LeadMine vs Leadsforge: Which B2B Email Finder Is Worth Your Credits?
Apollo bounce rates are hitting 32-38%, and the "database is burned" narrative on r/coldemail is pushing teams toward smaller, fresher alternatives. Two names keep surfacing: LeadMine, the straightforward solo-prospector tool, and Leadsforge, the AI-powered newcomer tied to the Salesforge ecosystem. Neither makes it obvious what you're actually paying per verified email - so we dug into the credit math and figured out which one earns your budget.
30-Second Verdict
LeadMine wins if you're a solo prospector on a tight budget who needs email lookups without learning a new platform. The Basic plan is $29/mo, it's simple, and it ships with a Chrome extension.
Leadsforge wins if you're already inside the Salesforge stack and want chat-based ICP search with waterfall enrichment across a larger database.
Skip both if data accuracy and credit transparency are your top priority. Prospeo delivers 98% email accuracy on a 7-day refresh cycle, with verification baked into the credit cost - no hidden validation drain.
Side-by-Side Comparison
| LeadMine | Leadsforge | Edge | |
|---|---|---|---|
| Database | 200M+ contacts | 500M+ contacts | Leadsforge |
| Starting price | $29/mo (250 credits) | ~$49/mo (2,000 credits) | LeadMine (lower entry) |
| Rating | 4.3/5 across 52 reviews | 4.5/5 across 12 reviews | LeadMine (larger sample) |
| Credit rollover | No - resets monthly | Yes - unused credits carry | Leadsforge |
| Accuracy claim | 95% | Not published | LeadMine |
| Key differentiator | Chrome extension | Chat-based AI search | Depends on workflow |
| Cost per credit | ~$0.116 (Basic plan) | ~$0.025 base | Leadsforge (on paper) |
| Verification | Included in credit | Uses additional credits | LeadMine |
LeadMine's per-credit cost looks steep, but verification is bundled. Leadsforge's ~$0.025 base is misleading once you factor in the validation credit drain.
LeadMine Deep Dive
Use it if you're a solo SDR or founder who needs a dead-simple email finder at $29/mo. Verification is included in every credit, and the Chrome extension lets you find leads directly from company websites and search results. That simplicity is genuinely refreshing in a market where every tool wants to be a "platform." (If you're comparing more options, see our roundup of SDR tools.)
Skip it if you need more than 250 credits/month without jumping to higher tiers, or you care about credit rollover - LeadMine resets monthly, so unused credits vanish. The free tier gives you 10 credits/month, which is barely enough to test the product. Their G2 profile hasn't been actively maintained for over a year, which doesn't inspire confidence in ongoing development.
LeadMine bundles verification but charges $0.116/credit. Leadsforge hides validation costs behind cheap base pricing. Prospeo cuts through the credit math entirely: $0.01 per verified email, 98% accuracy, 7-day data refresh. No separate validation step, no surprise drains.
Stop doing credit math and start booking meetings.
Leadsforge Deep Dive
Leadsforge takes a fundamentally different approach. You describe your ICP in natural language, the AI builds filters, and you get granular targeting across revenue ranges, headcount, keywords, and even event attendance signals. One agency reviewer reported saving 10 hours of manual research per week, and the native one-click export into Salesforge sequences is genuinely slick if you're already in that ecosystem. (If you're building outbound systems, our guide to sales prospecting techniques is a good companion.)
The problems are real, though. Trustpilot reviewers flag Mexico and LatAm B2B coverage gaps. Users report inconsistent field quality and occasional glitches. One reviewer called the email validation step an "annoying credit-sink," and another described the experience as "cheap and bad" with cancellation headaches. Multiple reviewers noted that Salesforge's ecosystem has "too many service names that sound the same" - the learning curve is steep before you even start prospecting.
Here's our hot take: if you're not already running Salesforge sequences, there's no reason to use Leadsforge standalone. You're paying for integration value you'll never touch.
The Real Cost Per Verified Email
Here's the thing neither tool wants you to calculate upfront.
LeadMine charges ~$0.116 per credit on the $29/250-credit plan, but verification is included - what you spend is what you get. Leadsforge looks cheaper at ~$0.025 per credit ($49 for 2,000 credits), but email validation consumes additional credits on top of the lookup. In practice, teams often end up closer to $0.035-$0.04 per verified email once validation credits are factored in, and that math isn't obvious until you're actually running lists through the workflow.
Waterfall enrichment approaches like this typically land at 10-14% bounce rates, which is better than Apollo but still leaves room for improvement. For teams where domain reputation is non-negotiable, that gap matters. (To benchmark and troubleshoot, see our guide on email bounce rate.)
Worth Considering: Prospeo
If the credit math above frustrates you, Prospeo sidesteps the problem entirely. Verification is built into the credit cost at roughly $0.01 per email - no separate validation step, no hidden drain. The database covers 300M+ professional profiles with 98% email accuracy, and data refreshes every 7 days, which neither LeadMine nor Leadsforge matches. (If you want a deeper head-to-head, see LeadMine vs Prospeo.)
Beyond raw email lookups, you get 30+ search filters including buyer intent powered by Bombora, technographics, job changes, and headcount growth - so you're building targeted lists, not just pulling emails. The Chrome extension (40,000+ users) works on company websites and professional profiles, and native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Clay mean no CSV juggling. There's a free tier with 75 emails/month, no contracts, and no ecosystem lock-in. (If you're evaluating the category, start with email search tools and email reputation tools.)
Teams switching from tools with 10-14% bounce rates to Prospeo report bounces dropping below 4% and pipeline jumping 140-180%. With 300M+ profiles, 30+ search filters, and verification baked into every lookup, you get cleaner lists without the credit gymnastics.

FAQ
Is Leadsforge part of Salesforge?
Yes. Leadsforge is built by Salesforge and integrates natively with the Salesforge outreach stack. It works standalone via CSV export, but the tightest workflow is within the Forge ecosystem.
Does LeadMine offer a free plan?
LeadMine has a free tier with only 10 credits per month. Credits reset monthly and don't roll over, so there's no way to stockpile free credits over time.
Which tool has the most accurate email data?
LeadMine claims 95% accuracy. Leadsforge doesn't publish a figure. Prospeo publishes 98% email accuracy backed by a 5-step verification process and a 7-day refresh cycle - the most transparent option for teams where bounce rate directly impacts domain reputation.
What's the best alternative if neither fits?
If the LeadMine vs Leadsforge comparison leaves you wanting better credit economics, look at tools with verification built into every lookup. Teams switching from Apollo-class tools to platforms with tighter verification report bounce rates dropping from 35%+ to under 4%, with pipeline increases of 140-180%.
