ZoomInfo vs Clearbit (2026): Full Contact Database or Enrichment Inside HubSpot
Publish date: Nov 13, 2026
ZoomInfo vs Clearbit is no longer a choice between two standalone data vendors. Clearbit sells nothing on its own now: its data fills records inside HubSpot, on a paid HubSpot seat. ZoomInfo sells a contact database with direct dials and intent signals on an annual license, at a median $33,500 a year across Vendr's buyers.
Pick Clearbit, meaning HubSpot's data enrichment, when your CRM is HubSpot. It fits leads that already carry a work email and lack company and job fields. Pick ZoomInfo when you need net-new contacts with phone numbers, buyer intent, or a database that plugs into Salesforce or Dynamics. A HubSpot team that also prospects can run both.
One more input comes from a test Spona ran itself, so read it as vendor data. The same 4,913 named contacts went to ZoomInfo and to Spona. ZoomInfo returned a verified work email for 83.1% of them and a direct dial or mobile for 64.1%. Clearbit has no column in that test, because HubSpot's enrichment needs the work email as its input and adds no contact email or phone.

ZoomInfo: a contact database on an annual license
ZoomInfo's homepage sells go-to-market data and says it serves over half the Fortune 500, a claim of its own.
Its pricing page lists three sales plans, Professional, Copilot Advanced and Copilot Enterprise, with no prices. Each export costs one credit. Buyer intent signals and website visitors start on Copilot Advanced, and Streaming Intent is an add-on.
What do buyers pay? Vendr's purchase data puts the median at $33,500 a year across 1,581 purchases. Vendr's range runs from $7,267 to $156,000, so the median covers teams of every size.
The contract matters as much as the price. ZoomInfo's posted license terms auto-renew. Unless written notice arrives at least 60 days before the term ends, the contract extends for the initial term or one year, whichever is longer. The renewal fee rises 10%, plus any discount that applied.
The terms also state that the agreement is not cancellable. Your order form sets the actual term, so read it before you sign. Our ZoomInfo pricing post walks through the renewal clause and the credit model. On CRMs, ZoomInfo's own comparison page lists Salesforce, HubSpot and Microsoft Dynamics among its integrations.
Clearbit: enrichment that comes with a HubSpot seat
Clearbit's homepage says "Clearbit has joined HubSpot!" and its only button is a customer login. HubSpot completed the acquisition on December 4, 2023. Clearbit's help center says it is "no longer offering new standalone Clearbit subscriptions". The free tools ended on April 30, 2025.
Inside HubSpot, data enrichment does not consume HubSpot Credits. It comes with Starter and up on Marketing, Sales, Service, Data and Content Hub. One way in is Sales Hub Starter, listed at $20 a seat a month before new-customer discounts.
HubSpot describes the data as its own commercial dataset, third-party providers and public information. It claims over 200 million company and buyer profiles, again its own count. For what a seat includes and which features do draw credits, read our Clearbit pricing post.
Clearbit ZoomInfo data enrichment comparison: company fields
Data enrichment means filling blanks on a record you already hold. HubSpot publishes its exact list: 14 contact and 29 company properties. ZoomInfo documents its company fields in its enrichment API guide, where a domain is enough to return a match.
How full are such fields in practice? Spona's own records give one measure.
The table shows the share of company records with each field filled, on one stratified sample per country: 27,613 US companies and 13,487 UK companies. Every field uses the same denominator, and a field counts only when it is nonblank and valid. The same company appears in all 16 checks, so never add the rows together.
| Field | Spona US | Spona UK | HubSpot enrichment property | ZoomInfo documents it |
| Company name | 99.6% | 99.8% | Company name | Yes |
| Website/domain | 98.8% | 98.3% | Company domain name; Website URL | Yes |
| HQ country | 99.7% | 99.9% | Country/Region | Yes |
| HQ city | 98.8% | 98.3% | City | Yes |
| HQ street address | 96.8% | 96.8% | Street Address | Yes |
| Postal code | 98.1% | 97.5% | Postal code | Yes |
| Industry code | 98.5% | 98.2% | Industry; Industry group | NAICS and SIC |
| Employee band | 96.8% | 97.3% | Employee range; Number of employees | Yes |
| Estimated revenue band | 93.4% | 93.6% | Revenue range; Annual revenue | Yes |
| Founded year | 95.9% | 95.8% | Year founded | Yes |
| Company phone | 95.6% | 95.3% | Phone number | Not on the pages we checked |
| Company LinkedIn URL | 96.8% | 96.5% | LinkedIn company page | Yes |
| Business description | 98.1% | 98.5% | Description | Yes |
| Operating status | 99.3% | 99.5% | No property | Company status, certified |
| Legal entity identifier | 94.5% | 94.8% | No property | Not on the pages we checked |
| Technology profile | 90.7% | 91.2% | Web Technologies | Yes, as a separate call |
Two readings to avoid. A fill rate measures completeness, not accuracy: a filled technology profile means the record holds one, not that the company runs Salesforce. And "not on the pages we checked" means ZoomInfo's enrichment pages linked here do not list the field, not that ZoomInfo lacks it.
