The B2B Contact Data Pricing Index: Cost Per 1,000 Verified Emails

B2B contact data costs between $19.60 and $582.35 per 1,000 verified email addresses, a 29.7x spread for the same nominal unit. Cleanlist built that range on August 7, 2026 by fetching 21 vendor pricing pages first-hand and normalizing every published price to one denominator: 1,000 verified business email addresses, exportable, on the cheapest plan you can buy without talking to a salesperson. Only 8 of the 16 contact data vendors surveyed, 50%, publish enough information to compute that number at all. Three of them publish no purchasable dollar price at any tier. Every calculation below is shown in full.

Last updated: August 7, 2026. Every price on this page was read off the vendor's own pricing page on that date. Prices in this category move constantly, and several vendors were running promotions on the day of capture. Treat every figure as a dated observation, not a permanent rate card, and re-check the linked page before you sign anything. This index is maintained rather than republished: when a vendor changes a price, the row and the verification date change here.

How much does B2B contact data cost?

B2B contact data costs $19.60 to $582.35 per 1,000 verified email addresses among the vendors that publish enough to compute the number. That is a 29.7x range for what every vendor in it describes as the same thing: one verified business email address you can export. The table below normalizes each vendor's cheapest publicly purchasable plan to that single denominator and shows the arithmetic in full, so any row can be re-checked against the linked pricing page in about a minute. Rows are sorted by unit price. Cleanlist's own rows are computed by the same method and are marked, because a pricing study that exempts its author from its own arithmetic is not worth reading.

Two caveats belong with that table. Kaspr sells "Unlimited B2B email credits" and then caps the plan with "Up to 12,000 exports per year" on Starter and "Up to 30,000 exports per year" on Business, so the export cap is the only quantity that actually prices the plan, and that is what the arithmetic uses. Kaspr's page also carries a billing toggle showing both $49 and $65 for Starter, and the annual-versus-monthly mapping above was inferred from the page's parallel "credits per month" and "credits per year" columns rather than read verbatim, so re-verify the toggle before quoting it. Snov.io's single credit covers either saving a prospect or running a verification, so a find-then-verify cycle inside Snov.io consumes two credits, which doubles that row to $58.50 per 1,000 on annual billing.

What is a fair price per verified email in 2026?

There is no single fair price, but there is a published middle. Across the eight vendors that can be normalized from published information alone, the median of each vendor's own cheapest normalized figure is $89.29 per 1,000 verified emails. The sorted list is 19.60, 29.25, 75.00, 84.95, 93.63, 224.00, 266.67, 372.50, and the median is the midpoint of 84.95 and 93.63. One qualifier on that median: the $93.63 figure is Lusha's sale price as displayed on August 7, 2026, and Lusha's list-price equivalent is $124.75, which would move the median to $104.94. So the honest answer to "what is fair" is that anything between roughly $20 and $125 per 1,000 verified emails is inside the published band at entry volume, and anything above about $250 per 1,000 is at the expensive end of what vendors publish. Below $30 is achievable, and only two vendors publish it.

What does Cleanlist cost per 1,000 verified emails, by this same method?

Cleanlist Starter costs $52.67 per 1,000 verified emails on monthly billing and $39.33 on annual billing, computed exactly the same way as every other row. The inputs come from cleanlist.ai/pricing: Starter is $79 per month for 1,500 credits, $59 per month billed annually, and one credit buys one verified email. So 79 ÷ 1,500 × 1,000 = $52.67, and 59 ÷ 1,500 × 1,000 = $39.33. Higher tiers use the same arithmetic: Pro is $229 for 5,000 credits (229 ÷ 5,000 × 1,000 = $45.80 monthly, $172 annual gives $34.40), and Scale is $599 for 15,000 credits (599 ÷ 15,000 × 1,000 = $39.93 monthly, $449 annual gives $29.93).

Cleanlist is not the cheapest vendor in this index. Apollo Basic on annual billing is $19.60 per 1,000 at its published 1-credit reveal rate, Snov.io Starter on annual billing is $29.25, and Kaspr's export-capped Business plan works out to $31.60. All three sit below Cleanlist Starter at either billing frequency. What the Cleanlist row does show is that the number can be computed at all, which is true of fewer than half the vendors surveyed. Through August 31, 2026 there is also a promotional rate: the code 33FOREVER takes 33% off for life for new customers, so 79 × 0.67 = $52.93 per month, which is 52.93 ÷ 1,500 × 1,000 = $35.29 per 1,000 verified emails. That is a promotion with an end date, not a rate card, and it is recorded here the same way Lusha's sale price is.

