewer reported a ~25% bounce rate in their email sequences, turning that $0.023/contact into roughly $0.031 when you adjust for invalid records. We've seen bounce rates like this destroy sender reputation in under a week, and recovery takes much longer than the damage itself. If your domain is new or you're running outbound for clients, that risk isn't worth the savings (see Email Bounce Rate benchmarks and fixes).
Here's the thing: with 14+ years in business, Go4Database's interface feels like it hasn't been updated since 2015. The data might work for high-volume, low-stakes campaigns, but the product experience is firmly stuck in the past.
Go4Database users report 25% bounce rates. ReachFast delivers incomplete records. Prospeo's 5-step verification and 7-day data refresh deliver 98% email accuracy - Snyk's 50 AEs dropped bounces from 35% to under 5%.
Stop guessing which contacts are real. Verify before you send.
ReachFast - What You Get
ReachFast takes a fundamentally different approach. Instead of bulk email lists, it's built around mobile-first direct dials - claiming 92%+ direct dial accuracy with explicit filtering of generic office numbers.
Across G2, Trustpilot, and Software Advice, the tool holds a consistent 4.5/5 rating across 45 total reviews. Trustpilot reviewers often compare ReachFast favorably to tools like Apollo and ZoomInfo, and the tool is particularly strong for Indian market contacts, which is a genuine differentiator if that's your territory.
The downsides are real, though. Multiple reviewers flag duplicates, incomplete records, and slow processing. Several mention getting "half information" - a phone number but no email, or vice versa. The free trial gives you just 5 contacts, which isn't enough to evaluate quality for your ICP (use an Ideal Customer Profile checklist to test the right segment). Pricing starts at $35.30/month, scaling to $99+/month for higher volumes.
Take vendor-authored benchmarks with appropriate skepticism. ReachFast's own homepage claims competitors like ZoomInfo only hit 70-80% email accuracy - but that framing conveniently positions their own 97% claim as gospel. It's marketing, not methodology.
Why Accuracy Claims Don't Hold Up
Both tools make bold accuracy claims. Neither publishes independent verification.
A Salesfinity benchmark testing 307 contacts across 9 providers-accuracy-coverage-real-results) found accuracy ranged from 63% to 91% and coverage from 26% to 92%. The formula that matters is Accuracy x Coverage - a tool that's 90% accurate but only covers 40% of your list loses to one that's 80% accurate with 85% coverage.
Go4Database's 25% bounce rate from a real user doesn't match their 95% accuracy claim. That gap tells you everything. In our experience, tools without a published refresh cycle are fighting data entropy - and losing (more on email deliverability fundamentals). The same Salesfinity research estimates bad phone data costs reps $7,500/year in wasted dial time alone. Bad email data compounds even faster through domain reputation damage (track email reputation tools if you’re scaling outbound).
A Stronger Alternative to Both
The results speak for themselves: Snyk's 50-person AE team dropped bounce rates from 35-40% to under 5% and grew AE-sourced pipeline 180%. Stack Optimize built to $1M ARR while maintaining 94%+ deliverability and under 3% bounce rates across all clients (especially when paired with sales prospecting techniques that reduce spray-and-pray).
At $0.023/contact, Go4Database sounds cheap - until 25% bounce. Prospeo delivers verified emails at ~$0.01 each with 98% accuracy. That's lower cost per valid contact and zero domain reputation risk.
Pay less per verified email than Go4Database charges per bounce.
Final Verdict
If you need cheap bulk email lists and can stomach cleanup, Go4Database gets you volume at $0.023/contact. For direct-dial mobile numbers - especially in the Indian market - ReachFast's mobile-first approach is worth testing. For teams where deliverability and data freshness actually matter, Prospeo's 7-day refresh and 98% accuracy make it the safer bet (compare options in Best Sales Prospecting Databases).
Regardless of which direction you lean: test all free tiers with your actual target list and measure bounce rates yourself before committing a dollar.
FAQ
Is Go4Database accurate?
Go4Database claims 95-100% email accuracy, but a real user reported roughly 25% bounce rates in live sequences. That gap suggests data freshness issues. The free trial lets you test against your own ICP - run at least 200 contacts through verification before buying.
Is ReachFast legit?
Yes. ReachFast holds a 4.5/5 rating across 45 reviews on G2, Trustpilot, and Software Advice. It's legitimate but small. Watch for duplicate records and incomplete contact data, which multiple reviewers have flagged.
How do Go4Database and ReachFast compare on pricing?
Both start near $35/month. Go4Database's Nano plan delivers 18,000 contacts/year via CSV export only. ReachFast's H-beta plan includes API access but fewer credits. Factor in bounce-adjusted cost: a 25% bounce rate effectively raises Go4Database's per-contact cost by 33%.
