Top 12 Marketing Data Providers in 2026 (How to Use + Tools)

Bad data costs you twice. Emails bounce, ads reach the wrong accounts, and your reps burn hours chasing contacts who were never a fit in the first place.

Meanwhile, the budget goes on lists stuffed with outdated job titles, dead inboxes, duplicate records, and companies nowhere near your ICP.

Marketing data providers solve that. They help you find the right accounts, verify contact details, enrich your CRM, spot buying intent, and build campaigns around prospects worth reaching.

Below is a hands-on breakdown of 12 top providers, what each one does best, and how to actually put their data to work.

How we picked the top B2B marketing data providers on this list

Hundreds of vendors compete in this category, and every one of them claims the largest, most accurate database in the business. Those claims rarely survive contact with a real prospect list.

So we ran each tool through the checks below, weighted toward what actually determines whether the data earns its cost:

• Data accuracy → verified emails, working direct dials, current company records, and enrichment fields your team can trust without a manual spot-check. We looked hardest at bounce rates and phone connect rates, since those are where inflated database claims fall apart.
• B2B data depth → rich company and contact records with filters for seniority, department, location, industry, and technology, plus intent or trigger data where the provider offers it. Depth matters more than raw record count once your ICP gets specific.
• Workflow value → how easily you can act on what you pull. We prioritized CSV exports, native CRM sync, enrichment APIs, lead scoring, and direct connections into outreach and meeting workflows. Data that needs a manual export to become useful costs you more than the subscription does.
• Compliance and transparency → sourcing practices, GDPR and CCPA handling, DNC screening, and user permissions. This one carries extra weight for anyone selling into the EU or a regulated industry.
• Pricing structure → credit systems, seat costs, contract length, and what happens when you exceed your allowance. We favored providers with published rates and free trials, and we flagged the ones where the headline price hides platform fees, overage charges, or gated features.
• User reviews → G2 and Capterra scores alongside the recurring themes in written feedback, to confirm each platform does the specific job its homepage promises.

On top of that, we weighted the buyer use case. A tool built for ABM orchestration and a tool built for pulling emails off LinkedIn solve different problems, and ranking them on one scale tells you nothing useful. That’s why each provider below is placed according to the job it does best and the results it can realistically deliver for that job.

Best contact data providers for B2B marketing

Now, let’s compare the top contact data providers for B2B marketing based on what they do best, who they serve, and how their data flows from research to workflow execution.

1.Reply.io: best for in-depth B2B marketing data and outreach

Reply.io is an AI sales engagement platform that helps businesses find targeted leads, pick up enriched data, and launch multichannel outreach under one roof. It leads this list for one reason: it closes the gap between finding data and using it.

Data-only vendors like ZoomInfo and Cognism sell you contact and company records, then leave you to buy a sequencer, a deliverability tool, and a LinkedIn automation tool separately. Reply gives you the records along with an AI outreach engine that acts on them.

You can search 1B+ live B2B contacts and accounts across 150+ countries, filtering by industry, headcount, tech stack, department, role, and seniority. Emails are verified before export, there’s built-in enrichment to get more context about your leads, and even intent signals to prioritize leads showing potential signs of interest.

Once you have your prospect lists, you simply push them straight into tailored multichannel sequences spanning email, LinkedIn, calls, SMS, WhatsApp, and Zapier steps. Reply’s sequences follow conditional logic, meaning they adjust the channel, messaging, and timing in real time based on each lead’s engagement levels. For instance, Reply may launch a personalized cold email, schedule an automated follow-up in 3 days, and then send an automated LinkedIn connection request the same day.

Then there’s Jason AI — Reply’s very own AI sales agent that joins your team as a full-time SDR.

Jason learns your product/strategy, scores every contact against your ICP, researches each prospect and company automatically, and then writes fully tailored emails and LinkedIn messages based on all the uncovered data. You can also use its AI Web Search, where you describe your ideal buyer in plain language and Jason finds them across the web.

Finally, Jason also handles replies in your set brand voice and playbooks, answering questions, working with objections, and even booking meetings to your calendar. At $500 a month, it covers work that would otherwise take a full SDR seat, salary, tooling, and data budget combined.

