10 Best B2B Contact Databases 2026 for B2B Teams

Which B2B contact database is best?

The best B2B contact database depends on your budget, company size and target region: ZoomInfo leads for enterprise scale, Apollo.io for SMB value, Cognism for EMEA compliance and mobile data, and FullEnrich is best overall for email and mobile accuracy across regions, with a waterfall across 20+ providers, every result verified and billed only when found.

Disclosure: we make FullEnrich, so it's listed first, with its cons.

What makes a B2B contact database good?

A good B2B contact database finds the people in your segment, keeps their details current, and bills you in a way you can forecast. Five things decide it:

• Filters that fit your company size: title, seniority, headcount, industry and location should describe your buyer without a list import. Coverage thins on smaller companies; ColdIQ, an outbound agency, notes in its guide to B2B data layers that "Mainstream databases go thin below mid-market."
• How records stay current: a published refresh cycle, verification at export, or a live check at request time. ZeroBounce, which sells email verification, reports from more than 11 billion addresses that "at least 23% of an email list decays within just one year."
• What triggers billing: viewing, revealing, exporting, or only a verified result. Apollo.io, for example, charges 1 credit per verified email and 8 per phone number.
• Mobiles in the countries you call: Cognism's phone-verified data covers 10m+ contacts, and every vendor's coverage shifts by country, so test the countries on your dial list.
• Contract terms: ZoomInfo's paid plans are annual and mostly billed upfront, while several tools here run month to month. Check how much notice a renewal needs.

All 10 tools return emails or phones for people you don't have yet. LinkedIn Sales Navigator hands you neither, and Clay is a workflow builder that orchestrates other tools, so it sits with data enrichment tools. The wider vendor field is in our guide to B2B data providers.

Why trust us?

A contact is only worth something if the number rings and the email lands. I co-founded FullEnrich and run its product, and that idea shapes how I read every tool on this list.

FullEnrich doesn't own a database. For every contact, it asks 20+ providers in turn and keeps only what passes verification. That puts us in an unusual seat: we see which providers come back empty or fail verification on each contact. Of the data we buy from providers, 31.53% fails our checks. We don't deliver it and we don't bill it.

Many teams we talk to don't replace ZoomInfo, Apollo or Cognism. They run FullEnrich next to it, and they tell us where their database breaks: a head-office line labeled as a mobile, a renewal notice nobody read. One customer compared 500 contacts in FullEnrich and ZoomInfo. Both found a mobile for 255 people, and the numbers matched 45% of the time.

So I read each tool below for two things: how much of your list it can reach, and what you pay per contact.

The 10 best B2B contact databases at a glance

Prices from vendor pricing pages, ratings from G2, October 2026.

1. FullEnrich

FullEnrich G2 rating: 4.8/5 (246 reviews)

FullEnrich Search counts the people who match your filters before you spend a credit.

FullEnrich is a waterfall enrichment platform: sales teams, recruiters and AI agents use it to get work emails, personal emails and mobile numbers, each checked before delivery. It's best overall for email and mobile accuracy across regions: a waterfall across 20+ providers, every result verified, billed only when found.

FullEnrich charges for what it finds. You build a list in FullEnrich Search, free to browse, and each person runs through the providers in turn until a result passes verification. A work email costs 1 credit and a mobile 10; a miss or a landline costs nothing. Your spend follows the contacts you can reach, and a thin segment simply costs less.

A US search for software sales leaders at 11-200-person companies founded since 2018 returns 2,193 people, browsed free before any credit is spent.

Free misses make FullEnrich a natural second pass. A setup we see often: ZoomInfo or Apollo runs first, only the contacts it missed come to us, and the team pays only for the gaps we fill.

Best for: B2B sales teams, agencies and recruiting firms prospecting in more than one country.

