B2B Lists vs ContactOut: List Broker or Discovery Tool?
B2B Lists vs ContactOut is a choice between two fundamentally different models. B2B Lists sells you a static file - a one-time purchase of contacts segmented by industry and geography. ContactOut gives you a Chrome extension to pull emails and phones from professional profiles on demand. Same goal, completely different mechanics, and the tradeoffs matter more than most comparison articles admit.
Reps spend roughly 68% of their time on non-selling activities, and bad data is a huge chunk of that waste. So let's figure out which tool actually saves you time - or whether you should skip both.
Quick Verdict
- B2B Lists wins if you need a one-time USA phone list for a specific industry and don't plan on ongoing outbound.
- ContactOut wins if you're prospecting daily from professional profiles and need a lightweight Chrome extension workflow.
B2B Lists - What You Get
B2B Lists is a traditional list broker. You tell them the industry, geography, and role you want, they send you a file. Their database covers 60M+ USA business records with phone numbers on virtually all records, which makes it genuinely useful for cold calling campaigns.
The segmentation is the real selling point. You can slice by 100+ industries, geographic regions down to postal code, and executive roles like CEO, President, VP, owner, or manager. Positive Trustpilot reviews praise the segmentation accuracy and a replacement policy for bounced leads.
Here's the problem: Trustpilot sits at 3.9/5 from just 4 reviews, and one of those reports ~40% bounce rates with poor follow-through on replacements. The sample is small - treat this as a risk signal, not a verdict. But a 40% bounce rate will torch your sender reputation fast. Pricing is quote-based; expect roughly $0.10-$0.50 per contact depending on targeting and fields, with typical orders running $500-$5,000.
Use this if you need a quick USA phone list for a single campaign and you're willing to verify the data yourself before sending.
Skip this if you need ongoing, fresh data or you're running email sequences where deliverability matters.
ContactOut - What You Get
ContactOut takes a different approach entirely. It's a Chrome extension that overlays contact data on professional profiles, letting you grab emails and phone numbers as you browse. G2 rates it 4.4/5 across 109 reviews, and users consistently praise the ease of use and time savings.
The pricing tiers tell the real story, though. Free gets you 5 lookups per day and 5 exports per day. Market-cited pricing on annual billing commonly lists the Email plan at $49/mo with 300 exports per month, Email+Phone at $99/mo for 600 exports, and a Recruiter tier at $199/mo. G2 confirms a Sales plan at $79/mo. ContactOut's pricing page renders client-side, which makes direct comparison frustratingly difficult - a weird choice for a product that wants you to buy.
Let's do the math on exports. At $49/mo for 300 exports, you're paying about $0.16 per contact. At $99/mo for 600, it's ~$0.165. That adds up quickly if you're running any kind of volume.
In our audits of outbound programs, export caps are usually the real limiter, not "lookups." A recurring G2 complaint backs this up: the "unlimited" lookups language is confusing because exports are capped, and exports are what actually matter. Outdated contacts are the other recurring issue - users call out stale data, especially phone numbers. For a tool built around real-time discovery, that's a meaningful gap.
Head-to-Head Comparison

ContactOut's 4.4/5 G2 score looks great until you realize most of those reviews praise the concept - overlay contact data while you browse - not the data quality itself. A high-rated UX wrapped around stale data is still stale data.
B2B Lists gives you a file that decays on download. ContactOut caps your exports at 300-600/mo. Prospeo delivers 300M+ profiles with 98% email accuracy, 125M+ verified mobiles, and a 7-day refresh cycle - no export caps, no stale data, at ~$0.01 per email.
Stop rationing your pipeline. Start with 75 free verified emails.
The Problem with Both
Look, both models have a shelf-life problem. B2B Lists sells you a static file that starts decaying the moment you download it. We've seen list-broker files go stale within weeks - job changes alone make last-quarter lists unreliable. Verify before every send, suppress bounces immediately, and run enrichment on anything older than 90 days.
ContactOut gives you fresher data in theory, but the credit caps mean you're rationing access to your own pipeline. And without a published refresh cycle, "fresh" is an assumption, not a guarantee.