How many B2B contact data vendors publish a comparable price?

Eight of sixteen, or 50%. That is the single most useful number in this index. Three vendors publish no purchasable dollar price at any tier at all, and five more publish a price and a credit allowance while withholding the conversion rate between credits and a verified email, which is the one piece of information that makes the price comparable to anything. By contrast, every email verification vendor surveyed publishes a per-unit price you can divide without asking anyone. The contrast is stark: 100% of verification vendors publish a per-unit price, and 50% of contact data vendors publish enough to compute one.

What did each vendor's pricing page actually say on August 7, 2026?

Every row below was read off the linked page on August 7, 2026, with a browser user agent for server-rendered pages and a headless Chromium session for pages that render pricing tables, sliders or billing toggles in JavaScript. Where a page had a monthly and annual toggle, the toggle was clicked and the re-rendered price recorded. Nothing here is quoted from a third-party roundup. "Not published" means the page carried no dollar figure for that tier, not that a price does not exist.

Why won't ZoomInfo publish a price?

ZoomInfo publishes no price on zoominfo.com/pricing, and on August 7, 2026 that URL did not return a readable page to any automated client we tried. Four independent attempts, all on that date: curl with a standard Chrome user agent returned HTTP 403, curl with a Googlebot user agent returned HTTP 403, an automated fetch tool returned HTTP 403, and a real headless Chromium session rendered only a challenge reading "Press and Hold to confirm you are a human (and not a bot)". Zero prices were obtainable. That is a reproducible observation on a specific date, and anyone can repeat it in under a minute.

Two things are worth saying alongside it. Gating price behind a sales conversation is a normal enterprise motion and many buyers get a quote without difficulty in an ordinary browser session, so this is a statement about what is machine-readable, not a claim that ZoomInfo refuses to quote. And ZoomInfo's finances are public: the company trades as NASDAQ: GTM and reported GAAP revenue of $310.4 million for Q2 2026 in its Form 8-K exhibit filed August 5, 2026. This index prints no ZoomInfo dollar figure at all, because we could not obtain one first-hand and we do not restate secondhand price rumors as fact.

What does Apollo actually cost per verified email?

Apollo Basic costs $19.60 per 1,000 verified emails on annual billing at Apollo's published 1-credit reveal rate, or $39.20 at the 2-credit bulk-enrichment rate the same page publishes. Apollo is the volume leader in self-serve B2B data and it is one of the few vendors here that publishes everything the calculation needs, so it is worth showing in full. As of August 7, 2026 Apollo's pricing page lists Basic at $49 per seat per month on annual billing ($65 monthly) with "30,000 credits per seat per year", Professional at $79 annual ($99 monthly) with 48,000 credits, and Organization at $119 annual with 72,000 credits and a published "min 3 seats". (49 x 12) / 30,000 gives $0.0196 per credit. At 1 credit per email reveal that is $19.60 per 1,000, and at the 2-credit bulk-enrichment rate it is $39.20.

The credit ladder is not in the plan table, which is why it is easy to miss and why most comparison articles get Apollo wrong. It sits in the enrichment calculator further down the same page, under "How enrichment credits work", and reads verbatim: "Email: 2 credits per record (enrichment + waterfall verification), ~88% match rate" and "Phone numbers: 8 credits per contact, ~81% match rate", with company records at 1 credit.

Apollo publishes two different email rates on the same page and the difference matters. Its credits table prices "Email / 1 credit / Access verified emails to connect with the right prospects" and its FAQ reads "Accessing a contact's emails uses 1 credit", which is an in-platform reveal. Its enrichment calculator separately reads "Email: 2 credits per record (enrichment + waterfall verification), ~88% match rate", which is bulk enrichment of a list you bring. Both were published on August 7, 2026. This index uses the 1-credit reveal rate, because the denominator here is a verified email you can export, and it prints the 2-credit rate alongside it. Ask Apollo which rate applies to the action you actually run. Two caveats Apollo prints alongside it belong in any budget built on these numbers. The ladder is scoped to the "Apollo database only", and Apollo notes that "if Waterfall Enrichment is enabled, additional third-party provider credits may apply", so the effective rate can be higher than 2. And the match rates are Apollo's own published figures, not an independent measurement, which matters because Apollo also notes match rates are applied to your volumes, so not every record returns a result. On that basis a phone number costs 8 credits, or $156.80 per 1,000 on Basic annual, four times the email rate.

