ContactOut vs LeadMine: Which Email Finder Is Worth Your Money?
Listing features side by side doesn't tell you which tool is worth paying for. What actually matters in this ContactOut vs LeadMine comparison is cost per verified contact that lands in an inbox. Let's do that math, then talk about when you should skip both entirely.
30-Second Verdict
- ContactOut wins if you need the largest reach (700M-800M+ profiles, depending on the plan) and phone numbers, and you can live with opaque pricing and fair-use caps.
- LeadMine wins if you're budget-conscious, only need verified work emails, and want transparent pricing with a bounce-credit refund.
- Skip both if you need verified emails and mobile numbers without cap games or pricing confusion.
Here's the benchmark that matters: keep total bounces below 2% and hard bounces under 1%. Anything above that and you're torching your domain reputation.
ContactOut at a Glance
You'd reach for ContactOut if you're a recruiter or sales rep who needs the widest net possible. Their database sits at 700M+ profiles on the pricing page, with other materials citing 800M+. The Chrome extension works well for one-at-a-time prospecting, and the Email + Phone plan gives you 2,000 emails and 1,000 phone numbers per month - decent volume for individual contributors.
Skip this if you care about pricing transparency. One source reports the Email plan at $49/mo billed annually, while another puts it at $99/mo for what appears to be the same tier. That's not a rounding error.
The "unlimited" email label on paid plans is misleading, too. Fair-use caps limit you to 2,000 emails/month, 1,000 phones/month, and 300-600 exports/month depending on tier. Hit the cap and you're done until next month. G2 rates ContactOut 4.4/5, but the pricing opacity drags the experience down for teams trying to forecast costs.
LeadMine at a Glance
LeadMine is built for SDRs and small teams that need verified work emails on a predictable budget. Pricing is straightforward: Free at $0 with 10 credits/mo, Basic at $29 with 250 credits/mo, Essential at $99 with 1,000 credits/mo. One credit equals one prospect with a valid corporate email, one email lookup, or one verification. Duplicates within a billing period don't cost extra.
The bounce-credit refund policy is a real edge. If a verified email bounces, you get the credit back. That's rare in this space and shows confidence in their data.
Skip this if you need phone numbers or a massive database. LeadMine's 200M+ business contacts is respectable but a fraction of ContactOut's reach. Phone coverage is essentially nonexistent, and CRM integrations are thin - G2 lists just one integration. Reviews run positive (4.3/5 on G2 with 52 reviews, 4.6/5 on Capterra with 36), though some Capterra reviewers note emails still bounce despite the accuracy claims.
ContactOut caps your exports. LeadMine skips phone numbers entirely. Prospeo gives you 143M+ verified emails at 98% accuracy and 125M+ verified mobiles with a 30% pickup rate - no fair-use caps, no pricing shell games.
Stop choosing between emails and phone numbers. Get both for $0.01/email.
Pricing and Features Compared
Pricing by Tier
| ContactOut Free | ContactOut Email+Phone | LeadMine Free | LeadMine Essential | |
|---|---|---|---|---|
| Price/mo | $0 | $99/mo (billed annually) | $0 | $99 |
| Email credits | 5 emails/day | 2,000/mo | 10/mo | 1,000/mo |
| Phone credits | 5 phones/day | 1,000/mo | - | - |
| Exports | 5 exports/day | 600/mo | Unlimited | Unlimited |
| Cost/email | - | ~$0.033 per credit (at full cap) | - | $0.099 |
ContactOut's mid-tier Email plan runs $49/mo billed annually for 2,000 emails/month without phone numbers, bringing cost per email down to ~$0.025 at full utilization. But that math only works if you burn through all 2,000 credits every month. If you're pulling 500 emails/month, LeadMine's Basic plan at $29 is the smarter buy.
Also note that ContactOut caps exports at 300-600/month even on paid plans. LeadMine has no export limits, which matters when you're building lists at scale. If you're doing this at volume, it helps to understand your broader lead generation workflow and where enrichment fits.

Accuracy and Deliverability
LeadMine claims 99% accuracy and guarantees 95%+ deliverability. Their verification runs syntax checks, MX record lookups, and SMTP pings against a 200 million email database. The bounce-credit refund backs it up: if they're wrong, you don't pay. That said, some Capterra reviews mention bounces despite the guarantee, so treat 99% as a ceiling, not a floor.
ContactOut doesn't publish a universal accuracy benchmark on its pricing page, though it does promote 95%+ deliverability in core regions in its own benchmarking content. We've seen this pattern repeatedly with large-database tools - they prioritize coverage over verification depth. When you're pulling from 700M+ profiles, some percentage of that data is inevitably stale.
Here's the thing: neither tool publishes an independent, third-party accuracy benchmark, and that should bother you. Before committing, send to 200 contacts in your ICP, measure valid/invalid/not-found rates, and compare cost per valid email. The sticker price means nothing if 15% of your list bounces. If you want a deeper baseline, start with email deliverability and track your email bounce rate over time.
Who Should Pick Which
Pick ContactOut if you're a recruiter who needs the widest possible candidate pool, phone numbers matter and you'll use 500+ per month, or you're comfortable negotiating pricing directly with their sales team.
Pick LeadMine if you only need verified work emails, budget predictability matters more than database size, or the bounce-credit refund gives you peace of mind on a tight margin.
Pick neither if you need both verified emails and mobile numbers with transparent pricing. Fair-use caps and pricing confusion aren't risks worth managing when better options exist. If you're evaluating more options, compare against other email finder tools and broader SDR tools.
When Both Fall Short
We ran into this exact frustration testing both tools for a client campaign last quarter. ContactOut had the reach but the pricing felt like a shell game, and LeadMine's phone coverage was a non-starter for a team that needed direct dials. The consensus on r/sales threads tends to echo this - people want one platform that handles both data types without surprises.
Real results back this up: Snyk's team of 50 AEs cut bounce rates from 35-40% down to under 5% after switching, and AE-sourced pipeline jumped 180%. For anyone weighing ContactOut vs LeadMine and finding both lacking, it's worth a free test before signing an annual contract with either. If you're building lists from multiple sources, data enrichment services can also help close gaps.
Neither ContactOut nor LeadMine publishes independent accuracy benchmarks. Prospeo's 5-step verification delivers 98% email accuracy on a 7-day refresh cycle - 6x faster than the industry average. Snyk's 50 AEs dropped bounce rates from 35% to under 5% and grew pipeline 180%.

FAQ
Is LeadMine's bounce-credit refund real?
Yes. LeadMine refunds credits when a verified email bounces, which most email finders don't offer. The policy is documented on their Email Verifier page and is one of their strongest differentiators against ContactOut and other tools that charge regardless of data quality.
Why does ContactOut's pricing differ across websites?
ContactOut doesn't publish fully transparent pricing. Third-party sources report conflicting numbers - $49 vs $99 for what appears to be the same tier. Always verify directly with their sales team before committing to an annual contract.
Is there a tool with both verified emails and mobile numbers?
Prospeo offers 143M+ verified emails at 98% accuracy and 125M+ verified mobile numbers on a single self-serve platform. The free tier includes 75 emails and 100 Chrome extension credits per month with no annual commitment, so you can test both data types before paying. If you're also tightening outbound performance, use proven sales prospecting techniques and keep your email velocity within safe limits.