Key features

• Waterfall enrichment: 20+ providers queried one after another until an email or mobile passes verification. Mobiles are checked for line type and active status, so reps don't dial dead lines.
• People search: filter by title, seniority, industry, headcount, location and job changes, then enrich the list in the same place.
• Reverse email lookup: turn a Gmail or Outlook sign-up into a name, company and LinkedIn profile for 1 credit.
• MCP server: ask Claude, Cursor or another MCP-compatible agent for a type of prospect and get verified contacts back in the chat.

Pros

• Your budget goes on results: misses and landlines are free
• Room for the whole team: unlimited users on every plan, including the trial
• Leftover credits carry over: 3 months on a monthly plan, a full year on a yearly one
• Ready for a security review: SOC 2 Type II and GDPR compliant

Cons

• Account research needs a second tool: no intent data or in-house research team
• Catch-all emails cost a credit when found

What users say: Maja Voje (GTM Strategist) had a coverage test run on her niche and reported that "the best coverage actually came from FullEnrich in our case".

Pricing: 50 free credits, no card. Pro starts at $29/month for 500 credits ($26 billed yearly); 1,000 credits a month cost $55, so about $0.055 per email and $0.55 per mobile.

FullEnrich Pro at 1,000 credits a month: $55, or $0.055 a credit.

Try FullEnrich with 50 free credits, no card required.

Skip it if you want intent data and org charts from the same vendor as your contacts; ZoomInfo bundles them.

2. ZoomInfo

ZoomInfo G2 rating: 4.5/5 (9,198 reviews)

ZoomInfo now sells itself as an AI platform for go-to-market teams, with the B2B database underneath.

ZoomInfo is a B2B go-to-market intelligence platform: contact data, intent, technographics and org charts on 500M+ contacts and 100M+ companies, by its own count. It's the enterprise standard for large sales teams selling into US accounts, with the contacts and the account research around them under one contract.

ZoomInfo sells a year at a time. Paid plans are quoted, annual and mostly billed upfront, and auto-renewal with 30 to 90 days' notice is common. Put the opt-out date in your calendar on day one.

All of it comes as one bundle, used or not. Buyers we talk to describe reps who search in Sales Navigator and open ZoomInfo's extension only for the mobile; at one company, that seat-usage data ended the renewal.

Best for: Mid-market and enterprise sales teams selling into US accounts.

Key features

• Contact and company search: filter 500M+ contacts by role, seniority, technographics and company attributes to build a territory from one source.
• Intent data: surfaces accounts researching topics you sell into, so reps start with accounts already looking.
• CRM enrichment: fills Salesforce and HubSpot account and contact fields from ZoomInfo's data.
• GTM Studio: queries ZoomInfo and third-party vendors together, so a ZoomInfo miss can still come back filled.

Pros

• One signature buys the whole account view: contacts, intent, technographics and org charts in one contract
• Strong US coverage, with a confidence score that tells reps which records to trust
• Quotes have room to move: buyers cut them 22% on average on Vendr's data

Cons

• Reps can dial dead lines: head-office numbers sit beside mobiles
• A missed renewal window gets expensive: auto-renewals often carry 5-10% yearly increases on Vendr's data

What users say: Jonathan Pierce found his contract renewed anyway. He told ZoomInfo he wouldn't renew, then wrote on LinkedIn that "on the day it autorenewed they sent me a quote for $40,000, mind you when I was previously on $8k/yr." Cotera paid $42,000 a year for contact information before it moved its four-person outbound team off ZoomInfo.

Pricing: ZoomInfo Lite is free with 10 credits a month. Paid plans are quote-only; the median buyer pays $33,500 a year, with 30 to 90 days' renewal notice, on Vendr's procurement data. Our ZoomInfo pricing breakdown covers the plans and contract terms.

ZoomInfo pricing: each plan leads to a quote form.

Skip it if you sell mostly outside the US or prospect alone: a contract built for large US teams is hard to justify for one seat. Our list of ZoomInfo competitors has lighter options.

3. Apollo.io

Apollo.io G2 rating: 4.7/5 (9,848 reviews)

Apollo's free plan starts without a credit card.

Apollo.io is an all-in-one sales platform: 240M+ contacts and 30M+ companies, with sequences, a dialer and a Chrome extension behind one login. It's the best value for small teams running their first outbound, because one subscription covers both finding people and reaching them.

