10 Best B2B Email Finders in 2026 (Tested)

1. Hunter: Best for finding emails from a company domain

What it does: Finds and verifies professional email addresses by domain or by name, with a B2B database, cold email sequences and an API. Best for: Founders and small sales teams who have a list of company websites and need the people's emails.

Hunter's Domain Search is the classic way to see which email addresses a company uses and the pattern behind them. Its Email Finder takes a name plus a domain, and if it can't find the address, the search is free. Every plan includes unlimited team members.

Key features

• Domain Search: lists the email addresses found for a domain, 1 credit per email (or up to 10 emails per credit in bulk).
• Email Finder: name plus domain in, most likely address out, with no charge if nothing is found.
• Email Verifier: 0.5 credit per address checked.
• Sequences: cold email from 1 connected inbox on Free and 3 on Starter.

Pros and cons

• ✅ Free plan with 50 credits a month
• ✅ No charge for searches that find nothing
• ✅ Unlimited users on every plan
• ❌ Thin coverage for small and new companies, according to reviewers
• ❌ Credits on monthly plans reset and don't roll over
• ❌ Reviewers find the free plan limited once a team grows

What users say

"The main place Hunter could improve is the depth of data for some smaller companies." (verified reviewer, G2)

Another reviewer summed up the cost side: "It can get expensive for bulk use, there are some data gaps depending on the industry, and CRM integrations are a little lacking." (Austin A., G2)

Pricing

• Free: $0, 50 credits a month
• Starter: $49 a month, or $34 a month billed yearly ($408 a year), 2,000 credits a month
• Growth: $149 a month, or $104 billed yearly, 10,000 credits a month
• Scale: $299 a month, or $209 billed yearly, 25,000 credits a month
• API only: 1,000 search credits for $50

That's about 1.7 cents per email on Starter billed yearly. From the Hunter pricing page, checked November 4, 2026.

Bottom line

Pick Hunter if your list starts with company domains and you want a simple, cheap finder your whole team can share. Skip it if you mostly sell to startups or small local firms, where its coverage is thinner.

2. Apollo.io: Best for email finding plus outreach in one app

What it does: A sales platform with a B2B contact database, Chrome extension, sequences and dialer, where revealing an email costs 1 credit. Best for: Small sales teams who want to find, verify and email prospects without stitching three tools together.

Apollo's free plan is a strong starting point if you also want outreach: 900 credits a seat a year, the Chrome extension and 2 sequences. Paid plans add unlimited sequences and much bigger credit pools. The trade-off reviewers mention most is data freshness, so verify before big sends.

Key features

• Contact database search, with advanced filters from the Basic plan.
• Chrome extension for LinkedIn, Gmail and Salesforce on every plan.
• Sequences: 2 on Free, unlimited from Basic.
• Waterfall enrichment on paid plans when Apollo's own email is missing.

Pros and cons

• ✅ Free plan with 900 credits a seat a year
• ✅ An email costs 1 credit, about 2 cents on Basic billed yearly
• ✅ Finding and sending in one tool
• ❌ Mobile numbers cost 8 credits each
• ❌ Reviewers report outdated contact records (225 mentions in G2's summary)
• ❌ Per-seat pricing adds up as the team grows

What users say

"What I like best about Appolo.io is that it combines prospecting, contact data, and email outreach in one platform." (Kuladeep P., G2)

"I dislike the trial being so short. The monthly costs are too expensive on the basic membership." (Kevin B., G2)

Pricing

• Free: $0, 900 credits per seat per year
• Basic: $49 per seat per month billed yearly, 30,000 credits per seat per year
• Professional: $79 per seat per month billed yearly, 48,000 credits per seat per year
• Organization: $119 per seat per month billed yearly, at least 3 seats

Yearly billing saves 24%. From the Apollo pricing page, checked November 4, 2026.