What does a credit actually buy?

A credit buys whatever the vendor says it buys, and the definitions are not compatible with each other. Six different nouns are in use across this index for the thing you purchase (credit, export, lookup, record, action, and contact), and each of them prices a different bundle. This is the mechanical reason no normalized comparison exists in the market: there is no shared unit to compare on. The published definitions, verbatim where possible:

Worth noting plainly: LeadIQ and Cleanlist publish the same email and phone credit ladder, 1 and 10, with the difference being account enrichment at 3 credits versus company enrichment at 1. That ladder is not proprietary to either company, and readers comparing the two will find the unit definitions line up.

Why do vendors publish credits instead of prices?

A credit is a unit the vendor defines, which means the vendor controls the conversion between the number on the pricing page and the thing you actually want. Whatever the intent, the observable effect is consistent: a headline that looks cheap, a quantity that looks large, and no way to divide one into the other. This index found seven distinct mechanisms doing that work, every one of them on a live pricing page on August 7, 2026:

• The conversion rate is simply absent. Instantly publishes $47 and "Instantly Credits" with no definition of what one credit buys.
• The allowance is published as a range, not a number. Instantly's Growth tier grants "1500-2000 Instantly Credits Monthly", and its Hyper tier grants "10K-200K", a 20x-wide range.
• The consumption is published as a range. Explorium prices credits at "$0.04 per credit" and then says "Enrichments 1-5 Credits", so the same credit price yields anywhere from $40 to $200 per 1,000 enriched records.
• Two meters, both binding. Clay bills actions and data credits separately, and a workflow can exhaust either one first.
• The headline is not the entry price. Clay's Launch tier displays $167/mo while the fine print reads "Starts at $54/mo, expand anytime", so the advertised figure is 3.1x the actual floor.
• "Unlimited" behind a cap. Kaspr sells "Unlimited B2B email credits" and caps the plan at "Up to 12,000 exports per year". RocketReach sells unlimited emails and caps Essentials at "1,200 Exports Per Year". The unlimited number is the headline and the capped number is the one that prices the plan.
• The pricing page no longer exists. HubSpot's Breeze Intelligence pricing URL 301-redirects to a credits page, which 301-redirects again into a knowledge base article. There is no standalone pricing page for the product formerly sold as Clearbit. HubSpot also geo-localizes pricing currency, and rendered Canadian dollars with no visible USD toggle from our location, which is why this index publishes no Breeze dollar figure at all.

Is annual billing cheaper for B2B contact data?

Yes, and the published annual discounts cluster tightly between 10% and 25%. On August 7, 2026 the discounts stated on the vendors' own pages were: Snov.io "25% off for annual subscriptions", LeadIQ "Annual billing (25% off)", Cleanlist 25%, Apollo "SAVE 24%", People Data Labs "Save 20%", Smartlead "17% Savings", and Clay "Annual, Save 10%". Worked example: Snov.io Starter is $39 monthly and $29.25 annual, which moves its normalized cost from $39.00 to $29.25 per 1,000 verified emails, a 25% cut in unit price for a 12-month commitment.

The catch is that annual is not always optional. Five vendors in this index publish tiers that are annual-only: Apollo's Organization plan is marked "Annual Only" in the monthly view, UpLead Professional is annual only, LeadIQ Enterprise is "Annual plan only", People Data Labs Enterprise is annual, and Amplemarket's Startup plan is sold on an "annual term" at $600 per month. If a plan is annual-only, the discount is not a discount, it is the price.

What does a phone number cost compared to an email?

A phone number costs 5x to 10x an email at every vendor that prices them separately, and is bundled into a single unit at the vendors that sell "a contact". LeadIQ charges 10 credits per phone number against 1 for an email, which at its $15.00 annual Pro rate is (15 × 12) ÷ 2,400 × 10 × 1,000 = $750 per 1,000 mobile numbers, or $1,000 per 1,000 on monthly billing. Lusha charges 5 credits per phone, so its $49.90 monthly Starter plan works out to 49.90 ÷ 400 × 5 × 1,000 = $623.75 per 1,000 phones. Cleanlist charges 10 credits, giving 79 ÷ 1,500 × 10 × 1,000 = $526.67 per 1,000 phones on monthly Starter and $393.33 on annual.

