Ampliz vs WarpLeads: Which B2B Database Actually Fits Your Outbound?
One tool sells healthcare data on a credit system. The other sells "unlimited exports" for $99/month and dares you to find the catch. The Ampliz vs WarpLeads decision comes down to specialization versus volume - and picking wrong tanks your deliverability faster than it drains your budget.
There aren't many direct head-to-head comparisons of these two tools on the web, so let's make this one count.
30-Second Verdict
Choose Ampliz if you sell into healthcare providers or need APAC-specific intelligence and credit-based economics match your volume.
Choose WarpLeads if you need high-volume list pulls at rock-bottom cost and you already have a verification workflow ready to clean every export.

Pricing and Hidden Costs
WarpLeads' headline: $99/month for unlimited exports. Their FAQ explicitly says the Unlimited plan has "no limits" and you can export unlimited leads. The free tier gives 30 contacts per month - enough to kick the tires, not enough to evaluate seriously.
If you're still mapping your outbound stack, it helps to compare other outbound lead generation tools and sales prospecting techniques before you lock into a pricing model.
Threads on r/coldemail regularly question whether "$99 unlimited" has a hidden catch. The answer is nuanced. WarpLeads also sells export add-ons for teams needing dedicated allocation - 5,000 exports for $40/month up to 1,000,000 for $2,800/month. That's a wide range, and the right tier depends entirely on your list-building cadence.
The API is where costs jump. You need an active Unlimited subscription plus quarterly-billed API access starting at $897 upfront. Unused API credits don't roll over, and there are no refunds.
Ampliz runs a credit model: free tier gets 10 credits, $50/month buys 100 credits, and the annual plan drops to roughly $480/year. Credit-based models work better for teams with tight ICPs who don't need to pull thousands of records just to find 200 good ones (use an ideal customer profile to keep pulls tight).
Tired of choosing between Ampliz's niche focus and WarpLeads' unverified volume? Prospeo gives you 300M+ profiles with 98% email accuracy and built-in 5-step verification - no external cleaning required. At $0.01/email, you spend less than WarpLeads' hidden verification costs.
Skip the export-then-verify workflow entirely. Start with 75 free emails.
Data Quality and Deliverability
Here's the thing about WarpLeads: they claim "80M+ verified leads," but Salesforge's own documentation explicitly recommends verifying emails with a third-party tool before sending. That's a telling signal from a partner integration.
If you're trying to protect inbox placement, you should also understand email deliverability basics and track your email bounce rate as you test any new data source.
Reddit sentiment is split. One user on r/Emailmarketing called the quality "terrible" - high bounce rates even after running records through Apollo's verification. But a 90-day A/B test on r/coldemail told a different story: 9% bounce, 7.1% reply rate, $22 cost per qualified lead. The poster's edge? Over-pulling and filtering aggressively before sending.
The variance is the point. WarpLeads results depend entirely on how tightly you filter and how rigorously you verify.
Ampliz carries a 4.2/5 on G2 with stronger marks for its healthcare workflows - especially NPI lookup and provider/facility-style targeting. There's less independent chatter about Ampliz's general B2B accuracy, so trial it against your own ICP before committing.
Our take: If your average deal size sits below $15k and you're not selling into healthcare, neither of these tools is your best option. You'll spend more time cleaning data than closing deals (especially if you don't have solid data enrichment services in place).
Phones, API, and Automation
WarpLeads phone coverage sits at roughly 10% of records. If direct dials drive your outbound motion, that's not a phone-first solution (you may need a tighter cold calling system to make low coverage workable).
WarpLeads does offer a Chrome extension for discovering publicly available email addresses and phone numbers on websites and professional profiles - useful for one-off lookups, less so for building call lists at scale. Their API rate limits cap at 300 requests/min, 800/hour, and 4,000/day, with credits resetting monthly and no rollover. We've seen teams burn more on WarpLeads verification costs than they saved on the unlimited plan itself, so factor that into your real cost-per-lead math.
Ampliz's SalesBuddy extension pulls company and contact data from prospect websites, and its NPI lookup is genuinely useful for healthcare sales teams. API access is available on paid plans, though the documentation is thinner than what you'd get from larger providers.
When Neither Tool Fits
If comparing Ampliz vs WarpLeads feels like choosing between niche coverage and unverified volume, there's a third path.
The 5-step verification process includes catch-all handling, spam-trap removal, and honeypot filtering, which means you skip the entire "export then verify externally" workflow that WarpLeads requires. For teams that need intent data, Prospeo tracks 15,000 topics via Bombora, letting you layer buyer signals on top of firmographic filters (see how to implement firmographic filters and intent based segmentation). In our experience, that combination of fresh data and built-in verification is what separates tools you can actually send from and tools you have to babysit.
WarpLeads covers ~10% of records with phones. Ampliz barely emphasizes mobiles. Prospeo delivers 125M+ verified mobile numbers with a 30% pickup rate - plus 15,000 intent topics so you call buyers who are actually in-market. Data refreshes every 7 days, not 6 weeks.
Cold calling works when 30% of your dials actually connect.
FAQ
Is WarpLeads really unlimited?
The $99/month plan has "no limits" per the plan FAQ. But "unlimited" doesn't mean "verified." Budget $30-50/month for third-party email verification on every batch, or expect bounce rates above 15% that damage your sender reputation.
Does Ampliz only work for healthcare?
No. Ampliz has general B2B data and APAC intelligence. But healthcare is its strongest differentiator with NPI lookup and provider targeting. For general B2B prospecting outside healthcare, tools like Prospeo or Apollo offer broader coverage and more search filters.
What if I need verified mobiles, not just emails?
WarpLeads has phones on roughly 10% of records. Ampliz doesn't emphasize mobile coverage. Prospeo offers 125M+ verified mobile numbers with a 30% pickup rate - the threshold where cold calling becomes a viable channel, not a time sink.
