ContactOut vs Market Location: Different Tools, Different Jobs
Comparing ContactOut to Market Location is like comparing a screwdriver to a lumber yard. One's a self-serve email finder you install as a Chrome extension. The other is a UK B2B data vendor that's been operating since 1972. They don't compete, they barely overlap, and if you're trying to decide between them, you're probably confused about what one of them actually does.
"Market Location" often gets mistaken for a geo-targeting or location-based marketing tool. It isn't. It's a very specific UK data company - and that confusion is likely why this comparison exists at all.
30-Second Verdict
ContactOut is the right pick if you need a self-serve Chrome extension for finding emails and phone numbers, especially in the US and Canada.

Market Location is the right pick if you're a UK marketing team buying bulk B2B datasets for telemarketing or direct mail, and you're comfortable with custom contracts.
Skip both if you need verified global emails with strong UK coverage and no custom contract. Prospeo covers 300M+ profiles at 98% email accuracy, starts free, and doesn't require a sales call.
What Is ContactOut?
ContactOut is a Chrome extension built for SDRs and recruiters who need quick access to emails and phone numbers while browsing professional profiles. The database covers 800M+ profiles with 400M+ emails, and it holds a 4.4/5 on G2.

Here's the thing about accuracy, though. ContactOut's own benchmark on 200 profiles shows 90% valid emails. In practice, real-world accuracy tends to land closer to 70-75% - a gap that matters a lot if deliverability is on the line. We've seen this pattern across multiple tools that self-report high accuracy on tiny sample sizes; the numbers always look worse at scale. Their 6sense market share sits at 3.80%, ranking #7 in email finders, with 67% of customers based in the US.
Pricing is messy depending on which page you're looking at. Third-party summaries list the Sales plan at $79/month, while ContactOut also references plans starting at $29/month and an "Unlimited sales users for $299" option. The free tier is similarly unclear - some materials say 10 credits/month, others say 15 credits/day. If you're evaluating this tool, pin down the actual numbers before committing.
G2 ranks Apollo.io as the top ContactOut alternative in the self-serve category. Apollo is strong for all-in-one prospecting, but it still won't solve the UK bulk data problem that Market Location addresses. (If you're comparing more tools in this category, see our breakdown of email finder options.)
What Is Market Location?
Market Location is a UK-focused B2B data vendor, part of the 118 Group, headquartered in Sutton Coldfield. They offer 2.4M+ UK B2B contact records with 98% phone connectivity, telemarketing data covering 1.6M+ records, intent data tied to 3.9M+ IP addresses, and social media data including 1M+ handles - all UK-focused, all custom-priced.
There's no Chrome extension, no monthly subscription, no credit system. You negotiate a contract, specify your data requirements, and receive bulk records. Expect annual contracts typical of UK data-as-a-service providers, roughly £5,000-£20,000+/year depending on scope. They operate under GDPR legitimate interests with ICO registration, and they don't have a meaningful review footprint on mainstream SaaS review sites like G2 or Capterra. Datarade shows no reviews yet.
One Reddit thread we found features someone who received Market Location's GDPR Article 14 notice and called it "marketing BS" - which tells you something about how their data sourcing is perceived outside the industry.

ContactOut's real-world accuracy drops to 70-75%. Market Location locks you into custom UK contracts. Prospeo delivers 98% email accuracy across 300M+ global profiles - including strong UK and EU coverage - at $0.01/email with no contract required.

Key Differences at a Glance
| Dimension | ContactOut | Market Location |
|---|---|---|
| Product type | SaaS email finder | DaaS provider |
| Pricing | From ~$29/mo (some sources list $79/mo for Sales) | Custom (~£5K-£20K/yr) |
| Geographic focus | US/Canada-heavy | UK-focused |

| Compliance | Vendor-led compliance features | GDPR/PECR + ICO |

| Self-serve | Yes | No |

This table makes them look comparable, but they serve fundamentally different buyers. ContactOut is for individual reps finding one contact at a time. Market Location is for marketing teams licensing thousands of UK records in bulk. The overlap is almost zero.
Which Should You Choose?
Go with ContactOut if you need self-serve prospecting with a Chrome extension, your target market is primarily US/Canada, and you want monthly billing with no long-term commitment.
Go with Market Location if you're running UK-specific telemarketing or direct mail campaigns, you need bulk datasets rather than one-off lookups, and your team is comfortable negotiating custom data contracts.
Pick neither if you need verified global data including strong UK and EU coverage, you want self-serve access without custom contracts, and email accuracy above 90% matters to your deliverability. That last scenario is where most teams actually land.
A Stronger Option for Most Teams
Let's be honest - most people landing on this comparison aren't locked into a UK-only or US-only market. They need global coverage with self-serve access and emails that actually reach inboxes.

Prospeo gives you ContactOut's self-serve workflow with data quality and global coverage that neither tool matches at this price point. The database covers 300M+ professional profiles globally - including strong UK and EU coverage - with 98% email accuracy verified across 143M+ emails. That's not a vendor benchmark on 200 profiles; it's a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering built on proprietary infrastructure.

We've tested the mobile data extensively: 125M+ verified mobile numbers with a 30% pickup rate, a 7-day data refresh cycle (the industry average is six weeks), and 30+ search filters including buyer intent powered by Bombora. The Chrome extension has 40,000+ users and works across professional profiles and company websites.
Pricing is straightforward. The free tier gives you 75 emails and 100 Chrome extension credits per month. Paid plans run ~$0.01/email with no annual contracts - a fraction of ContactOut's cost and infinitely more accessible than Market Location's custom quotes. One customer, Stack Optimize, built from $0 to $1M ARR while maintaining 94%+ deliverability and sub-3% bounce rates across all clients. That's the kind of data quality that compounds.
If your average deal size is under five figures and you're selling outside a single country, you don't need a custom data contract or a tool with 70% real-world accuracy. You need verified emails that land in inboxes. That's the whole game. (For more ways to build pipeline without overpaying for data, start with these sales prospecting techniques.)

Stack Optimize built a $1M agency on Prospeo data with 94%+ deliverability and sub-3% bounce rates across every client. That's what happens when emails are verified through a 5-step process with catch-all handling and spam-trap removal - not benchmarked on 200 profiles.
75 free emails per month. No sales call. No custom quote. Just verified contacts.

Does ContactOut have good UK coverage?
ContactOut's database is global but US-weighted. Per 6sense data, 67% of customers are US-based, with only 4.8% in the UK. Coverage exists but depth and accuracy are concentrated in North America.
What's the most affordable option with UK and US coverage?
Prospeo's free tier includes 75 emails and 100 Chrome extension credits monthly, covering 300M+ global profiles with 98% accuracy. No contracts required - paid plans start at roughly $0.01 per email.
Is there a real comparison between ContactOut and Market Location?
Not really. They're different product categories - a self-serve email finder vs. a UK bulk data vendor. Most teams searching this comparison actually need a single tool with global coverage and self-serve access, which neither provides on its own.