Three other structures show up. Kaspr sells phone credits from a separate pool with published add-on packs at $91 for 250 credits ($364 per 1,000), $155 for 500 ($310 per 1,000) and $288 for 1,000 ($288 per 1,000). RocketReach gates phone behind a tier rather than a credit multiplier: Essentials is explicitly "Email Only" and phone requires Pro at $829 per year. UpLead bundles both into one credit, which is the reason its per-email figure is the highest in the index at $582.35 per 1,000: you are paying the phone price on every row whether you use the number or not. Amplemarket also splits the pools, granting 13,500 email credits and 600 phone credits per user per year at Startup.

How much does email verification cost?

Email verification costs $3.90 to $8.00 per 1,000 addresses at entry volume, and falls below $1 per 1,000 at million-scale. Verification is the one corner of this market where every vendor publishes a complete, divisible unit price, so no conversion rate is needed and no sales call is required. The table below shows three of the five verification vendors surveyed. The two that are missing are Cleanlist's own verification suppliers and are excluded on purpose, explained directly beneath.

Arithmetic, in full: MillionVerifier 39 ÷ 10,000 × 1,000 = $3.90 and 149 ÷ 100,000 × 1,000 = $1.49. Bouncer 8 ÷ 1,000 × 1,000 = $8.00 and 400 ÷ 100,000 × 1,000 = $4.00 and 2,000 ÷ 1,000,000 × 1,000 = $2.00. NeverBounce Growth 49 ÷ 10,000 × 1,000 = $4.90. The minimum cheque size is the hidden variable here: Bouncer's floor is 1,000 credits for $8 and MillionVerifier's is 10,000 for $39, so the cheapest per-unit vendor is also the one that requires the largest first purchase. Two operational details also move real cost: Bouncer states it "will never charge for duplicated email addresses within your list, nor for 'unknown' results", and NeverBounce credits expire after 12 months while the other two say credits never expire.

Why is verification so much cheaper than finding an email?

Verification is cheaper because it checks an address you already hold, while discovery has to produce one that did not exist in your file. At the cheap end the gap is 7.5x: $3.90 per 1,000 for MillionVerifier's smallest pack against $29.25 per 1,000 for the cheapest cleanly computable discovery price in this index (Snov.io Starter, annual). Against the most expensive computable discovery row, UpLead Essentials at $582.35 per 1,000, the gap is 149x. Both ends of that comparison are published prices from the same day, divided the same way.

The operations behind them are different in kind. Verification is a deterministic sequence of network checks: parse the address, resolve the domain's MX records, open an SMTP connection and read whether the server would accept mail for that mailbox. Discovery has to identify a person, match them to a current employer, and produce an address that no public page lists, which is why almost every vendor in this category buys from upstream sources and passes that cost through. The practical consequence for a buyer: if you already have addresses, do not buy them again. Run them through a verification vendor at single-digit dollars per 1,000 and spend the discovery budget only on the rows you are actually missing.

Do data credits expire?

Credit expiry is where the real cost hides, and the policies published on August 7, 2026 are all over the map. Explorium's terms state that "all credits are valid for 12 months and cannot be rolled over once expired. Packages are non refundable. Packages are not automatically renewed", which means an unused Scale package at $7,500 is a total loss at month 13. NeverBounce states "credits expire 12 months after purchase". Lusha rolls monthly credits over only "up to 2x monthly cap". Clay's rollover on paid tiers is 15% of annual credits, is "Not included" on Free, and its top-up credits are sold at a stated 30% premium.

Against that, MillionVerifier and Bouncer both state credits never expire. Cleanlist rolls unused credits over for up to three months on every plan including Free. When you compare two quotes, apply the expiry policy before the headline price: a 12-month non-rollover package that you consume 60% of has an effective unit cost 67% higher than its advertised rate, and no pricing page does that division for you.

Which plans have seat minimums or annual-only terms?

Seat minimums are published by three vendors in this index and they change the entry cheque substantially. Apollo's Organization plan states "min 3 seats", so its $119 per seat per month annual rate is a $357 per month minimum. Cognism states "5 seats included" on both Standard and Pro, with no published price for either. Amplemarket includes 2 users on Startup, 4 on Growth and 10 on Elite, so its $600 per month Startup plan is a two-seat purchase whether you need two seats or not. On the other side, Clay and Snov.io both advertise unlimited team seats, LeadIQ Pro covers "up to 5 users", and Cleanlist publishes no seat minimum on any plan with Unlimited Users listed on Free.