Apollo's pricing rewards email and punishes phones. A verified email costs 1 credit, a phone number costs 8, and unused credits expire at the end of each billing cycle, purchased add-ons included. So a team that writes emails stretches a plan a long way, a team that calls burns through it, and whatever is left when the billing cycle ends is gone.

On our calls, Apollo users keep it for sequencing and the dialer and buy their mobiles somewhere else: a number costs 8 credits, and too many come back as head-office lines.

Best for: Early-stage B2B startups and SMB sales teams running their first outbound.

Key features

• Sequences and dialer: email steps and calls run from the same contacts you searched, so nothing is exported between tools.
• Chrome extension: reveal a contact while you're on their LinkedIn profile or company site.
• Intent data: Bombora-powered topics show which accounts are researching what you sell.
• Waterfall enrichment: extra email and phone verification from third-party providers, on top of Apollo's own data.

Pros

• Strong value for email-led outbound: search, sequences and a dialer for one seat price
• A free plan you can actually prospect with: 900 credits per seat a year, enough to test a segment before you pay
• Only verified emails cost a credit, so a segment full of bad addresses doesn't drain the plan

Cons

• Phone-heavy teams pay 8 times the email price: 8 credits a number, on credits that expire each cycle
• Growing teams hit a seat floor: the Organization plan needs 3 seats

What users say: One user had Apollo's AI agent build a US-only list, and the agent counted blank location fields as a match. In an r/UseApolloIo post about the credits it spent, they wrote: "The AI just burned through 10,392 of my paid credits on people that violated the exact prompt I gave it."

Pricing: Free plan available. Basic costs $49, Professional $79 and Organization $119 per seat a month, billed yearly. Our Apollo pricing guide works out what each plan costs per email and per phone.

Apollo prices each paid plan per seat and shows yearly billing first.

Skip it if your reps spend their day on the phone. At 8 credits a number, phone-first prospecting is where Apollo gets expensive; our Apollo alternatives cover tools built for calling.

4. Cognism

Cognism G2 rating: 4.5/5 (1,376 reviews)

Cognism's homepage puts its European data first.

Cognism is a sales intelligence vendor built around Europe. It's the pick for EMEA compliance and mobile data: 10m+ contacts whose mobile number was confirmed by a call that checked the right person answers.

That call is what you're paying for. A mobile pulled from a database can be stale or belong to someone else; a number Cognism has rung and matched is one an SDR can dial with confidence. On the Pro package, a "Verified mobile numbers only" filter shows how many of those numbers exist in your segment before you spend a credit, so you know before you buy how much of your list Cognism has phone-verified.

The trade-off is the contract. Both packages start at 5 seats with no public price, and the verified-mobile filter sits on Pro. On our calls, Cognism is the EMEA contract and a separate vendor covers the US, because teams buy it for UK and European coverage.

Best for: Mid-market B2B companies cold-calling the UK and Europe.

Key features

• Phone-verified mobiles: numbers confirmed by a call to the right person, marked with a diamond icon.
• Enrich add-on: keeps a contact current and charges again only when key details change, like a job move.
• Do-not-call checks: numbers are cross-checked against national DNC lists before your reps dial.

Pros

• Phone-verified mobiles for Europe, each confirmed by a call to the right person on Cognism's own method
• Re-viewing a contact is free, so a rep can come back to a lead without paying twice
• Director-level contacts refreshed every 30 days, 95% of them on Cognism's own figures

Cons

• Sold to teams: both packages start at 5 seats, with no public price
• Built for Europe first, so a US-heavy pipeline needs a second vendor

What users say: A G2 reviewer invited by Cognism found gaps in both the data and the search, writing in a review of Cognism's contact data: "Sometimes the contact information is incomplete or outdated, and the search and filtering options could be more intuitive and precise."

Pricing: Price on request. Standard and Pro each include 5 seats with credits per seat, at 1 credit per revealed contact, and extra credits can be bought anytime. Our Cognism pricing breakdown goes through both packages in detail.