Reddit threads on r/b2bmarketing paint a consistent picture of purchased list pain: high bounce rates, recycled contacts your competitors already hit, and deliverability damage that takes months to repair. One practitioner burned through $15k on lead databases before switching strategies entirely.
Whether you're buying a file or exporting 300 contacts a month through a Chrome extension, the core question stays the same: is this data fresh enough to actually use?
How to Evaluate Accuracy
Don't trust vendor claims blindly. Run a sample through verification and check three things: hard bounce rate, wrong-domain matches where the email format is right but the person left the company, and catch-all domain handling that inflates "valid" counts without guaranteeing delivery. The industry average refresh cycle is 6 weeks. Any tool refreshing slower than that is selling you yesterday's data at today's prices.
Decision Framework
Before you pick a tool, answer three questions:
Is this a one-time campaign or ongoing outbound? A one-time USA phone blitz - B2B Lists can work if you verify first. Ongoing sequences need a tool that refreshes.
How many contacts do you need per month? Under 300, ContactOut's free or entry tier covers you. Over 300, you'll hit export caps fast and the per-contact cost climbs steeply.
Does deliverability matter to your business? If you're sending email at any volume, a single bad batch can tank your domain reputation for months. Static files and unverified exports are a common cause of domain damage in outbound programs. If your answer here is yes - and it should be - neither tool gives you the safety net you need.
A Stronger Third Option
Prospeo's database covers 300M+ profiles with 98% email accuracy, refreshed every 7 days - not 6 weeks. At ~$0.01 per email with no monthly export caps, it undercuts both B2B Lists' per-contact pricing and ContactOut's $0.16+ per export. The free tier gives you 75 verified emails and 100 Chrome extension credits per month, and native integrations with Salesforce, HubSpot, and Instantly mean data flows straight into your stack without manual CSV wrangling.
If you're comparing options beyond these two, start with a broader list of sales prospecting databases and email list providers to sanity-check pricing and data models.
At $0.10-$0.50/contact from B2B Lists or $0.16/export from ContactOut, you're overpaying for data neither tool guarantees is fresh. Prospeo runs ~$0.01/email with 5-step verification, catch-all handling, and spam-trap removal - the same data infrastructure 15,000+ companies trust.
Pay 90% less per contact and bounce under 4%. See for yourself.
The Bottom Line
When weighing B2B Lists vs ContactOut, the right pick depends on your workflow:
- Pick B2B Lists if you need a one-time USA phone list, you have budget for a bulk file, and you'll verify every record before sending.
- Pick ContactOut if you prospect from professional profiles daily, need fewer than 300 exports per month, and can tolerate occasional stale data.
- Pick Prospeo if you run ongoing outbound, care about deliverability, or need more than 300 verified contacts per month without export caps.
Most teams running real outbound programs outgrow both B2B Lists and ContactOut within a quarter. The export caps, stale data, and lack of intent signals make them starter tools - fine for testing, limiting at scale.
FAQ
Is B2B Lists data accurate?
Some Trustpilot reviewers confirm well-targeted lists, but one reviewer reported ~40% bounce rates with poor support follow-through. With only 4 reviews total, the sample is too small for a verdict. Always run purchased lists through an email verification tool before sending - your sender reputation depends on it.
Why does ContactOut say "unlimited" if there are caps?
ContactOut's "unlimited" refers to lookups, not exports. You can browse and view contact data freely, but exporting contacts is capped at 300-600 per month depending on your plan. Exports are the binding constraint and a recurring G2 complaint. Ignore the "unlimited" headline and focus on the export number for your tier.
Is it legal to use purchased B2B lists?
GDPR, CAN-SPAM, and CCPA all impose specific requirements on outreach data. Under GDPR, you need a lawful basis and must honor opt-out requests. Under CAN-SPAM, you need accurate sender info and a working unsubscribe mechanism. Purchased lists carry extra risk because you can't verify consent history. Scrub against suppression lists and consult legal counsel for EU contacts.
What's the cheapest way to get verified B2B emails?
Prospeo's free tier gives you 75 verified emails per month at zero cost. Paid plans run ~$0.01 per email with no monthly export caps - significantly cheaper than ContactOut's $0.16+ per export or B2B Lists' $0.10-$0.50 per record. The 98% accuracy rate means you aren't paying to clean bad data afterward.