Key features

• Real-time buying intent: tracks hiring activity, tech usage, funding rounds, and website visits, so you reach accounts already in the market.
• Audience suggestions: recommends accounts worth targeting before you touch a single filter.
• Contact enrichment: fills missing fields on records you already own, so AI personalization has enough context to work with.
• Multichannel outreach: coordinated sequences across email, LinkedIn, and more, while personalizing every message based on the available prospect/account context.
• Website visitor tracking: reveals which companies are browsing your site and lets you drop them into inbound sequences based on the pages they viewed.
• Deliverability kit: warms mailboxes automatically and configures SPF, DKIM, and DMARC in minutes, with Google Postmaster monitoring on top.

Pros

• 1B+ contact database with live search rather than static exports
• Data and outreach in a single platform
• Built-in email verification before export
• AI SDR that handles prospecting, personalization, replies, and booking
• True multichannel sequences with conditional logic
• Full deliverability and inbox placement toolkit

Pricing

Plans start at $49 per user per month for email-focused outreach and $89 per user per month for multichannel, both billed annually with unlimited mailboxes. Jason AI is priced separately from $500 per month, and there’s a 14-day free trial on the core platform.

2. ZoomInfo: best for enterprise GTM intelligence

ZoomInfo runs one of the largest B2B databases in the category. The company reports 321M+ professional profiles across 104M+ companies, layered with org charts, technographics, and buying intent inside a single GTM platform.

Its Copilot layer sits on top of that data, recommending which accounts to prioritize and when to reach out based on recent buying activity.

The depth suits enterprise revenue operations. You get Salesforce and HubSpot integrations, automated CRM refresh, and admin tooling built for large sales orgs with dedicated data ops staff behind it.

The trade-off is cost and commitment. ZoomInfo is the most expensive option on this list, requires annual contracts with a three-seat minimum, and prices intent data as a separate add-on rather than bundling it into the base plan.

Key features

• Copilot AI: recommends accounts and next moves based on buying activity.
• WebSights: identifies companies visiting your website.
• Org charts: maps decision-makers and reporting lines inside target accounts.
• Intent data: tracks accounts researching topics linked to your product.
• Enrichment workflows: refreshes CRM records automatically as data changes.

Pros

• Largest B2B contact database in the category
• Deep enterprise integrations
• AI-assisted account prioritization

Cons

• No monthly billing option
• Three-seat minimum purchase
• Intent data priced as an add-on
• Strict 60–90 day cancellation window

Pricing

ZoomInfo doesn’t publish pricing. Third-party contract data puts the Professional plan around $14,995 per year for three seats and 5,000 annual credits, with Advanced near $24,995 and Elite near $39,995. Final quotes vary by seats, credits, and add-ons.

3. Cognism: best for compliant B2B data in Europe

Cognism built its name on compliant European data. Its Diamond Data set contains phone-verified mobile numbers, which the company puts at 98% accuracy, and contacts are screened against do-not-call lists across multiple European markets.

Few providers match that level of rigor in the GDPR space, which is why Cognism tends to win on cold-calling programs that live or die on mobile connect rates.

A London SaaS vendor, for instance, can find finance directors in Germany, verify their mobile numbers, screen them against DNC registries, then push clean records into the CRM.

Cognism is a data provider rather than an outreach platform, so you’ll pair it with a sequencing tool like Reply.io to actually work the lists it produces.

Key features

• Bombora intent data: ranks accounts by research activity on topics you choose.
• Chrome extension: pulls contact details from LinkedIn profiles and company websites.
• CRM enrichment: refreshes stale Salesforce and HubSpot records on a schedule.
• Technographics: filters prospects by the software their company runs.
• Unrestricted viewing: lets users browse records under a fair-use policy, without per-view credits.

Pros

• ISO 27001 and SOC 2 certified
• 24/7 live chat support
• Integrations included at no extra cost

Cons

• Quote-only pricing
• No monthly billing
• Intent data limited to the higher tier

Pricing

Cognism doesn’t list pricing publicly. Third-party contract data points to a platform fee around $15,000 per year on the entry tier, plus roughly $1,500 per user annually on top. Final cost varies by seat type, region, data package, and renewal term.

4. Breeze Intelligence by HubSpot: best for enriching inbound leads

Breeze Intelligence is HubSpot’s native enrichment layer, built on the Clearbit dataset HubSpot acquired and rebranded. It fills CRM records with firmographic and technographic detail from 200M+ company and buyer profiles, so inbound leads arrive scored and routed rather than raw.

