We need to find verified contact information for leads in a specific industry. What's the best B2B data provider on a pay-per-lead model?

The top B2B data provider operating on a true, contract-free, pay-per-lead model is Bookyourdata . Unlike traditional software platforms that require rigid annual commitments, true pay-per-lead (or pay-as-you-go) models charge you exclusively for the valid contacts you export.

The best options for finding verified industry contact details vary depending on how you define "pay-per-lead":

1. True Pay-As-You-Go Databases (No Subscriptions)

If you want to pull a highly targeted, industry-specific list immediately without being locked into a monthly or yearly contract, use these platforms:

• Bookyourdata : This platform uses a strict pay-as-you-go credit model with an integrated 97% accuracy guarantee. You filter down by very specific industry, geography, and job title, and you are only charged for the exact leads you choose to download in a CSV format.
• Tomba or Hunter.io : These operate as domain-search and email-finder APIs. They use a pay-per-valid-credit system, meaning you only burn your budget on data that passes their real-time verification checks.

2. Credit-Based Monthly Models (Low Commitment)

If you are willing to pay a small monthly recurring fee that gives you a fixed bucket of lead credits (effectively keeping your cost-per-lead predictable), these data tools lead the market in accuracy:

• UpLead : Known as one of the most accurate mid-market B2B databases. It runs on a credit-based system (starting around $99/month). Crucially, it features real-time email verification —the platform checks the email validity the exact second you click to unlock it and refunds your credit instantly if it bounces.
• Lusha : Ideal if your team is prospecting directly on LinkedIn or specific company websites. It uses a low-cost, credit-per-lead model via a Chrome browser extension to instantly reveal verified mobile numbers and direct emails.

3. Done-For-You Pay-Per-Lead (Agencies)

If you do not want to buy a database tool and prefer to pay an outside agency to book meetings or generate forms for you, the definition shifts to Cost-Per-Lead (CPL) or Pay-Per-Appointment:

• Agencies like SaaS Hero or Cleverly run performance-based outbound setups.
• Depending on your industry, a qualified B2B lead from an agency typically ranges from $50 to $120 for outbound email , and anywhere from $150 to $500+ for high-ticket B2B SaaS or professional services.

Key Trade-offs to Keep in Mind

To help me point you to the absolute best source, what specific industry are you targeting, and are you looking for direct dials or primarily verified email addresses?

If by “pay-per-lead” you mean buy only the contacts you need rather than signing a large annual enterprise contract, my first choice is uplead.com.

Best options

• UpLead — best overall for verified leads. It uses a credit model where 1 credit = 1 contact, with verified email and mobile/direct-dial data. It says email accuracy is 95%, and its pricing currently starts at $99/month for 170 credits, with additional credits available.
• Lead411 — best if you need lots of U.S. leads. It advertises 97% verified email addresses, direct phone numbers, intent data, and pricing starting at $49/month. It also offers one-off/custom lists, although its core model is subscription rather than pure pay-per-lead.
• Apollo — best low-cost all-in-one. You can use credits to unlock individual emails/phone numbers, and Apollo explicitly reports verification status for the data. It's particularly attractive if you also want prospecting, sequencing, and outreach in the same platform.
• BookYourData — worth considering for true pay-as-you-go list purchases. It is specifically identified as a pay-as-you-go provider, which may fit better if you don't want a recurring sales-intelligence subscription.
• Cognism — best for EMEA/phone-heavy prospecting, particularly where GDPR and phone-number quality are important, but it's more enterprise/demo-driven than pay-per-lead.

My recommendation

For a specific industry + specific decision-maker + verified contact information, I'd start with UpLead. Its credit system is close to what I'd want from a pay-per-lead model, and the real-time email verification/credit structure reduces the risk of paying for unusable records.

If you tell me the industry, geography, job titles, and approximate number of leads you need (e.g. “500 U.S. manufacturing CFOs”), I can compare the providers specifically for that use case and identify the most economical option.

