ContactOut vs LeadIQ: Which One Actually Delivers Accurate Data?
Comparing ContactOut vs LeadIQ comes down to three things: pricing transparency, data accuracy, and how each tool fits your workflow. ContactOut scores a 4.4/5 on G2 from 109 reviews. LeadIQ sits at 4.2/5 from 1,160 reviews. That gap in review volume tells you something - LeadIQ has far more users putting it through the wringer, and the complaints are well-documented.
Both tools promise accurate B2B contact data. Neither fully delivers on that promise.
30-Second Verdict
ContactOut wins for solo prospectors and recruiters who need simple, per-profile email and phone lookups without complex integrations.
LeadIQ wins for SDR teams on Salesforce or HubSpot who need native workflow integrations with Salesloft, Outreach, and Gong.

ContactOut - Fast for Solo Lookups
ContactOut's Chrome extension feels fast for one-off lookups. The interface is dead simple, the 300M professional database covers most people you'd want to reach, and the company claims it's trusted by 1.4M professionals across over 76% of Fortune 500 companies. For a recruiter or solo prospector who lives in a browser extension, it's hard to beat the workflow.
Skip this if you need team-level access or high-volume prospecting. Here's the thing: ContactOut's "unlimited" plans aren't unlimited. Fair-use policies cap you at roughly 2,000 emails and around 800-1,000 phone numbers per month.
The $99/mo Email plan gives you 300 exports/month. The $199/mo Email+Phone plan bumps that to 600 exports. Both limit you to one user per company - a team of three SDRs means custom pricing immediately, with no option to buy overages. There's also a free tier worth testing: 5 emails, 5 phones, and 5 exports per day. If you're building a broader outbound stack, compare options in our guide to SDR teams.
ContactOut caps exports at 600/mo. LeadIQ burns 11 credits per prospect. Prospeo gives you 98% accurate emails at $0.01 each - no fair-use caps, no credit tricks, and a 7-day data refresh that catches job changes both tools miss.
Stop paying more for data that bounces one in ten times.
LeadIQ - The Credit Math Problem
LeadIQ's integrations are best-in-class for SDR teams, but the credit system quietly punishes anyone who needs phone numbers. One email costs 1 credit. One phone number costs 10 credits. Need both for a prospect? That's 11 credits gone. A hundred prospects with full contact data burns 1,100 credits, and once you scale phone pulls, costs climb fast.
Where LeadIQ genuinely earns its price is the integration layer. Native connections to Salesforce, HubSpot, Salesloft, Gong, Outreach, and Clay with duplicate detection, 40+ firmographics pushed to CRM, and SOC 2 Type II certification. We've seen teams burn through LeadIQ credits in under two weeks, but the ones who get value are running tight CRM workflows where that data flows directly into sequences. LeadIQ also offers a free tier with 50 credits to test the waters. If you're evaluating CRM fit, see these examples of a CRM.
An analysis of 93 actual LeadIQ purchases found a median annual cost of $26,400, with deals ranging from $6,096 to $58,240. Average negotiation savings hit about 21%, so always push back on the first quote. (If you want a framework for that pushback, use an anchor in negotiation.)
Where Both Tools Fall Short on Accuracy
Let's be honest: neither ContactOut nor LeadIQ publishes independent accuracy benchmarks. That's the core problem with this entire comparison.
ContactOut's email accuracy runs around 90% based on third-party testing - decent, but one in ten emails still bounces. LeadIQ's accuracy story is worse: 72 G2 reviews specifically cite inaccurate data, and 40 reviews flag incorrect phone numbers. That's not a handful of edge cases. It's a pattern, and the consensus on r/sales threads tends to confirm that LeadIQ's phone data is the weakest link. If accuracy is your priority, it’s worth understanding email bounce rate and how to check if an email exists before you scale sends.
Pricing at Scale
LeadIQ's credit math is where costs spiral. An SDR needing email and phone for 100 prospects per week burns roughly 4,400 credits per month. Once you start adding credit packs to keep up with phone usage, your monthly spend climbs well past that $200/mo starting price.
ContactOut's $199/mo Email+Phone plan caps exports at 600/month with no overage option. Neither tool is transparent about what you'll actually pay at scale, which is frustrating when you're trying to build a budget for next quarter.