Neither Cognism package shows a price, and both start at 5 seats.

Skip it if one rep needs LinkedIn lookups rather than a team calling Europe. Kaspr, which Cognism owns, is the lighter option (Kaspr pricing); our Cognism alternatives cover US-leaning tools.

5. Lusha

Lusha G2 rating: 4.3/5 (1,670 reviews)

Lusha sizes its data at 515M+ contacts and now promotes a connection to Claude.

Lusha sells emails and phone numbers one contact at a time to SDRs and AEs, through a browser extension or its own search, from an index of 515M+ contacts. It suits quick lookups on LinkedIn: the extension puts a number on the profile a rep is already reading.

You see what a contact holds before you pay for it. Every search shows which fields exist, and only then does an email cost 1 credit or a phone 5. Coverage on your own list is free to gauge.

Lusha's self-serve plans stop at 5 users, and every login is a paid seat. Teams we talk to with more reps than licences end up swapping seats all year, and one login locks out the other.

Best for: SDRs and AEs at small and mid-size companies looking up contacts one at a time from LinkedIn.

Key features

• Browser extension: reveal contacts on LinkedIn and company websites without switching tabs.
• Field preview: see whether an email or phone exists before you pay for it.
• Waterfall option: 2 credits per confirmed email, 8 per confirmed phone, nothing when no result comes back.
• Web search: build whole lists in Lusha's own search as well as from the extension.

Pros

• Cheap to start: a permanent free plan, and Starter at $37.45 a month billed yearly
• Fewer stale reveals to pay for: data refreshed on every search, by Lusha's account
• Monthly plans forgive a slow month: unused credits roll over, up to twice the plan's limit

Cons

• Phone-heavy reps burn credits fast: 5 per phone, with no refund if it comes back incomplete
• Yearly plans lose leftovers: annual credits reset at year end

What users say: One G2 reviewer found emails held up better than phones outside North America. In a G2 review of Lusha, they wrote: "While business emails tend to be reliable, phone number accuracy drops noticeably outside North America or for mid-level employees."

Pricing: Free with 40 credits a month. Starter costs $37.45, Pro $52.45 (2 seats) and Premium $299.95 a month, billed yearly. Our Lusha pricing guide works out the credit math on each plan.

Lusha's yearly plans, with the slider set to Premium's 40,800 credits.

Skip it if your team is larger than 5 users and wants self-serve billing, since past that size buying goes through sales. Our Lusha alternatives page has other options.

6. Seamless.AI

Seamless.AI G2 rating: 4.4/5 (5,417 reviews)

Seamless.AI's homepage leads with AI-assisted prospecting and a dashboard of calls and emails.

Seamless.AI is an AI prospecting platform that builds contact lists through real-time search, across more than a billion contacts. It suits US outbound teams prospecting at volume, because the AI builds large lists from your filters.

Seamless.AI sells volume on a yearly commitment. Basic carries 250 credits a month and Pro 10,000, and every subscription is annual. Whatever you sign holds for a year, and the real deadline to leave falls 60 days before the renewal.

With no public prices, the order form sets your terms. One buyer told us the agreement they received matched nothing they had discussed with sales for months, so read it line by line.

Best for: US SMB and mid-market outbound teams prospecting at volume.

Key features

• AI-assisted list building: large lists built from your filters with AI help.
• Universal credits: one credit type for every reveal, with no separate email and phone budgets.
• Credit-back on invalid emails: an invalid email returns its credit automatically.

Pros

• Built for volume: Pro carries 10,000 credits a month
• You can test the search first: a free license comes with 50 credits that don't replenish
• Profiles you can segment on: 100+ data points each, updated continuously as Seamless describes them

Cons

• Wrong phone numbers still cost a credit: credit-back covers invalid emails only
• Hard to budget before a demo: no public prices

What users say: One buyer expected a trial, found an annual contract, and posted billing's reply in an r/SaaS thread on Seamless.AI's annual contract: "We're sorry all contracts with seamless are annual and it will cancel when my year is up."