Annual-only tiers are the second structural constraint. Apollo Organization shows as "Annual Only" even in the monthly view, UpLead Professional is annual only, LeadIQ Enterprise is "Annual plan only", People Data Labs Enterprise is annual, and Amplemarket Startup is sold on an annual term. Every single vendor in the study, all 16 of 16, has at least one "Contact sales" or "Custom" tier. There is no vendor in this category whose full price list is public.

How big is each vendor's free tier?

Free tiers in this category run from 5 credits to 1,200 per year, and one vendor offers none at all. The exact sizes as published on August 7, 2026: Apollo 900 credits per seat per year, Clay 1,200 data credits per year, Lusha 40 credits per month, Seamless.AI 50 credits, UpLead 5 credits on a one-time 7-day trial, RocketReach 5 lookups, LeadIQ 50 credits, Kaspr 15 email plus 5 phone plus 5 direct email per month, Snov.io 50 credits renewing every 30 days, People Data Labs 100 records per month with email, phone and address data obfuscated, Explorium 100 credits valid 90 days, and Cleanlist 30 credits per month with no card. Cognism offers no free tier.

Read the fine print on two of those. People Data Labs grants 100 records a month but obfuscates the contact fields on Free, so the free tier does not return usable emails or phones. UpLead's 5 credits are one-time inside a 7-day trial rather than a recurring monthly allowance. On the verification side, MillionVerifier and Bouncer both give 100 free credits.

How do I compare two credit-based tools?

Compare them in four steps, and do all four before you look at the headline price. First, find the binding constraint. It is whichever runs out first: credits, exports, lookups, or seats. Kaspr's binding constraint is exports, not credits. RocketReach's is exports. Clay has two and either can bind. Second, get credits-per-action in writing. If the vendor will not put "one verified email costs N credits" in an email, you cannot budget, and you should treat that as the answer to a different question. Third, divide annual cash by annual units of the thing you actually need, not by the largest number on the page. Fourth, apply expiry, rollover, seat minimums and any annual-only requirement before you compare the two results.

One methodological note about this index that cuts both ways: every vendor here publishes volume tiers where the unit price falls, sometimes steeply. The index normalizes at the cheapest publicly purchasable entry plan because that is the only tier all seven computable vendors publish on comparable terms, and because several vendors' higher tiers are "Contact sales". If you are buying 20,000 emails a month, recompute against the tier that actually grants 20,000, at every vendor, using the same division shown in this article.

What should I ask a vendor before signing?

Ask these nine questions, in writing, and hold the quote until you have answers. Each one exists because this index found a live pricing page in August 2026 that left it unanswered.

1. How many credits does one verified email export cost, and how many does one mobile number cost?
2. Is the plan capped by credits, by exports, by lookups, or by seats, and which one binds first at my volume?
3. What is the price per 1,000 verified emails at my expected monthly volume, computed by you, in writing?
4. Do unused credits roll over, and if so how many, and what happens to the remainder?
5. Do credits expire, and on what date?
6. What is the minimum number of seats, and does that change at renewal?
7. Is this tier available on monthly billing, or is the annual price the only price?
8. What is the overage rate once the allowance is exhausted, and is it a premium over the plan rate?
9. Is the price I have been quoted a promotion, and what is the rate at renewal?

The last question matters more than it looks. Two vendors in this index were displaying discounted prices on the day of capture, and a price captured during a sale is a snapshot of a promotion rather than a rate card.

How was this index built, and what was excluded?

Every price was fetched first-hand on August 7, 2026 from the vendor's own pricing page. Server-rendered pages were fetched with curl using a browser user agent. Pages that render pricing in JavaScript were loaded in a headless Chromium session, and where a page carried a monthly-annual toggle or a volume slider, the control was actually operated and the re-rendered price recorded. Where a vendor embeds schema.org Offer markup, that JSON-LD was parsed directly. No figure in this article is estimated, averaged, or carried over from a previous version of this page or from any third-party roundup. Raw page captures are retained so every number can be re-checked without re-fetching.