If a prospect submits a form with nothing but a name and an email, Breeze appends company size, industry, and tech stack before the lead reaches your sales queue. Your reps qualify in seconds instead of opening five tabs.

The catch is the ecosystem. Breeze only works inside HubSpot, which is a meaningful constraint next to providers that connect to any CRM from, Salesforce to Pipedrive.

Key features

• Visitor identification: reveals the companies behind anonymous website traffic.
• Buyer intent: spots accounts researching solutions in your category.
• Smart properties: generates custom AI-populated fields on any record.
• Workflow triggers: starts HubSpot automations the moment new data lands.
• Continuous updates: re-enriches records automatically when company details change.

Pros

• No separate vendor contract
• Bundled credits on paid plans
• Familiar HubSpot interface

Cons

• Credits expire monthly
• No phone number data
• HubSpot subscription required

Pricing

Breeze Intelligence starts at $45 per month for 100 credits, on top of a paid HubSpot subscription. Standard enrichment is now included with HubSpot Core Seats, so the paid credits mainly cover AI-generated Smart Properties.

5. Kaspr: best for LinkedIn-first contact capture

Kaspr earns its place by making LinkedIn prospecting almost frictionless for reps, recruiters, founders, and small sales teams.

Install the Chrome extension, open a profile, click once, and it surfaces verified phone numbers and email addresses on the spot. Kaspr checks its 500M+ contact records against 150+ sources in real time before returning a result.

From there you can save leads, build lists, leave notes, export records, enrich CSV files, and sync everything to HubSpot, Salesforce, or Pipedrive.

Kaspr is also part of the Cognism group, which lends real weight to its data sourcing and compliance claims. Its focus is contact capture during LinkedIn research rather than the full path from data to booked meeting.

Key features

• Bulk extraction: pulls up to 2,500 profiles from Sales Navigator lists.
• LinkedIn cadences: automates connection requests and follow-up messages.
• CRM sync: sends leads to Salesforce, HubSpot, and Pipedrive.
• Enrichment workflows: completes missing details on saved lead lists.
• In-app dialer: lets reps call prospects straight from the Kaspr dashboard.

Pros

• Generous free plan
• Fast, low-friction LinkedIn prospecting
• Quick CRM export

Cons

• Limited phone credits on lower tiers
• Three separate credit pools to track

Pricing

Kaspr starts at $49 per user per month for Starter on annual billing, with Business at $79 per user per month. Monthly billing runs roughly 25% higher, and the Organization tier is custom-quoted.

6. Lead411: best for trigger-based outbound data

Lead411’s strength is timing. The platform tracks growth events like funding rounds, hiring surges, and new tech adoption, then alerts you the moment a target account shows one, so you reach out while budget is still fresh.

Behind that sits a 450M+ contact database with verified emails and direct dials. Lead411 puts its email accuracy at 96% through a mix of human and AI verification.

It’s a strong fit for SMB and mid-market outbound teams that want prospect lists built around timing rather than static filters. A payroll software vendor can search for companies hiring HR leaders, filter by size, pull verified contacts, and start outreach before competitors notice the same signal.

Two things to plan for: Bombora intent sits on the higher Ignite tier and requires an annual commitment, and every plan caps monthly exports.

Key features

• Bombora intent: shows which accounts are researching your product category right now.
• Reach automation: sends email and SMS cadences from inside Lead411.
• AI search assistant: builds prospect lists from plain-language prompts.
• Chrome extension: grabs contact details while you browse LinkedIn.
• CRM integrations: syncs with 25+ tools, including Salesforce and Outreach.

Pros

• Affordable entry pricing
• Strong SMB package
• API access available

Cons

• Intent data requires an annual plan and a tier upgrade
• Monthly export caps on every plan
• Less depth outside North America

Pricing

Lead411’s entry Spark plan runs around $75 per user per month on annual billing, or $99 month-to-month. Intent data starts at the Ignite tier, reported between $1,500 and $3,000 per year depending on export volume and data package.

7. Hunter.io: best for email finding and verification

Hunter.io does one job and does it cleanly: finding and verifying business email addresses.