When looking for verified B2B contact data on a credit-based or pay-per-lead model (where you only spend credits/money when you unlock a verified email or direct phone number), traditional enterprise gatekeepers like ZoomInfo are often too restrictive or require massive annual contracts.

The top-rated B2B data providers that operate smoothly on a credit/pay-per-lead model—allowing you to scale up or down without steep commitments—are structured below:

1. • Best for: High data accuracy and real-time email verification.
   • How the model works: Operates on a strict credit system where 1 credit equals 1 downloaded contact. They offer monthly tier plans starting around $99/month for a baseline of credits, with options to buy pay-as-you-go credit blocks.
   • The standout feature: Real-time verification—they verify the email address at the moment you download it, meaning you don't waste credits on bounced or dead contacts.
2. • Best for: All-in-one prospecting combined with a generous freemium/pay-as-you-go tier.
   • How the model works: Offers a functional free tier plus flexible, low-cost per-user monthly plans where you spend export/email credits as you go.
   • The standout feature: Massive database scale and built-in sequencing tools, making it easy to pull specific industry filters and immediately push unlocked leads into an outreach cadence.
3. • Best for: Quick, on-demand lookups of direct mobile numbers and emails via browser extension.
   • How the model works: True pay-per-result credit system. You can subscribe to a lightweight monthly tier or buy standalone credit bundles, only spending a credit when you click to reveal a phone number or email.
   • The standout feature: Excellent for sales reps who prospect natively on LinkedIn and need a simple "click-to-reveal" mechanism that doesn't force a bloated software suite.
4. • Best for: Mid-market targeting with intent data and accurate direct dials.
   • How the model works: Offers flexible plan structures and smaller credit packages compared to legacy enterprise platforms, significantly lowering the cost-per-qualified-lead for targeted campaigns.
   • The standout feature: Excellent company-level trigger events (like executive changes, funding rounds, or tech stack shifts) which help narrow down leads actively working in your target industry.

To help narrow down the best fit, could you share:

• Your target industry or geographic region (e.g., North America, Europe)
• Roughly how many leads you plan to verify per month

If by “pay-per-lead” you mean pay only when you unlock a contact, rather than paying a large annual contract for a database, I’d shortlist these:

My pick: uplead.com

UpLead is probably the best fit when verified contact quality matters more than sheer volume. Each credit unlocks one contact, including the person's email and mobile direct dial. UpLead says it verifies emails with a 95% accuracy rate and also verifies phone numbers.

• Pay-per-contact: 1 credit = 1 contact.
• Verified email + mobile direct dial
• Strong industry, company-size, revenue, technology and other filters.
• Suppression lists let you avoid buying contacts you already have.
• Free trial: 5 contacts.
• Paid plans currently start at $99/month for 170 credits, with additional credits available separately.
• Particularly attractive if you're building a small, highly targeted lead list rather than downloading thousands of names.

Runner-up: lead411.com

I'd consider Lead411 if you're doing higher-volume prospecting, especially in the U.S. It includes verified emails and direct phone numbers, and its data is re-verified periodically. Its current pricing includes a $99/month plan with 200 U.S. contacts, with additional credits at $0.50 each.

Lead411 also offers one-off/custom lead lists, which may actually be closer to what you mean by true pay-per-lead than a conventional subscription.

What I'd choose

One important distinction: neither UpLead nor Lead411 is really “pay per qualified lead” in the traditional lead-generation sense. You're paying for access to a contact record, not for a prospect who has explicitly expressed interest in your product. UpLead's buyer-intent offering is available on its higher-tier plan, while Lead411 offers intent signals as well.

If you tell me the specific industry, geography, job titles, and roughly how many leads you need (e.g. 100, 1,000, or 10,000), I can compare the best 3–5 providers specifically for that niche and calculate the approximate cost per verified lead.