Pricing: No public prices; the pricing page asks how many contacts you need and leads to a demo, and each reveal costs 1 credit. Every subscription is annual under Seamless's terms. Our Seamless.AI pricing guide gathers what's known, so you walk into the demo with a benchmark.

Seamless.AI asks for your monthly contact volume instead of showing a price.

Skip it if you want to prove a list works before committing a year, because a failed test on an annual plan still runs twelve months. FullEnrich's plans run month to month.

7. UpLead

UpLead G2 rating: 4.7/5 (832 reviews)

UpLead's contact search, where one credit buys a contact's email and mobile.

UpLead is a contact data provider for small teams running email-first outbound, with 200M+ leads. Its name rests on verified emails and clean lists.

Every export gets checked on the way out. One credit gets you a contact, with email and mobile direct dial, and each email is verified as it leaves for a download or your CRM. Lists leave freshly checked, and one credit covers both channels when both exist.

UpLead measures its 95% guarantee at download, with no zero-bounce promise once you send, and accept-all addresses need suppressing. Before a large send, run your own bounce check on anything that has waited a while.

Best for: Small US B2B companies sending email-first outbound.

Key features

• Freshness ranking: leads are ranked by freshness, so recent records come up first.
• Email and mobile per credit: one credit buys both, so cost per contact is easy to forecast.
• CRM export: send paid contacts straight to your CRM.

Pros

• Lists start freshly checked: a 95% accuracy guarantee on UpLead's own terms, applied at download
• Easy to start and stop: monthly plans carry no contract, and only Professional is annual
• A 7-day trial with 5 credits, enough to spot-check contacts you already know

Cons

• No zero-bounce promise once you send: the 95% guarantee is measured at download
• Accept-all emails shrink a usable list: they need suppressing or separate handling

Pricing: Essentials costs $99 a month for 170 credits (about $0.58 per contact), or $74 a month billed yearly; Plus is $199, or $149 yearly, and Professional is custom. Our UpLead pricing breakdown covers each plan.

UpLead's monthly prices; only Professional requires annual billing.

Skip it if you need accuracy promised at the moment you send, since UpLead measures it at download. Our UpLead alternatives compare other email-first tools.

8. RocketReach

RocketReach G2 rating: 4.4/5 (1,385 reviews)

RocketReach search with role and industry filters, built for finding a specific person.

RocketReach is a contact lookup tool that searches 700 million professionals for emails and phone numbers. Recruiters and sellers who start from a name and company use it to find one known person, and a lookup returns personal emails alongside work ones when RocketReach has them.

RocketReach charges only for a good result: an A or A- grade email or a valid phone. Searching, misses and re-lookups on an active plan are free. A hard-to-find candidate costs nothing until they turn up.

Phones are where its idea of success gets generous: a lookup counts when 1 of the 5 numbers returned is active for the right person. Outside the US the results thin out too: one recruiting team we spoke with, running EMEA projects, told us that stacking RocketReach with other US-strong tools returned nothing most of the time.

Best for: Recruiting firms and agency recruiters contacting specific candidates.

Key features

• Graded emails: each email carries a deliverability grade, so you know which ones to send.
• Personal and professional emails: useful when a candidate's work inbox is the wrong channel.
• 700M professionals: search across 60 million companies by name or role.
• 50+ search filters: narrow by role, company and industry when you don't have a name yet.

Pros

• Spend per person is predictable: one profile never costs more than one credit, and misses are free
• Credits you don't use stay yours: monthly website plans roll them over
• Easy to try: 5 free lookups with no card

Cons

• Reps may dial several numbers to reach one: success means 1 of 5 works
• Volume teams hit a ceiling: "unlimited" plans cap exports, from 1,200 a year on Essentials, which is email only

What users say: One commenter found only one channel working at a time. In an r/sales thread on mismatched emails and phones, they wrote: "Either the email bounces but the phone number works, or the phone number bounces but the email works." An exec-search agency in an r/SaaS thread on RocketReach mobiles found German, Dutch and UK numbers old or wrong.

