Endole vs WarpLeads: Different Tools, Different Jobs
Comparing Endole and WarpLeads is like comparing a magnifying glass to a firehose. One gives you deep UK business intelligence - ownership structures, credit risk, director histories. The other blasts you with millions of bulk contact records at rock-bottom prices. We couldn't find a direct comparison of these two tools anywhere online, and honestly, that makes sense: they solve completely different problems.
30-Second Verdict
Pick Endole if you need UK company research, due diligence, monitoring, or credit reports. It's a business intelligence tool first - not a bulk prospecting database.
Pick WarpLeads if you want dirt-cheap bulk lead exports and you're willing to verify every email yourself before sending.
What Is Endole?
Endole is a UK-focused business information platform built for corporate risk, sales research, and compliance. It pulls together company and director data, ownership structures (including group hierarchies and PSCs), financials, and live credit scores in one place. Think of it as Companies House on steroids, with risk scoring layered on top.
Pricing runs £39/mo or £299/year (roughly £25/mo). It carries a 4.6/5 on G2, though based on just 5 reviews. Reviewers highlight accuracy and the usefulness of UK/EU company data. The consistent knock? Limited US coverage. If you need deep US-specific financial and filing data, look elsewhere.
What Is WarpLeads?
WarpLeads is a bulk B2B contact database positioned as the budget option. Third-party write-ups put it at around 100M records, with filters for job title, location, company size, industry, and technographics. The unlimited plan runs $99/mo with a free tier offering 30 contacts/month.
Here's the thing about WarpLeads that catches people off guard: API access is a separate add-on at $299-$999/month, billed quarterly, and it requires an active Unlimited subscription on top of that. WarpLeads documentation also notes that only around 10% of records include phone numbers, and the workflow is built around exporting lists at scale. In practice, teams treat WarpLeads exports as raw material and run them through a separate email verifier before sending anything. There's also a strict no-refunds policy.
Where WarpLeads does shine is rapid ICP testing. One user described testing 12 ICP variations in a single month without worrying about credit limits. That's a legitimate use case if you're still dialing in targeting.
If your bounce rate tolerance is above 5%, WarpLeads works for experimentation. But the moment you care about sender reputation, unverified bulk data becomes a liability.
WarpLeads gives you volume. Endole gives you UK company intel. Neither gives you verified contacts ready to send. Prospeo delivers 98% accurate emails from 300M+ profiles - no separate verifier, no bounced campaigns, no burned domains.
Skip the bulk export cleanup. Start with data that's already verified.
Side-by-Side Comparison
| Dimension | Endole | WarpLeads |
|---|---|---|
| Primary use | UK company intel, risk, compliance | Bulk contact exports |
| Data types | Company/director info, ownership, financials, credit reports | Emails, limited phones |
| Geography | UK/EU focused | Global |
| Phone coverage | Not a phone-first dataset | ~10% of records |
| Email verification | Not an email verification tool | Not included |
| Pricing | £39/mo (£299/yr) | $99/mo unlimited; free (30/mo) |
| Best for | UK due diligence + company research | Cheap ICP testing |
These tools barely overlap. One's a research platform for UK business data; the other's a bulk export engine.
Data Quality: Where It Falls Apart
We've seen teams burn through sender reputation sending unverified bulk exports, and WarpLeads data is a prime culprit. A B2B marketing company posted on Reddit that WarpLeads data quality was "terrible" - high bounce rates and stale emails, even after running records through Apollo's verification. That's a rough outcome when you've already paid for the data and the verification tool.
If you want the benchmarks and fixes behind that, start with email bounce rate and a full email deliverability guide.
Cold email best practices target under 3% bounce rates. WarpLeads' own help docs make it clear you're not getting universal phone coverage either. If you use WarpLeads, plan on verification and list hygiene as non-negotiable parts of the workflow - and budget accordingly.
Endole has the opposite tradeoff. Its company and director intelligence is strong for UK research and due diligence, but it's not built as a verified outbound contacts platform.
Better Option for Outbound
Let's be honest: if your actual goal is booking meetings, neither Endole nor WarpLeads is the right tool.
Most teams are better served by a dedicated sales prospecting database and a repeatable cold email sequence.
Filters go beyond basics: buyer intent powered by Bombora, technographics, job changes, headcount growth, and funding signals. The free tier gives you 75 verified emails and 100 Chrome extension credits per month. No contracts, no sales calls, self-serve from day one.
If you're building a full outbound motion, pair data with proven sales prospecting techniques and tight sales follow-up templates.
Reddit users called WarpLeads data "terrible" even after running it through Apollo's verifier. Prospeo's 5-step verification and 7-day refresh cycle mean you skip the stale-data roulette entirely - at roughly $0.01 per verified email.

FAQ
Is WarpLeads data accurate enough for cold email?
A Reddit thread from a B2B marketing company called the quality "terrible," citing high bounce rates and old emails even after external verification. WarpLeads is built for volume. If deliverability matters, budget for a separate verifier or use a platform with built-in verification and 98%+ email accuracy.
Can Endole be used for outbound prospecting?
Endole is mainly for UK company intelligence - ownership structures, credit risk, director details, and monitoring. Some plans include exportable contacts, but it isn't designed as a verified outbound contact database. Teams running outbound campaigns need a dedicated sales data platform.
What's the cheapest way to get verified B2B contacts?
WarpLeads is $99/mo for unlimited exports, but you'll need a separate email verifier on top. Prospeo's free tier gives you 75 verified emails/month at zero cost, with paid plans at roughly $0.01 per email - already verified, no extra tools needed.
