ContactOut vs Endole: Different Tools, Different Jobs
Comparing ContactOut to Endole is like comparing a phone book to a credit report. They don't compete in any practical buying decision, and if you're trying to choose between them, you've probably misidentified your problem.
ContactOut finds email addresses and phone numbers for sales outreach and recruiting. Endole pulls UK company intelligence - financials, credit reports, ownership structures. On G2, they sit in entirely different primary categories. Let's clear up the confusion fast.
30-Second Verdict
What Is ContactOut?
ContactOut is a Chrome extension and search platform that pulls email addresses and phone numbers from professional profiles. It's popular with recruiters and SDRs who need contact info fast.
Use this if: you're a recruiter or solo SDR who needs a handful of contacts per day. The free tier gives you 5 emails and 5 phones daily - enough to test the waters.
Skip this if: you're running outbound at any real volume. The Email plan at $99/month caps you at 300 exports. The Email+Phone plan at $199/month bumps that to 600. That sounds reasonable until you realize a five-person SDR team burns through those credits in the first week of a campaign, and then everyone sits idle waiting for the reset.
Even the "unlimited" tiers come with fair-use caps - roughly 2,000 emails and 1,000 phones per month, plus about 91 lookups per day. No overage options. You just wait.
ContactOut carries a 4.4/5 on G2 from 109 reviews. Praise centers on ease of use. Complaints center on credit limits and outdated contacts - the data can be strong, but stale records still slip through, and there's no way to flag or filter them before export.
What Is Endole?
Endole is a UK-focused business intelligence platform that aggregates data from Companies House and other official sources into a single dashboard - ownership structures, credit risk, financial health, director details, and group hierarchies.
Companies House processes billions of data requests annually and its free tooling comes with real-world limitations like rate limits, downtime, and gaps in what's easy to analyze at a glance. Endole packages that research into a more usable workflow. The platform claims over 100,000 professionals use it daily.
Use this if: you're a finance team, credit analyst, or sales ops professional researching UK-registered companies. Pricing runs around £39/month or £299/year, with a free trial available. For pay-per-use UK credit checks, some finance teams prefer Veriphy at about £3/check in bulk bundles.
Skip this if: you need US company data or individual email addresses. The top complaint on G2 is limited US coverage - no SEC filings, no US credit scores, and missing US-specific financial depth. Endole earns a 4.6/5, but from only 5 reviews, so treat that rating directionally.
ContactOut's 300-export cap and stale data aren't just inconvenient - they stall pipelines. Prospeo refreshes every 7 days, verifies emails through a 5-step process, and delivers 98% accuracy at roughly $0.01 per email. Snyk's 50 AEs dropped bounce rates from 35-40% to under 5% after switching.

These tools don't belong in the same head-to-head. One finds people, the other researches companies. If someone told you to pick between them, they misunderstood your requirements.
Which Tool Do You Actually Need?
You need UK company financials, credit reports, or ownership data. Endole. Nothing ContactOut offers touches this.
You need emails and phone numbers for outreach. ContactOut works, but the credit caps bite faster than most teams expect. We've seen teams burn through a month's allocation in under two weeks, then scramble for workarounds.
You need both company intelligence and contact data. You're buying two tools. No single platform replaces both.
Here's the thing: most people landing on a "ContactOut vs Endole" comparison actually need a contact data tool, not a company intelligence platform. And if that's you, ContactOut isn't the strongest option anymore. The consensus on r/coldemail is consistent - accuracy and bounce rates matter more than feature count. That's where stale-data issues become a dealbreaker.
A Stronger Option for Contact Data
Where ContactOut charges $99/month for 300 exports, Prospeo's email finder runs at roughly $0.01 per email with no arbitrary daily limits. Data refreshes every 7 days (the industry average is 6 weeks), so you're not emailing people who changed jobs two quarters ago.
Prospeo's 5-step verification process - including catch-all handling, spam-trap removal, and honeypot filtering - delivers 98% email accuracy. Customers like Snyk dropped bounce rates from 35-40% to under 5% after switching, while generating 200+ new opportunities per month across 50 AEs. That's not a marginal improvement; it's the difference between a healthy sending domain and one that's circling the spam folder.
If you're evaluating tools in this category, start with a shortlist of SDR tools and compare how they handle email verification and email deliverability end-to-end.
The free tier gives you 75 verified emails per month - enough to run a real test, not just kick the tires. No contracts, no sales calls, self-serve onboarding. Native integrations with Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay mean it drops into existing workflows without friction.
If you're building lists at scale, it also helps to understand lead enrichment and how data enrichment services fit into your outbound stack.
You came here looking for contact data, not UK company financials. Prospeo gives you 300M+ verified profiles with 30+ search filters - buyer intent, technographics, job changes, funding - so you find the right people and actually reach them. 75 free emails per month, no credit card, no contracts.
Get more contacts in a week than ContactOut gives you in a month.
FAQ
Are ContactOut and Endole competitors?
No. ContactOut finds individual emails and phone numbers for outbound prospecting. Endole provides UK company intelligence - financials, credit reports, ownership structures. They serve completely different use cases and shouldn't appear in the same shortlist.
Is ContactOut's unlimited plan really unlimited?
Not exactly. Fair-use caps apply - roughly 2,000 emails/month and 1,000 phone numbers/month per user, with about 91 lookups per day. No overage options exist. You wait for the monthly reset or negotiate a custom Team/API plan.
What's a good free alternative to ContactOut for finding emails?
Prospeo offers 75 verified emails plus 100 Chrome extension credits per month on its free plan - no credit card required. That's significantly more useful than ContactOut's 5-per-day cap, especially when you factor in the 7-day data refresh cycle that keeps records current.