Pricing: Essentials costs $33 a month ($399 a year), Pro $75 ($899) and Ultimate $142 ($1,699), billed annually. Our guide to what RocketReach is explains how its lookups and grades work.

Each RocketReach plan lists its yearly export cap under the price.

Skip it if your calling list is mostly European mobiles, where the agency above found numbers old or wrong.

9. Lead411

Lead411 G2 rating: 4.5/5 (482 reviews)

Lead411 pitches unlimited data on its homepage, from $49 a month.

Lead411 is a budget B2B contact database for small US teams watching every dollar: US emails on every plan and direct dials from the Ignite plan up. It's a low-cost route to US exports: Spark works out to about $0.05 a contact on monthly billing and $0.04 on yearly, and annual plans add buyer intent.

Exports are the unit, and unused ones carry over. Spark includes 1,000 a month for $49, and whatever you don't use rolls into the next cycle, so a quiet month wastes nothing you paid for.

The catch with Lead411's price is freshness: emails are re-verified every 3 to 6 months, the slowest stated cycle on this list. Any list that has sat for a quarter deserves a re-check before it goes into a sequence.

Best for: US small businesses selling to other SMBs on a tight budget.

Key features

• Buyer intent: on annual plans, ranks accounts already researching a purchase, so reps call the warm ones first.
• Rollover exports: unused exports carry into the next billing cycle.
• Email verification: SMTP checks, human verification and open validation, with catch-alls verified mainly through BounceBan.

Pros

• Cheap enough to test outbound: $49 a month on Spark
• A trial that answers the coverage question: 7 days and 50 exports, enough to look up your current customers
• No lock-in: monthly plans cancel any time

Cons

• Spark buyers hit a limit the homepage doesn't mention: it says "without export caps", but Spark caps exports at 1,000 a month
• Callers need a bigger plan: direct dials start on Ignite, from $150 a month

What users say: One buyer looked up companies they already did business with and found about 1 in 10 of them, as they reported in an r/advancedentrepreneur thread on Lead411.

Pricing: Spark costs $49 a month for 1,000 exports (about $0.05 per contact) or $490 a year. Ignite starts at $150 a month ($1,500 billed yearly), with Blaze priced on request. Our Lead411 pricing guide covers what each plan includes.

Direct phone numbers are struck through on Lead411's Spark plan.

Skip it if your buyers sit outside the US or in a niche the trial can't find, since Lead411 is built around US data. Our Lead411 alternatives list other options.

10. SalesIntel

SalesIntel G2 rating: 4.3/5 (540 reviews)

SalesIntel's homepage funnel runs from total addressable market down to in-market signals.

SalesIntel is a data provider with 200M+ contacts and 54M+ mobile numbers, sold to US teams with no seat limits. That makes it the choice for human-verified US data with unlimited users: researchers check records, and everyone on the account can export.

The bill follows the account, so every user on it can export. Exports and enrichment are unlimited per user, and Research on Demand, where researchers find a contact for you, is capped at 10 credits per user a month. Hiring another rep doesn't add a seat to pay for.

Only part of the database gets the human check, and the 90-day refresh applies to those records alone. So coverage has gaps too: one small team we work with, on a multi-year SalesIntel contract, filled its missing mobiles by running Claude across Sales Navigator and SalesIntel.

Best for: US mid-market B2B companies in niche verticals.

Key features

• Human-verified records: researchers re-check contacts on a 90-day cycle.
• Research on Demand: researchers find a missing contact for you, up to 10 per user a month.
• Intent and technographics: 60,000+ intent topics and 42,000+ technologies tracked, next to contact search.
• Verified mobiles: 54M+ verified mobile numbers and direct dials, for teams that call.