The contact side is where the two products part. HubSpot's 14 contact properties cover city, state, country, job title, seniority, role, sub role and LinkedIn URL, plus two opt-out fields. No email, no phone, no mobile. ZoomInfo says its enrichment returns verified business emails, direct dials and mobiles; its developer docs name the fields emailAddress, directPhone, mobilePhone, jobTitle and managementLevel.
The inputs differ too. HubSpot needs a first name, last name and work email for a contact, or a domain for a company. ZoomInfo takes an email, a domain or a LinkedIn URL.
HubSpot's enrichment runs in three modes. By hand, you enrich up to 100 records at a time from an index page. Automatic enrichment fills blanks only. Continuous enrichment stops updating a property once someone edits it.
The firmographic data it fills suits inbound leads: the record exists, the email is there, and the blanks are company fields.
ZoomInfo emails and phones: a same-sample test
Field lists say what a vendor can return. A test on the same names shows what each returned on one sample. Spona sent the same 4,913 named contacts to ZoomInfo's SalesOS package and to its own Targeted Search.
The sample holds 2,183 US and 1,071 UK contacts. The rest sit in Germany (947) and France (712).
The sample is stratified by employee band and role. Both tools received the same names and domains on the same day. Every returned address then went through the same independent SMTP and DNS verification protocol, blind to the source.
"Returned" means passed, catch-all or invalid; "phone" means a direct dial or a mobile came back.
| Measure (4,913 contacts each) | ZoomInfo (SalesOS) | Spona (Targeted Search) |
| Work email returned | 4,417 (89.9%) | 4,837 (98.5%) |
| Passed the verifier | 4,083 (83.1%) | 4,759 (96.9%) |
| Catch-all | 231 | 49 |
| Invalid | 103 (2.3% of returned) | 29 (0.6% of returned) |
| No email returned | 496 | 76 |
| Direct dial or mobile returned | 3,149 (64.1%) | 4,381 (89.2%) |
On the same names, Spona returned 676 more verified emails and 1,232 more phone numbers. That is our arithmetic from the two columns.
Read the caveats before you quote it. Spona ran the test, so treat it as vendor data, not an independent benchmark. Only the verifier protocol was independent.
Nobody verified the phone numbers, so a returned number is a returned number, not a proven working one. A catch-all result is unknown, not good.
"Passed" means the verifier accepted the address, not that an email landed.
Why no Clearbit column? HubSpot's enrichment takes the work email as its input and returns no contact email or phone, so there is nothing to score. Its job is the other half: job title, seniority and the 29 company properties on a record that already carries a work email.
ZoomInfo flags freshness on its own records. Each contact carries an accuracy score, the "likelihood the contact is reachable and still employed", on a scale of 70 to 99. A certified company is one where ZoomInfo confirmed activity in the last 12 months. ZoomInfo also claims up to 95% first-party data accuracy, a vendor claim.
Where Spona fits, and where it does not
Spona sells contact data per field, and no annual license is required. Targeted Search, the Chrome extension in the test above, costs 13 credits for a work email and 88 for a mobile. One credit costs $0.008 to $0.01, depending on the plan.
That is about $0.10 to $0.13 an email. A mobile runs $0.70 to $0.88. The Pro plan costs $99 a month for 10,500 credits. At 13 credits each, that is about 800 work emails a month, our arithmetic.
The HubSpot integration is available. Spona also enriches a list you upload, priced per field.
Where the other two are stronger. ZoomInfo wins on buyer intent, website visitor identification and org charts: Spona has no intent product yet (Signal Search is coming soon), no visitor identification and no form shortening. Its API key is also coming soon.
HubSpot wins on firmographics for records already in HubSpot, at no credit cost, and on form shortening.
Teams that need signals, or a database to browse, need ZoomInfo. A team holding 500 names with no emails needs about 6,500 credits here, our arithmetic, which fits inside one Pro month.