Bottom line

Pick Apollo if you want one app to find emails and send the first sequence this week. Skip it if you only need emails for another outreach tool you already pay for.

3. Findymail: Best for verified emails with a bounce guarantee

What it does: Finds and verifies B2B emails (and non-EU mobile numbers) by name, LinkedIn profile or CSV, with an API, MCP server and Clay integration. Best for: Outbound agencies and teams sending at volume, where every bounce hurts deliverability.

Findymail's pitch is a guarantee: if your bounce rate with its emails goes above 5%, it refunds the credits. It also verifies catch-all addresses that other tools mark as risky, and it doesn't charge when it can't find an email. Its prospecting plans use "generous usage" limits instead of credits, from $99 a month for one seat.

Key features

• Bounce guarantee: under 5% or your credits back.
• Catch-all verification for addresses other tools leave as "risky".
• Bulk finder: upload names and companies, get verified emails back.
• Integrations with Clay, HubSpot, Salesforce, Instantly, Lemlist and Pipedrive, plus API and MCP access.

Pros and cons

• ✅ Pay only for verified results
• ✅ Credits roll over up to twice your monthly allowance on credit plans
• ✅ No extra charge for emails you found in the last 30 days
• ❌ Starts at $99 a month, the highest entry price on this list
• ❌ Mobile numbers are non-EU only and cost 10 credits each
• ❌ Usage limits on prospecting plans run on rolling 5-hour and 7-day windows, which is harder to plan around

What users say

"I send 7m cold emails per month and tested over a dozen email finders. Findymail is the best email finder out there." (Kevin Y., G2)

"Not really cheap and credits only roll over 2x the monthly subscription." (Simon M., G2)

Pricing

• Individual: $99 a month, 1 seat, usage measured over rolling windows
• Team: $399 a month, 5 seats, 5 times the usage
• Scale: $999 a month, 20 seats, 20 times the usage
• Credit plan (for resellers and data teams): $99 a month for 5,000 finder credits plus 5,000 verifier credits; 1 email = 1 credit, 1 phone = 10

Yearly billing gives 2 months free. From the Findymail pricing page, checked November 4, 2026.

Bottom line

Pick Findymail if you send thousands of cold emails and a bounce costs you more than a credit. Skip it if you need a handful of emails a month: $99 is a lot for that.

4. Prospeo: Best free plan for verified emails

What it does: A B2B people and company database with an email finder, mobile finder, Chrome extension, CSV and API enrichment. Best for: Agencies and growth teams who enrich large lists, often from Sales Navigator or Clay.

Prospeo's free plan gives 100 credits a month with no time limit, the most of any free tier here, and one credit is one verified email (no email found, no charge). Paid plans start at $37 a month billed yearly for 2,000 credits a month, and extra credits cost from $10 per 1,000. Searching and previewing are free, so you only spend credits on the contacts you export.

Key features

• Free search and preview, credits only on export.
• Verified emails at 1 credit and mobile numbers at 10.
• Chrome extension for LinkedIn and Sales Navigator.
• CSV and API enrichment from Starter, HubSpot and Salesforce sync from Growth.

Pros and cons

• ✅ Free plan with 100 credits a month, no time limit
• ✅ Under 2 cents per email on Starter billed yearly
• ✅ Credit add-ons from $10 per 1,000
• ❌ Credits don't roll over
• ❌ Bulk email finding needs company domains, per one reviewer
• ❌ Price is per user, so teams multiply the bill

What users say

"Amazing data coverage and accuracy. Best on the market." (Felix F., G2)

From a 2-star review: "I could not bulk find email addresses without the company domain." (Brock S., G2)

Pricing

• Free: $0, 100 credits a month
• Starter: $49 a month, or $37 a month billed yearly ($441 a year), 2,000 credits a month
• Growth: $99 a month, or $74 billed yearly, 5,000 credits a month
• Pro: $249 a month, or $187 billed yearly, 15,000 credits a month

Prices are per user. From the Prospeo pricing page, checked November 4, 2026.

