What does a qualified B2B lead cost? Clay, Apollo and ZoomInfo compared

A raw contact record and a researched prospect are not the same product. A work email can be inexpensive when it comes from a large prepaid database, while a contact-ready prospect also needs a company that matches the brief, a relevant person in a current role, a usable professional email and evidence a human can review. Compare prices only after defining which of those checks the result must pass.

Define the lead before comparing cost

In this comparison, a raw contact is a person and an available work email. A contact-ready prospect adds an ICP-matched company, a relevant current role, email-verification evidence and source-backed company qualification. Asales-qualified lead goes further: need, authority, budget and timing have been established through engagement or another credible buying process.

Public data can support the first two definitions; it cannot establish the third by itself. A company-news item, job change or public post may be a useful signal, but it is not proof of purchase intent. This article therefore compares contact-ready prospect costs and keeps commercially qualified leads outside the claim.

Compare the same outcome

These figures describe pricing mechanics, not an accuracy ranking. Coverage, freshness, geographic strength, direct-dial availability, intent data and workflow features differ. A cheap unusable row is expensive; a higher-cost record can be worthwhile when its evidence prevents wasted research or outreach.

Clay starts near $0.10 for an email alone

Clay separates marketplace data from platform activity. Its current pricing page says Data Credits start at $0.05 and Actions start below $0.01. Clay’s credit guidancegives two credits as the example price for finding an email through several common providers. That makes the email alone about $0.10 at the starting credit price, before company data, web research or additional workflow actions.

Clay’s documentation says data enrichments can consume 0.5–10 or more credits, depending on the field and supplier. Combining a two-credit email with another enrichment therefore produces a broad starting range of approximately $0.13–$0.60, plus Actions and any further provider waterfall or AI work. Clay can be cheaper at scale or when customers bring their own provider keys, but the external provider bill still exists.

Apollo is cheapest when its subscription is fully used

Apollo’s current annual pricing lists 30,000 credits per seat for its $49-per-month Basic plan. Fully using that allowance implies about $0.0196 per credit. Apollo says an email consumes no more than one credit and charges only when it can verify the address, so its raw verified-email economics are difficult for usage-based research workflows to beat.

Apollo also states that data enrichment can consume up to eight credits per record. At the fully used Basic-plan rate, one email plus eight enrichment credits is about $0.18, or approximately $0.20 with one additional AI-research credit. The comparison changes at low utilisation: a team producing only 100 contacts in a month is still paying the $49 subscription, an effective $0.49 per contact before assigning value to Apollo’s sequencing, CRM, dialling and other included features.

Apollo’s standard-plan terms also matter to platforms. Its pricing FAQ says the displayed plans are for internal business use and cannot power an external customer product or resell Apollo data without a separate agreement.

ZoomInfo prices enterprise access, not one-off research

ZoomInfo does not publish a public rate card. Its public filings describe subscriptions priced by functionality, users and records under management, so a defensible unit cost requires the customer’s quote and export allowance. Any public per-contact figure is therefore an estimate rather than an official ZoomInfo price.

One current third-party pricing benchmark, verified in July 2026, estimates $3,000 per year for 2,000 Basic exports and $14,995 for 5,000 Professional exports. Full use would be about $1.50 and $3.00 per exported contact respectively. Unused credits, seats, international data and intent or AI add-ons raise the effective cost; deeper firmographics, org charts, direct dials and intent signals also make ZoomInfo a broader enterprise product than the bounded workflow compared here.

Utilisation changes the real cost

Subscription unit economics assume the customer consumes the allowance. Divide the annual contract by successful, usable outputs rather than advertised credits: unused credits, duplicates, wrong roles, stale addresses and records that fail the ICP still cost money. Usage-based execution has the opposite trade-off. Its marginal rate may be higher than a fully used database subscription, but it carries no seat minimum or unused annual capacity.

The practical break-even point depends on volume and the surrounding workflow. Apollo is compelling for a sales team continuously searching, sequencing and exporting. Clay earns its platform cost when a team needs configurable waterfalls and GTM automation. ZoomInfo targets organisations that value broad enterprise intelligence and can use it across many sellers. A small team asking an agent for a handful of researched prospects has a different cost structure.

Scrollport produced five contact-ready prospects for $0.4272

Scrollport’s Qualified Accounts to Contact Skill starts with bounded company search, selects relevant people and work emails, verifies uncertain addresses and checks only the public company evidence needed for the brief. Its five-row clean-path plan was $0.4875, or $0.0975 per accepted prospect including shared discovery.

The recorded public-data rehearsal accepted five UK B2B agency prospects for $0.4272, equivalent to $0.08544 each. That total includes research used to reject two weak matches and recover one trading-name check. Every accepted row had sourced company-fit evidence, a relevant current senior person, a valid professional work email and an active official UK identity. The selected emails already had current valid status, so no separate verifier calls were required. The exact runs, rejections and settled costs are retained in the public verification record.

Five prospects and $0.50 are the verified starter, not the Skill’s product ceiling. The caller chooses a target and maximum spend, and larger requests run in resumable, globally deduplicated batches. At the same inspected prices, 100 clean-path rows plus two discovery calls have a $9.66 base plan. A $10 ceiling is therefore a plausible target, not a promise of 100 accepted prospects: rejected candidates, missing contacts and recovery calls consume the same approved budget.

The expensive global firmographic enrichment step is deliberately optional. Public search, bounded page extraction and an appropriate official registry can usually establish the identity, status and material fit facts needed for this narrow result. A deeper enrichment call remains useful when funding, headcount or other structured fields materially determine acceptance, but it should not be purchased for every row by default.

This is verified workflow evidence, not customer proof. The rehearsal used public synthetic criteria and demonstrates that the route can produce the defined outcome within the cap; it does not establish reply quality, customer demand or sales qualification. The Skill remains explicitly customer-unproven until a customer completes it and permits that proof to be recorded.

Choose the commercial model that fits

• Choose Apollo for high-volume prospecting inside an integrated sales database and engagement suite.
• Choose Clay for configurable data waterfalls, enrichment tables and GTM workflow automation.
• Choose ZoomInfo when enterprise coverage, direct dials, org intelligence and intent justify an annual contract.
• Choose a usage-based agent workflow for small, irregular batches where a reviewed outcome matters more than owning another database interface.

The Scrollport proposition is not “the cheapest email.” It is a small, source-backed answer to a business question without a new seat, annual data allowance or manual table workflow. The adjacent verified B2B lead-list guide explains the complete evidence process.

Method and limitations

Prices were checked on 28 August 2026 against Clay and Apollo’s official pricing and credit documentation. ZoomInfo publishes no rate card, so its figures are explicitly labelled as third-party estimates. Calculations assume annual paid-plan prices, complete credit utilisation and one accepted record per charged unit unless stated otherwise. The Scrollport figure is settled rehearsal spend divided by five accepted prospects; its planned maximum is the current worst-case five-row route divided by five.

An AI agent researched current sources, normalised the credit arithmetic and drafted the first comparison from a human-supplied question and agreed output definition. Scrollport supplied the qualification boundary, rejected the phrase “fully qualified lead” and retained editorial approval over every claim. Prices and product rules can change; check the linked sources and run a representative accuracy test before purchasing any platform.