Enter a company domain and Domain Search returns every address Hunter has indexed, each with a confidence score. Enter a name and a domain instead, and Email Finder returns the address. Every result can be run through the Email Verifier before it hits a sequence.

That makes Hunter a natural fit for content marketers, link builders, agencies, recruiters, and lean outbound teams who already know exactly which company or person they want to reach.

Hunter’s scope is deliberately narrow. There’s no prospecting database, no intent layer, and no multichannel outreach, so most teams pair it with a platform that handles the sending side.

Key features

• Campaigns: sends cold email sequences from a connected Gmail or Outlook account.
• Bulk tasks: processes entire CSV lists of names or domains at once.
• Chrome extension: reveals emails while you browse company websites.
• Google Sheets add-on: manages contact data inside your spreadsheets.
• API access: feeds email lookups into your own tools and workflows.

Pros

• Genuinely useful free plan
• Transparent, published pricing
• API and Google Sheets access

Cons

• Email-only data scope
• No phone numbers or intent signals
• Credits consumed per lookup attempt

Pricing

Hunter starts at $49 per month for Starter with 2,000 credits. Annual billing drops Starter to $34 per month, Growth to $104, and Scale to $209. All plans include unlimited team seats.

8. Clay: best for multi-source enrichment workflows

Clay takes a different approach to the rest of this list. Rather than selling you one database, it lets GTM operators build custom enrichment tables that pull from many sources at once.

You can run waterfall lookups across 200+ providers, ask Claygent to research an account in plain language, layer in signals, and push the finished records into your CRM or sequencer.

That flexibility pays off most when your lists are messy or your ICP rules are unusually specific. A RevOps builder can upload target accounts, find the right personas, enrich emails, append tech stack, check hiring pages, score the accounts, and route only the best records forward.

Clay handles the enrichment logic. You’ll still want an execution layer on top for sequencing, deliverability, and reply handling, whether that’s Reply.io or something similar.

Key features

• Waterfall enrichment: checks providers in sequence until it finds a match.
• Claygent AI: researches companies and contacts from plain-language prompts.
• Signals: tracks job changes, promotions, and web activity.
• Data marketplace: connects 200+ data and AI vendors.
• CRM enrichment: pushes enriched fields to Salesforce or HubSpot.

Pros

• Best-in-class enrichment logic
• Access to many vendors through one contract
• Powerful research agents

Cons

• Credits burn fast on heavy workflows
• Steep setup curve, often needs a dedicated operator

Pricing

Clay restructured its plans in March 2026. Launch starts at $185 per month ($167 billed annually) and Growth at $495 per month ($446 annually), with custom Enterprise pricing above that. All plans include unlimited seats.

9. Ocean.io: best for lookalike account discovery

Ocean.io approaches list building from the other direction. Instead of filtering a database, you feed it your best customers and its AI finds companies that resemble them across 67M company profiles, 100+ data points, and 250M+ employee records.

That makes it genuinely useful when you’re entering a new market or tightening a fuzzy ICP. A cybersecurity vendor can upload five happy customers, surface similar mid-market firms, filter by region and headcount, then export straight to the CRM.

Like most data-only tools here, Ocean.io stops at the list. Pair it with an outreach platform to turn those accounts into conversations.

Key features

• Lookalike search: finds companies that resemble your existing customers.
• Company search: filters accounts by size, location, industry, and growth data.
• Employee profiles: adds contacts from its 250M+ profile database.
• API access: sends company search and enrichment data into your stack.
• Intent data: surfaces accounts researching topics related to your product.

Pros

• Excellent for ICP discovery and market expansion
• Large company database with deep firmographics
• API access on paid plans

Cons

• No outreach functionality
• Contact coverage thinner outside Western Europe
• Tiered credit costs add up on phone lookups

Pricing

Ocean.io’s Starter plan runs $79 per month billed annually with 500 credits each for companies, contacts, and verification. Professional sits around $299 per month with 2,000 credits and CRM integrations, and there’s a 14-day free trial.

10. Demandbase: best for ABM account intelligence

Demandbase blends firmographics, technographics, Bombora intent, and web activity into a single account score that predicts purchase likelihood.

Its standout piece is the native B2B ad engine. When a target account’s score climbs, ad intensity rises with it automatically. When that account books a meeting, the ads cool off. An enterprise security vendor can run that loop across a 500-account list so every buying group sees relevant creative at whatever stage they’re actually in.