Pros

• Headcount doesn't change the bill: unlimited users and exports at one price
• Records with a known age: 2,000+ researchers re-check human-verified contacts every 90 days, 95% accurate on SalesIntel's own figures
• Account research in the same place: intent and technographic data sit next to contacts

Cons

• You can't budget before a sales call: price on request only
• Part of the database ages on its own: the 90-day cycle covers human-verified records only

What users say: A reviewer invited by the vendor found some contacts over a year old, writing in a G2 review on the age of SalesIntel's data: "This can be quite cumbersome when some of the contact data is over a year old."

Pricing: No public prices; the page asks you to request pricing. Our SalesIntel pricing page collects the figures buyers have reported, so you can benchmark a quote.

SalesIntel lists no plans or prices, only a request form.

Skip it if you want to see a price, or start on a monthly plan, before you talk to sales; SalesIntel's pricing page shows neither.

Which contact database fits your team?

Match the tool to your budget, company size and target region: ZoomInfo for enterprise budgets selling into the US, Apollo.io for small teams that want value, Cognism for calling Europe, and FullEnrich for email and mobile accuracy across regions.

How does FullEnrich get verified emails and mobiles for your list?

FullEnrich is best overall for email and mobile accuracy across regions: a waterfall across 20+ providers, every result verified, billed only when found. The work happens in five steps:

1. Search your segment for free in FullEnrich Search, by persona or from a list of target accounts.
2. Run the people you keep through waterfall enrichment, where 20+ providers are asked in turn until a work email or mobile passes.
3. Each result is verified before you see it: three independent engines must agree on an email, and mobiles are checked for line type and active status.
4. You're billed only when something is found: 1 credit per email, 10 per mobile, nothing for misses or landlines.
5. The same steps run from the API, or from Claude and other AI agents through the FullEnrich MCP server.

The checks matter because sources disagree: in one customer's 500-contact comparison, FullEnrich and ZoomInfo both returned a mobile for 255 people, and the numbers matched 45% of the time.

Enriching every email in the 2,193-person search above costs at most 2,193 credits, about $121 at the 1,000-credit plan's rate of $0.055 a credit, and less when some aren't found, because misses are free.

Try it on your own list with 50 free credits, no card needed.

FAQ

What is the best B2B contact database right now?

The best B2B contact database depends on your budget, company size and target region: ZoomInfo for enterprise scale, Apollo.io for SMB value, Cognism for EMEA and mobile data, and FullEnrich for email and mobile accuracy across regions. Vendor claims conflict, so run the same people through your top two and count what verifies.

Are there free B2B contact databases?

Yes: Apollo.io, Lusha, ZoomInfo Lite, Seamless.AI and RocketReach all have free tiers, and FullEnrich has a 50-credit trial with no card. Apollo grants 900 credits per seat a year, Lusha 40 a month, ZoomInfo Lite 10, Seamless.AI 50 that don't replenish, and RocketReach 5 lookups. That covers a segment test.

Which B2B contact database is the most accurate?

Accuracy depends on region, seniority and segment, so no single provider's own data wins everywhere. FullEnrich is best overall for email and mobile accuracy across regions: it runs a waterfall across 20+ providers and verifies every result. Measure bounces and wrong numbers on your own list; vendors' own figures disagree, and Apollo's pages cite both 98% and 91% email accuracy.

How fast does B2B contact data go stale?

About 5% of one US sales-leader list changed jobs within 90 days: in a FullEnrich Search of 2,193 US software sales leaders (October 2026), 106 had moved, counting only detected moves. Vendor refresh clocks run from 30 days (Cognism) to 3 to 6 months (Lead411), so re-check a list before each campaign.

What's the difference between a contact database and enrichment?

A contact database helps you find people you don't have yet: you search by role, company and region. Enrichment starts from people you already have, such as a name and company, a LinkedIn URL or an email, and adds contact details. FullEnrich pairs people search with waterfall enrichment across 20+ providers.

Is using a B2B contact database GDPR-compliant?

Using a B2B contact database can be GDPR-compliant if you have a lawful basis, tell contacts where you got their data, and honor opt-outs. Ask each vendor where its data comes from and how it handles deletion requests. FullEnrich lists SOC 2 Type II and GDPR in its security section and stores no contact data.