Three categories of exclusion, all deliberate:

• ZoomInfo carries no dollar figure anywhere in this index, because none was obtainable by any of four methods on the capture date, and restating a secondhand price as fact would defeat the purpose of the exercise.
• Clay, Instantly, Explorium and Clearbit/Breeze appear in the census and in the raw capture table, and are absent from the normalized table, because each publishes a price without the conversion rate that would make it comparable. Rather than derive a number the vendor does not stand behind, this index states exactly which piece of information is missing. Apollo was initially in this group and was moved into the normalized table on review: it does publish the conversion, in the enrichment calculator rather than the plan table.
• Cleanlist's own data providers are not ranked anywhere on this page. Cleanlist runs waterfall enrichment across 15+ providers, and two of the five verification vendors in the underlying dataset are among the vendors Cleanlist buys from. They are named in the disclosure above and left out of the priced table. None of Cleanlist's enrichment providers were surveyed or fetched at all.

Can I download the data and check it myself?

Yes. The normalized table on this page is published as a CSV under Creative Commons Attribution 4.0, so you can rerun the arithmetic, disagree with a denominator, or extend it with vendors we did not survey:

• b2b-contact-data-pricing-index-2026-08.csv, 24 rows, one per vendor plan

Columns are vendor_and_plan, published_price_and_allowance, arithmetic, usd_per_1000_verified_emails, phone_included and captured_on. The arithmetic column carries the full division for every row, so nothing in this study requires you to trust our maths. Prices move, and every figure is stamped 2026-08-07. If a vendor has repriced since, the CSV is wrong and the vendor's own page is right.

FAQ

How much does 1,000 B2B email addresses cost?

Between $19.60 and $582.35 as published on August 7, 2026, depending entirely on which vendor you buy from. The cheapest cleanly computable published rate is Apollo Basic on annual billing at $19.60 per 1,000 using its published 1-credit reveal rate, followed by Snov.io Starter on annual billing at $29.25, and the most expensive is UpLead Essentials on monthly billing at $582.35 per 1,000, which bundles a mobile number into every credit. The median of the eight vendors that publish enough to compute a rate is $89.29 per 1,000. Eight of the sixteen contact data vendors surveyed cannot be placed on that scale at all, because they either publish no price or publish a price without saying how many credits one verified email costs. If you already hold the addresses and only need them checked, verification runs $3.90 to $8.00 per 1,000.

Is ZoomInfo more expensive than Apollo?

That question cannot be answered from published information, and any article that answers it confidently is estimating. ZoomInfo publishes no purchasable dollar price at any tier, and on August 7, 2026 its pricing URL returned HTTP 403 to three automated clients and a "Press and Hold" bot challenge to a headless browser, so there is no figure to compare against. Apollo, by contrast, publishes prices ($49 per seat per month on annual Basic, $65 monthly), credit allowances (30,000 credits per seat per year) and a credits-per-email conversion, so Apollo can be normalized: $19.60 per 1,000 verified emails on Basic annual at its published 1-credit reveal rate, or $39.20 at the 2-credit bulk-enrichment rate the same page publishes. ZoomInfo cannot be placed on that scale at all, so the two cannot be ranked against each other. Get both vendors to quote a price per 1,000 verified emails at your volume, in writing, and compare those.

What is the cheapest way to get 10,000 verified B2B emails?

It depends on whether you already have the addresses. If you hold 10,000 addresses and need them checked, verification is the cheap path: MillionVerifier's 10,000-credit pack is $39, which is $3.90 per 1,000, and NeverBounce and Bouncer both publish $8 per 1,000 at their entry packs. If you need to find 10,000 addresses that you do not currently have, the cheapest cleanly computable published entry rate in this index is $29.25 per 1,000, so 10,000 addresses is roughly $292.50 of credits, spread across the months a plan grants them. Before committing, recompute at your actual volume, because every vendor here publishes higher tiers where the unit price falls and the entry-tier rate is not the rate you will pay at scale.

Why do B2B data vendors hide their pricing?

Most do not hide the price so much as hide the conversion rate. Only 3 of 16 vendors surveyed publish no dollar figure at all (ZoomInfo, Cognism and Seamless.AI). Six more publish both a price and a credit allowance while omitting the one number that connects them, which is how many credits one verified email costs. The effect is that a pricing page can look completely transparent, showing a dollar amount and a large credit quantity, and still be impossible to compare against a competitor. All 16 of 16 vendors surveyed also keep at least one "Contact sales" tier, so no vendor in this category publishes a complete price list. The practical defense is to refuse to compare headline prices and to compare only price per 1,000 verified emails, computed by the vendor, in writing.
