Span Global Services vs WarpLeads (2026 Review)
This isn't a fair comparison. Span Global Services is a managed list broker - you tell them what you want, pay upfront, and hope the data's good. WarpLeads is a self-serve database where you pull unlimited leads for $99/mo and clean them yourself. If you're weighing these two, think catering company versus grocery store. Here's what actually matters.
30-Second Verdict
Span Global Services Overview
Use this if: You need a managed service to build hyper-targeted lists across niche verticals like healthcare or government and you can't find the segments elsewhere.
Skip this if: You value your money. Span claims 296M B2B contacts across 175 countries with "100% accuracy." The Trustpilot reviews tell a different story - one reviewer wrote that "every single one of the emails was fake," and another reported "bad data, wrong people, made up job titles" before support went silent. That's not a one-off complaint. It's a pattern.
Pricing is quote-based, with minimum project sizes typically starting around $1,000+. One Trustpilot reviewer paid PS1k for 10,000 contacts, putting per-contact cost somewhere around $0.05-$0.30 depending on targeting. That's steep for data multiple users say doesn't work. And because Span emphasizes inquiry forms and samples rather than transparent self-serve pricing, you're often buying before you can truly pressure-test quality at scale.
WarpLeads Overview
WarpLeads takes the opposite approach: give everyone access to everything and let them sort it out. The Unlimited Monthly plan runs $99/mo with truly unlimited exports from 100M+ leads and 20M+ companies. There's a free tier (30 contacts/month) for testing, and no refunds once you're in.
The catch is quality. WarpLeads' own help center calls email verification after export "mandatory," and they typically see around 70% valid emails after cleaning. That means roughly 30% of what you export is junk. API access requires quarterly billing starting at $299/mo ($897 upfront) for 500K leads/month, with a 10-day free trial available.
In our experience, the math still works for volume-first teams. At $99/mo unlimited, even at 70% validity, your cost per usable contact lands around $0.01-$0.02 once you add a cheap verifier. But you're trading time for money every single month - and that trade gets old fast.
WarpLeads gives you 70% valid emails. Span's users report even worse. Prospeo delivers 98% accuracy through 5-step verification before data ever reaches you - no third-party cleaner required.
Skip the cleaning step. Get sequence-ready contacts from day one.
Head-to-Head Comparison
| Pricing | Quote-based; projects start ~$1K+ | Free-$99/mo unlimited | Free tier; ~$0.01/email |
| Database size | 296M (claimed) | 100M+ (claimed) | 300M+ profiles |
| Email accuracy | "100%" (claimed) | ~70% valid after cleaning | 98% verified |
| Model | Managed broker | Self-serve | Self-serve |
| API access | Not public | $299+/mo (quarterly) | Yes, included |
| Refund policy | Not public | No refunds | Cancel anytime |
| Trustpilot | 2.0/5 (13 reviews) | Not prominent | N/A |
WarpLeads wins on cost per contact. Prospeo wins on accuracy and workflow speed. Span loses on both.
What Real Users Say
The Trustpilot pattern on Span is consistent. Reviewers describe paying for data, receiving unusable contacts, and getting ghosted by support. "Bad data... wrong people, made up job titles" appears across reviews spanning multiple years. SoftwareSuggest shows two positive reviews at 5/5, but the 13 Trustpilot reviews averaging 2.0/5 are hard to ignore.
Reddit sentiment on WarpLeads is split. One poster on r/Emailmarketing called the quality "terrible (high bounce rate, old emails)" even after verification through Apollo. But another user ran an A/B test across six databases - 500 contacts per platform - and WarpLeads delivered 9% bounce, 7.1% reply rate, and $22 per qualified lead, beating Apollo, ZoomInfo, and four others.
Both experiences can be true. We've seen this before with volume-first databases: quality varies wildly by segment, and the tool rewards users who treat it as raw material, not finished product.
Why Neither Is Enough
Here's the thing: if your average deal size is under $25k, you probably can't afford to waste 30% of your outreach on bad data. The sender reputation damage alone costs more than any data subscription.
WarpLeads explicitly requires verification after export. Span markets aggressive accuracy claims that Trustpilot reviewers consistently contradict.
Prospeo verifies data at the point of delivery. Every email goes through a 5-step verification process before it reaches you, which is why accuracy sits at 98%. The database covers 300M+ professional profiles with 143M+ verified emails, all refreshed on a 7-day cycle - the industry average is 6 weeks. Pricing is credit-based at roughly $0.01 per email, with a free tier of 75 emails per month. No contracts, no quarterly billing traps. Data arrives ready to sequence, and with 30+ search filters including buyer intent, technographics, and headcount growth, you're getting targeting precision that neither Span nor WarpLeads can match.
At $0.01 per email with 98% accuracy, Prospeo costs less than WarpLeads after you add a verifier - and you get 30+ filters, buyer intent data, and a 7-day refresh cycle instead of stale lists.
Better data, less work, same budget. Start with 75 free emails.
Final Verdict
WarpLeads at $99/mo is hard to beat on pure economics if you'll run your own verification. Span Global Services' track record doesn't justify the risk at any price point - look elsewhere for managed lists.
When comparing these two, the real question is whether cheap volume or reliable accuracy matters more to your pipeline. For accurate, ready-to-use data without a verification step, Prospeo is the clear pick.
You don't need a lot of data. You need accurate data. A 70% valid rate means 30% of your outreach is wasted effort, burned sender reputation, and lost time. Start with accuracy and work backward from there.
FAQ
Is WarpLeads data accurate without verification?
No. Their own help center states verification is "mandatory," with roughly 70% valid emails after cleaning. Budget $20-$50/mo for a third-party verifier like ZeroBounce or NeverBounce before loading contacts into any sequencer.
Is Span Global Services legit?
Span Global Services is a registered company, but Trustpilot shows 2.0/5 across 13 reviews. Multiple reviewers report fake emails, fabricated job titles, and unresponsive support after payment. Request a verified sample list before committing any budget.
What's a more accurate alternative to both?
Prospeo delivers 98% email accuracy with real-time 5-step verification, a 7-day data refresh cycle, and a free tier of 75 emails per month. No post-export cleaning required - contacts arrive sequence-ready.
How much does WarpLeads cost per usable lead?
At $99/mo unlimited with ~70% validity, your effective cost per usable contact is roughly $0.01-$0.02 after adding a third-party verifier. That's cheap, but the time spent cleaning and the deliverability risk from bounced emails add hidden costs most teams underestimate.