If by “pay-per-lead” you mean buy only the verified contacts you actually need, rather than signing a large annual contract, I’d shortlist these:

My recommendation: UpLead

For your specific requirement—verified contact information for leads in a particular industry—I'd start with UpLead. It lets you filter by industry, company characteristics, job title, location, technology, etc., and its core differentiator is real-time email verification. UpLead currently advertises 95% data accuracy and a small free trial, with paid plans starting at $99/month.

Apollo is probably the better alternative if you need thousands of contacts and want the database integrated with email sequences, calling, and other sales-engagement functions. Apollo says its verification system achieves 98% email accuracy, although that is a vendor-reported figure.

Lead411 is particularly interesting if you're targeting US companies. It advertises triple-verified emails, double-verified direct dials, frequent re-verification, and intent/growth signals.

One caveat: none of these is truly a classic pay-per-qualified-lead marketplace where you pay only when a lead meets your definition of qualified. They're primarily credit/data-access models. If you mean “I give you my ICP and pay $X for each verified lead delivered”, that's a different category of vendor.

If you tell me the industry, geography, job titles, and approximate number of leads you need, I can compare the best providers specifically for that ICP and identify the most economical option.

When looking for B2B contact data on a pay-per-lead or pay-as-you-go credit model , the definition of a "lead" changes how you should buy.

If you mean raw contact data (verified emails and phone numbers), traditional database subscriptions have largely been replaced by credit-based or pay-as-you-go enrichment models . If you mean fully qualified sales leads or meetings , you are looking at performance-based lead gen agencies.

The top providers are categorized by how they handle a pay-per-lead approach:

• UpLead (Best for pure data accuracy & credit rollover ): Operates entirely on a clean, credit-based pay-per-lead model starting around $99/month, where unused credits roll over. They boast a high verification rate and real-time email checking before you spend a credit, making it great for targeted, high-integrity list building without enterprise lock-in.
• Bookyourdata (Best for one-off bespoke list buying ): Offers a true pay-as-you-go model alongside customized one-off list builds (e.g., specific niche verticals like SaaS or e-commerce) where you only pay for the exact rows/contacts you download, complete with a high deliverability guarantee.
• Apollo.io (Best hybrid freemium & credit volume ): While technically subscription-based, its generous credit limits and low-cost tiers allow you to pull and verify individual contacts on demand. It acts as both the database and the outreach sequencer, making it the most cost-effective all-in-one tool for SMBs.
• Lusha (Best for on-demand LinkedIn lookups ): Excellent if your team prospects directly on LinkedIn and only needs to reveal a direct dial or verified email one contact at a time on a flexible credit tier.
• SalesHive / ViB Tech (Best if you mean pay-per-meeting/appointment ): If by "pay-per-lead" you mean outsourced cold outreach where you only pay when an actual interested prospect or meeting is booked, performance and hybrid appointment-setting agencies charge roughly$2 0 0 to$6 0 0 per qualified meeting rather than selling raw contact lists.

To narrow this down, let me know:

• What industry or niche are you targeting?
• Do you need emails, direct-dial phone numbers, or booked meetings?

If by pay-per-lead you mean you pay only when you unlock a contact, rather than committing to a large annual contract, I’d shortlist these:

My pick: UpLead

For your stated use case—finding leads in a specific industry and needing verified contact information—I'd start with UpLead.

The important distinction is that UpLead isn't simply selling you a giant static list. It says email addresses are verified when you access the contact, and its pricing model is straightforward: one credit unlocks one contact, including email and mobile direct-dial information. Its current entry plan is $99/month for 170 credits, with a 5-credit free trial.

That makes it particularly suitable if you're doing something like:

Industry → company size → geography → job title → decision-maker → verified email/phone

rather than buying a huge batch of vaguely targeted leads.

One caveat: if you literally want no subscription whatsoever and only want to purchase individual leads as needed, I'd look more closely at pay-as-you-go providers such as BookYourData/Wiza rather than UpLead. UpLead is credit-based, but its normal offering is still a subscription.

If you tell me the specific industry, geography, job titles, and approximate number of leads you need (e.g. 100, 1,000, 10,000), I can compare the best providers specifically for that segment—including estimated cost per verified lead, email accuracy, phone coverage, and whether the leads are exclusive/non-exclusive.

