ContactOut vs Endole: B2B Contact Data Tools Compared (2026)

You typed both names into a search bar because they sound like they solve the same problem. They don't. ContactOut and Endole live on opposite ends of the B2B data map, and picking the wrong one wastes a quarter of budget on records you can't act on.

TL;DR — ContactOut vs Endole in 30 seconds#

• ContactOut is a global contact finder: personal and work emails plus mobile numbers scraped and matched from LinkedIn profiles. Best for recruiters and sales reps who prospect people.
• Endole is a UK company intelligence and credit-data platform built on Companies House filings. Best for finance, risk, and account research on British businesses.
• They barely overlap. ContactOut answers "how do I reach this person?"; Endole answers "is this UK company real, solvent, and worth pursuing?"
• Neither gives you clean, verified work emails at scale across every region — that's where a dedicated email finder fills the gap.
• If your outbound is international and email-first, ContactOut is closer to what you want, but you'll still want a verifier bolted on.

What is ContactOut?#

ContactOut is a contact-enrichment tool that pulls emails and phone numbers tied to LinkedIn profiles. You install a Chrome extension, browse a profile, and it surfaces personal Gmail addresses, work emails, and mobile numbers it has matched to that person.

Its whole pitch is people-level reach. Recruiters love it because a personal Gmail lands in an inbox that isn't filtered by a corporate gateway. Sales teams use it to skip the gatekeeper and hit a decision-maker's mobile.

The tradeoffs are the ones you'd expect from any LinkedIn-derived dataset:

• Coverage is people-first, not company-first. You find individuals; you don't get a clean org chart or firmographic filters as rich as a dedicated database.
• Personal emails carry consent and deliverability risk. A personal Gmail is great for a recruiter and a compliance headache for a GDPR-regulated outbound campaign.
• Verification is not the core job. You still want to run addresses through an email verifier before you load a sending sequence.

What is Endole?#

Endole is a UK-focused business intelligence platform. It aggregates Companies House data — directors, filings, accounts, credit scores, group structures — into search tools and the "Endole Explorer" for building lists of British companies by SIC code, region, turnover, and financial health.

This is not a prospecting-email tool. Endole is what a credit analyst, a due-diligence researcher, or a UK-only field sales team reaches for when the question is about the company: Who owns it? Is it filing on time? What's the credit risk? Which other entities share directors?

Where Endole is strong:

• Depth on UK entities. Filing history, financials, and director networks that a global contact tool never touches.
• Risk and compliance workflows. Credit scoring and monitoring that sales-only tools ignore.
• List-building by firmographics within Great Britain.

Where it stops:

• No meaningful contact-level email/phone data for outreach the way ContactOut delivers.
• UK only. If your ICP includes the US, EU, or APAC, Endole is a dead end.

ContactOut vs Endole: the core difference#

Here's the honest framing. These two tools answer different questions, so "which is better" depends entirely on your motion.

Read that table twice before you buy either one. If your team runs cold email into North America, Endole cannot help you and no discount changes that. If your team underwrites UK credit lines, ContactOut's mobile numbers are noise.

Which one fits your use case?#

Use this checklist to route yourself. Match the row to your actual weekly work, not your aspiration.

1. You prospect individuals across multiple countries → ContactOut is the closer fit. You need person-level email and phone, and Endole doesn't cross the Channel.
2. You research UK companies for risk, credit, or M&A → Endole wins outright. Director networks and filing history are its home turf.
3. You run high-volume cold email and need deliverability → Neither is complete. Pair a contact finder with dedicated verification; ContactOut alone will still bounce.
4. You want work emails by company domain, worldwide → Reach for a domain search built for exactly that, not a LinkedIn scraper or a UK filings database.
5. You need enriched CRM records — job title, company, socials, verified email — → Layer a data enrichment step; single-purpose tools leave gaps.
6. You care about GDPR posture on outreach → Endole's public-filing data is low-risk; ContactOut's personal emails demand a lawful-basis review before you send.

How accurate is the data?#

Accuracy means two different things here, which is the trap.

Endole's data accuracy is essentially the accuracy of Companies House — it's authoritative for what it covers because it mirrors a public register. If a UK company filed accounts, Endole reflects them. The limit isn't accuracy; it's scope. You will not find a marketing manager's work email there.

ContactOut's accuracy is the accuracy of LinkedIn matching plus its own guessing. Personal Gmail hit rates are strong; work-email guesses vary by company and get stale as people change jobs. Independent reviews on G2 reflect the usual pattern for LinkedIn-derived tools: good for finding a contact point, uneven on whether that specific work address is still live.

That's why the verification step matters regardless of which tool you start with. A found email is a hypothesis. Running it through a catch-all verifier or standard verification turns the hypothesis into something you can safely load into a sequence without torching your sender reputation.

Pricing: ContactOut vs Endole#

Both use quote-and-tier models that shift by seat and volume, so treat these as directional rather than a locked quote. The structural difference is what you're paying for.

The mistake teams make is buying the expensive tier of the wrong tool. Paying ContactOut's premium seats to occasionally check a UK company, or Endole's data plan to occasionally find an email, means overpaying for a feature you use twice a month. Buy the tool that matches your daily job and add a cheap, focused tool for the edge case.

For reference on what focused, transparent tooling costs, Tomba pricing runs a free tier at 25 searches per month, Starter at $49/mo, Growth at $99/mo, and Pro at $249/mo — email finding and verification in one stack rather than split across a scraper plus a separate register.

Where a dedicated email finder beats both#

Most people searching "contactout vs endole" actually have a third need neither tool centers: clean, verified work emails at scale, in any region, tied to a domain or a name.

That's a different product category from a LinkedIn contact scraper and from a UK filings database. A purpose-built finder lets you:

• Search by company domain and pull every discoverable work email with confidence scores.
• Find a specific person's work email from name + company without an extension babysitting each profile.
• Verify in the same workflow so bounces are caught before send, not after.
• Enrich records with title, company, and social links for CRM hygiene.
• Go global — no "UK only" ceiling, no dependence on a single social network's coverage.

This is the layer that makes ContactOut's finds safe to send and covers the outreach use case Endole was never built for. It's not either/or; it's the missing middle.

The verdict#

Pick by question, not by feature list. If you're reaching people across borders, ContactOut is the nearer match — just add verification. If you're assessing UK companies' credit and structure, Endole is purpose-built and hard to beat within Britain. They are not substitutes, and any listicle that ranks one "above" the other is comparing a hammer to a tape measure.

But if your real job is outbound — finding and reaching decision-makers with emails that actually deliver — you want a finder-plus-verifier built for that, not a repurposed scraper or a credit register.

That's where Tomba fits. Use the Tomba Email Finder to find professional email addresses by domain, name, or company, verify them in the same flow, and keep your sender reputation clean across every region — no UK ceiling and no per-profile babysitting. Start on the free tier, then scale to Starter at $49/mo when your pipeline demands it.
