Verification & data quality

The 3 tiers of a B2B lead (and which one you need)

A B2B lead can come in three enrichment tiers — ICP-Segmented, Enriched + Verified, and Premium/Specialized — each with more data and more verification than the last, and a price that rises accordingly.

A B2B lead can come in three enrichment tiers — ICP-Segmented, Enriched + Verified, and Premium/Specialized — each with more data and more verification than the last, and a price that rises accordingly.

Tier 1 — ICP-Segmented

The base tier: contact data that meets the defined filters — location, company size, job title. It's the right starting point when what you need is volume for a long-term nurture campaign, not immediate contact.

Tier 2 — Enriched + Verified

Adds to the previous tier: identified decision-maker, confirmed title, professional email, phone number, LinkedIn profile — plus one-by-one verification of email and phone. It's the tier most sales teams end up using, because it balances data quality with cost.

Tier 3 — Premium/Specialized

Everything in Tier 2, plus additional hard-to-find signals: recent hiring, office expansion, new licenses — the kind of information that signals a company is in an active buying moment, not just a fit for the profile.

How do you pick the right tier?

It isn't unusual to combine tiers within the same strategy: Tier 1 for nurture volume, Tier 3 for the short list of highest-value accounts worth the extra cost per contact.

Frequently asked questions

Is Tier 3 always the best option?

Not necessarily — if your strategy depends more on volume than on intent signals, Tier 1 or 2 may perform better for the same budget.

Can I request a block with mixed tiers?

Yes, it's common practice: different tiers for different segments within the same list.

FREQUENTLY ASKED QUESTIONS

Questions, answered directly.

Clear terms around exclusivity, verification, delivery, and sourcing.

What is an exclusive B2B lead?

An exclusive B2B lead is a business contact licensed to a single buyer within a given territory and vertical — it's never resold to a direct competitor during the agreed exclusivity period. Unlike a shared lead, sold to several buyers at once (the model most self-serve platforms use), an exclusive lead has a single owner. That changes the whole outreach dynamic: no race against three other companies dialing the same number the same day.

How much does it cost to verify a B2B lead?

It's billed per verification attempt, not per successful match — and since not every attempt turns up a valid, reachable contact, the effective cost of a lead you can actually use runs meaningfully higher than the attempt rate alone.

What is the difference between a shared lead and an exclusive lead?

A shared lead is sold to several buyers at once. An exclusive lead is licensed to just one — and that single fact consistently changes the price. In industries where this pattern has been documented in more detail (insurance, mortgages, roofing), an exclusive lead consistently costs 2 to 3 times more than the same lead sold as shared. It isn't an arbitrary markup — it's what it's worth to remove the race against other buyers for the same contact.

What does it mean for a lead to be "verified"?

That, before delivery, the email was confirmed to exist and the phone number was confirmed active — a real check, not a syntax validation. One-by-one verification happens lead by lead, not by sampling the batch. It's the difference between "95% of this list probably works" and "every contact on this list was confirmed before it was delivered to you."

How long does delivery of a B2B lead list take?

3 business days from when the search criteria are confirmed — ICP, volume, and enrichment tier. For recurring supply, delivery becomes a fixed cadence agreed in advance: weekly, biweekly, or monthly, matched to the buyer's consumption pace.

What is the Verified Call tier?

It's the classification given to a lead when it has a documented basis for phone or SMS contact, not just email. It differs from the Prospecting tier, which is suitable for email or LinkedIn but not for calling. The distinction exists because not every contact record is equally fit for every channel — mixing the two up is the most common way an outreach team gets into trouble without realizing it.

How much do Apollo, ZoomInfo, and Lusha charge for a verified contact?

Between $0.25 and $1.00 per contact with phone, depending on the platform — and in none of the three cases is the data exclusive. *On top of a reference annual subscription of US$15,000–45,000. Data from all three platforms can be available, at the same time, to every other subscriber — which is why two competing companies sometimes end up calling the same prospect the same week.

How is the price of a B2B lead block calculated?

It depends on three variables: the data's enrichment tier, the block's volume, and whether it's a one-time purchase or recurring supply. Enrichment tier: higher enrichment and verification means a higher price per lead. Volume: large blocks (10,000 leads or more) get a volume discount. Recurrence: contracting recurring supply instead of a one-time block earns an additional discount.

Can I test lead quality before buying a block?

Yes — a free trial sample of 100 to 200 leads, at the same filtering and verification standard as a real block. It isn't a scaled-down demo or a lower-quality sample meant to hook you — it's exactly the same standard a paying client would receive, so the purchase decision gets made on real data, not on anyone's word.

Where does the B2B contact data come from?

From public, lawfully accessible sources, processed with artificial intelligence for filtering and segmentation, and manually verified before delivery. No platform whose terms of service expressly prohibit resale of their data is used as a source. All figures in this article are either our own operating data or public pricing research on each platform mentioned, current as of publication. Third-party prices can change without notice — verify directly with each provider before deciding.