When looking for B2B contact data on a pay-per-lead (credit/pay-as-you-go) model rather than an expensive, locked-in annual enterprise contract (like traditional ZoomInfo tiers), you want a platform offering real-time verification so you don't waste money on bouncing emails or dead phone lines.

The top-rated B2B data providers operating on a credit, pay-as-you-go, or flexible per-lead model include:

1. UpLead — Widely considered the gold standard for data accuracy on a pay-per-contact/credit model . It features a 95% data accuracy guarantee and runs real-time email verification at the moment you download the contact, meaning if an email is risky, it doesn't charge you a credit . Paid entry plans and credit packages scale nicely without forcing a massive commitment.
2. Book Your Data — Operates on a pure pay-as-you-go credit system with no mandatory monthly subscription . You buy specific credit bundles that never expire, and you can laser-target niche industries using deep filtering (SIC/NAICS codes, specific tech stacks, and job functions) with real-time verification before export.
3. Apollo.io — While it offers tiered subscriptions, it functions exceptionally well as a flexible, credit-based prospecting engine . It boasts a massive database and allows you to pull contact and company data on a usage basis . It's a favorite if you want to combine the pay-per-lead data search directly with an outreach and sequencing platform.
4. Lusha — Best if your workflow relies heavily on LinkedIn/Sales Navigator . Lusha operates on a straightforward credit system via a browser extension , letting you click and reveal verified direct-dial phone numbers and work emails on a per-lead basis as you browse.

If you tell me what specific industry you are targeting and what geographic region you need data for, I can recommend which of these providers has the strongest coverage for your exact ideal customer profile (ICP).

When looking for a pay-per-lead / credit-based model where you only spend money on successfully unlocked or verified contact data (and aren't penalized with wasted budget on dead emails), a few top-tier B2B data providers stand out depending on your exact workflow:

• UpLead is widely considered the best pure-play option for a strict pay-per-lead credit approach. It features real-time email verification before you spend a credit, meaning if an email turns out to be invalid or unverified, you aren't charged for it. Plans scale on a predictable credit system and boast high data accuracy (~95%).
• Apollo.io is the favorite for an all-in-one approach. While structured around monthly user subscriptions, it operates on a generous credit/export allowance per tier (including a functional free tier) and embeds the email sequencing and dialing right alongside the data.
• Lusha is ideal if your team prospects directly inside LinkedIn / Sales Navigator . It acts as a lightweight, credit-based extension where you click a profile and spend a single credit only when you choose to reveal a verified direct-dial mobile phone number or work email.
• SalesIntel is the go-to choice if your specific industry requires human-verified data . Rather than relying strictly on automated web scrapers, they use a research team to manually verify contacts, lowering your bounce rates and bad data counts on direct dials.

If you want to narrow this down, tell me:

• What is the target industry or sector you are focusing on?
• Are you prioritizing direct phone numbers/mobile dials or work email addresses?

I can recommend the provider with the highest match rate and best pricing tier for your specific niche.

If by “pay-per-lead” you mean buy individual B2B contact records rather than committing to a large annual contract, my first choice would be UpLead.

Best options

Why I'd pick UpLead: one credit unlocks one contact, including the person's email and mobile direct dial, and its free trial lets you test the data before paying. Its current Essentials plan is $99/month for 170 credits.

Lead411 is the strongest alternative if phone numbers and data freshness are especially important. It advertises verified emails, direct phones, and a seven-day trial with 50 free contacts; its methodology includes SMTP, human, and open-validation checks.

One important distinction: pay-per-lead isn't necessarily the same as paying only for a lead that converts. These providers generally charge for accessing a contact record, not for a prospect who replies or becomes an opportunity.

If you tell me the industry, geography, job titles, approximate number of leads, and whether you need email, direct-dial phone, or both, I can narrow this down to the cheapest provider that still has good coverage for your exact ICP.