The budget required puts Demandbase firmly in enterprise territory. Contracts are quote-only, seats are billed on top of the platform fee, and onboarding is a separate line item. Most of the providers on this list let you test the data long before you reach five figures.

Key features

• Agentbase AI: runs agents that optimize campaigns, accounts, and pipeline.
• Buying group maps: identifies every stakeholder inside a target account.
• Website personalization: adjusts site content by visiting account and buying stage.
• Sales intelligence: adds contact data and org charts from InsideView.
• Connected TV ads: reaches target accounts beyond display and LinkedIn.

Pros

• AI agents included for platform customers
• 30+ native integrations
• Deep enterprise reporting

Cons

• No free trial
• Minimum ad spend commitments
• Separate onboarding and per-seat fees

Pricing

Demandbase pricing is quote-only. Vendor contract data puts the median around $65,000 per year, with entry deployments reported near $24,000 and full enterprise builds passing $100,000. Onboarding is billed separately and commonly reported around $29,000.

11. 6sense: best for predictive intent data

6sense answers a question most data providers can’t: when will this account actually buy?

Its predictive models sort target accounts into buying stages, from Awareness through Purchase, so your team engages on the account’s timeline rather than yours. The platform also illuminates the dark funnel, showing the anonymous research prospects do long before they fill in a form.

If you sell data warehouses on a nine-month cycle, 6sense can show which accounts crossed into the decision stage this week, letting reps call while the evaluation is still live.

It does ask for patience and budget. Implementation typically runs two to three months, contracts usually span two years, and G2 reviewers report a median time to ROI around 11 months.

Key features

• Sales Copilot: recommends next actions and drafts outreach for reps.
• Web visitor ID: reveals anonymous companies browsing your site.
• Audience segments: builds target lists from firmographic and behavioral filters.
• ABM advertising: serves display ads to in-market accounts.
• Conversational email: sends automated replies that qualify engaged prospects.

Pros

• Free tier available for testing
• Psychographic and technographic filters
• Deep CRM integrations

Cons

• Steep learning curve
• Credits expire monthly
• Multi-year contracts standard

Pricing

6sense doesn’t publish paid pricing. Third-party reports put deployments between roughly $35,000 and $300,000 per year depending on credits, package, and company size. A free Revenue AI for Sales plan with 50 monthly credits is available for testing.

12. Bombora: best for third-party topic intent

Bombora’s Data Co-op aggregates activity from 5,000+ B2B publishers, brand sites, and data partners, then scores companies showing unusual research activity around the topics you select.

That makes it a strong fit for demand gen and ABM teams who already have ads, CRM, and sales engagement in place and simply need a better signal feeding them. A cloud security vendor can monitor accounts surging on “zero trust,” route those accounts to sales, and push matched audiences into ad platforms the same day.

Bombora reports at the account level only. You’ll know a company is in-market without knowing who to email, so it works best alongside a contact database and an outreach engine like Reply.io that can turn the signal into a conversation.

Key features

• Company Surge: scores accounts with rising topic research.
• Data Co-op: draws on publisher and brand site activity.
• Topic clusters: tracks research themes tied to your category.
• 100+ integrations: sends intent data into CRM, ad, and martech tools.
• Audience activation: builds campaign and sales alert segments.

Pros

• Deep, well-established intent dataset
• Broad integration network
• Highly rated as an ABM data source

Cons

• Quote-only pricing
• Account-level signals only
• No native outreach

Pricing

Bombora pricing is quote-only. Third-party reports place entry Company Surge packages between $25,000 and $30,000 per year, with larger topic packages reaching $100,000+. Additional intent topics beyond the included set typically run $200 to $400 each annually.

Wrapping up

The right provider comes down to the job in front of you. Compliance-heavy markets, messy lists, buying signals, and net-new territory all pull toward different tools, so start from the gap you actually have rather than the biggest database on the list.

And if the goal is data that turns into booked meetings rather than another list to clean up, Reply.io covers both ends: 1B+ verified contacts, multichannel sequences, and Jason AI autonomously finding and researching leads, running the outreach, and booking meetings on your calendar.

Start your free 14-day Reply.io trial and put your marketing data to work.