What ZoomInfo and Clearbit cost a five-rep team
This is an illustration from list prices and Vendr's purchase data, our arithmetic throughout.
| Line | Price |
| HubSpot Sales Hub Starter, 5 seats, enrichment included | $1,200 a year |
| HubSpot Prospecting Agent, if you add it | $1 a lead |
| ZoomInfo license | No public price; Vendr median $33,500 a year, all deal sizes |
| ZoomInfo renewal under the posted terms | +10%: $3,350 on the median |
| Spona Pro | $99 a month for 10,500 credits |
The Vendr median comes from 1,581 purchases of every size, and the range starts at $7,267. A five-rep deal may land well under the median, but under the posted terms, the 10% uplift applies to whatever price you agree. HubSpot's seat price buys the CRM and the enrichment together; other HubSpot features do draw credits, and our Clearbit pricing post lists which. For ZoomInfo's plan tiers and credit rules, see ZoomInfo pricing.
Using ZoomInfo and Clearbit together in HubSpot
A HubSpot team that prospects has two routes to ZoomInfo data, and both leave the native enrichment running for inbound records.
The first route is ZoomInfo's own: ZoomInfo Enrich for HubSpot and the ZoomInfo HubSpot Connector. It needs a ZoomInfo license. ZoomInfo's pricing page says integrations in most cases carry a base cost and require a minimum bulk credit purchase.
The second route is HubSpot's. Its Prospecting Agent sources contacts with phone numbers, emails and job titles from providers including ZoomInfo, Apollo, Surfe and Seamless.AI, at $1 a lead. ZoomInfo's own announcement says it was selected as a third-party data provider and frames the benefit for HubSpot users with ZoomInfo accounts.
Which route? Hold a ZoomInfo license already, and the connector puts its fields on your records. Hold none, and check first. HubSpot's agent page does not say whether its ZoomInfo data needs a ZoomInfo account, and ZoomInfo's announcement says to connect ZoomInfo in HubSpot.
Read the data terms on both sides. ZoomInfo's integration terms let it use integrated data to test, develop, improve or enhance its products. Customers can change these permissions inside ZoomInfo.
HubSpot withdrew a planned terms change after customer pushback and said future enrichment contributions will be "fully and transparently opt-in". HubSpot's own page says enrichment may add only a record's first name, last name and business email address to its commercial dataset. With continuous enrichment alone, nothing is added.
ZoomInfo or Clearbit: which to choose by stack
Start from the CRM and the field you lack, not from the brand.
HubSpot on a paid seat, inbound leads with a work email, and blanks in company size, industry or job title: Clearbit, as HubSpot's enrichment. It costs no credits and needs no second contract. It will not find anyone new.
Net-new contacts with direct dials and mobiles, or intent and visitor signals, or a CRM that is Salesforce or Dynamics: ZoomInfo. The criterion is budget shape. A five-figure annual license with a 60-day notice window and a 10% renewal uplift has to fit.
A HubSpot team that also prospects: both. Native enrichment fills the inbound records, and ZoomInfo data arrives through its connector or through HubSpot's agent.
Verified emails and mobiles for named people, priced per field and without an annual license: Spona. It is the wrong pick for intent or visitor identification.

ZoomInfo vs Clearbit FAQ
Who is ZoomInfo's biggest competitor?
ZoomInfo's own annual report names LinkedIn Sales Navigator, D&B Hoovers and TechTarget as potential competitors, along with LLM and generative AI providers. Our ZoomInfo alternatives post compares the tools buyers weigh against it, and ZoomInfo vs LinkedIn Sales Navigator covers the first name on that list.
What are some alternatives to Clearbit?
Any tool that enriches records outside HubSpot, since new buyers now get Clearbit's data only inside HubSpot. The field that matters is the input: HubSpot needs a work email, while ZoomInfo and Spona can start from a name and a domain. Our Clearbit alternatives post ranks the options by the fields they fill and what they charge.
Was Clearbit acquired by HubSpot?
Yes. HubSpot completed the acquisition on December 4, 2023. New standalone subscriptions ended, and existing Clearbit accounts now add users through the linked HubSpot account. Free Clearbit accounts are no longer created.
Is ZoomInfo outdated?
Not as a product, but its records age like everyone's. ZoomInfo scores each contact on the likelihood of being reachable and still employed, and marks a company certified after confirmed activity in the last 12 months. In Spona's same-sample test, 103 of ZoomInfo's returned emails were invalid and 231 were catch-all. Spona ran that test itself, and a catch-all result is unknown, not proof of an old record.
Which is better, ZoomInfo or Clearbit?
Clearbit, as HubSpot's data enrichment, is better for a HubSpot team that needs company and job fields on inbound leads, at no credit cost. ZoomInfo is better when you need net-new contacts with phone numbers, buyer intent, or a database that works with Salesforce or Dynamics. It also needs a budget that carries an annual license. The criteria are the CRM you run, the field you lack and the contract you can sign.