Bottom line

Pick Prospeo if you want to test on 100 real contacts a month for free, then pay under 2 cents per email. Skip it if your input is company names without domains.

5. Snov.io: Best for email finding plus cold email campaigns

What it does: An email finder, verifier and multichannel outreach tool with warm-up, a CRM and LinkedIn automation. Best for: Small teams and freelancers who want to find emails and run campaigns from one cheap account.

Snov.io bundles finding, verifying and sending, with unlimited team seats on every paid plan. Credits pay for prospect searches, email searches and verifications (1 credit each), and "recipients" pay for outreach. The free Trial plan renews every month with 50 credits, but it leaves out the API, bulk search and export.

Key features

• Email Finder and LinkedIn Prospect Finder extensions, plus bulk prospect and company search.
• 7-tier email verification with bounce risk detection.
• Campaigns with unlimited follow-ups and warm-up.
• API, webhooks and MCP access on paid plans.

Pros and cons

• ✅ Unlimited team seats
• ✅ Finding, verification, warm-up and sending in one plan
• ✅ Free Trial plan that renews monthly
• ❌ LinkedIn automation costs $69 a month per slot on top
• ❌ Trial excludes API, bulk search and export
• ❌ Reviewers say email accuracy varies

What users say

"It makes prospecting quick and simple. Easy to find verified emails and reach out without a lot of setup." (verified reviewer, G2)

"Email accuracy can be hit or miss sometimes and the interface can feel a bit cluttered when you are doing a lot at once." (verified reviewer, G2)

Pricing

• Trial: $0, 50 credits and 100 recipients a month
• Starter: $39 a month, or $29.25 a month billed yearly, 1,000 credits and 5,000 recipients
• Pro: from $74.25 a month billed yearly, 5,000 credits and 25,000 recipients

Yearly billing saves 25%. From the Snov.io pricing page, checked November 4, 2026.

Bottom line

Pick Snov.io if you want one inexpensive tool to find emails and send campaigns with a small team. Skip it if you need the lowest cost per email: at about 3 cents on Starter billed yearly, it's above Hunter and Prospeo.

6. FullEnrich: Best for waterfall search across 25+ sources

What it does: Sends each contact through 25+ data providers until one returns a verified work email or mobile number. Best for: Teams with a list of named prospects who want the highest odds of a working address.

FullEnrich asks 25+ vendors in turn for each contact and charges only when one returns verified data. It prices a work email at 1 credit, a personal email at 3 and a mobile at 10, with the Pro plan at $55 a month for 1,000 credits.

• ✅ Credits roll over 3 months on monthly plans
• ❌ About 5.5 cents per email, more than double the database tools
• ❌ Mobiles cost 10 times more than emails
• ❌ Reviewers report slow runs and empty results

What users say

"The enrichment process can be quite slow at times, and there are many instances where it fails to find any data at all." (Afrah A., G2)

"Great data quality, and the app is easy to use without being complicated." (verified reviewer, G2)

Pricing

• Free trial: 50 credits
• Pro: $55 a month billed monthly for 1,000 credits at the default setting; larger packs lower the price per credit
• Enterprise: custom

From the FullEnrich pricing page, checked November 4, 2026.

Bottom line

Pick FullEnrich when one database keeps coming back empty and you'd pay more per email to find it. Skip it if price per email is your main constraint.

7. RocketReach: Best for unlimited lookups on a yearly plan

What it does: A search engine for 700 million professionals and 60 million companies, with verified work and personal emails and, on Pro, phone numbers. Best for: Recruiters, PR people and sellers who look up many individual contacts.

RocketReach's yearly plans have unlimited email lookups; the limit that counts is exports, from 1,200 a year on Essentials. Monthly plans cap lookups at 100, 250 or 1,000 a month. It returns personal emails as well as work ones, which suits recruiting more than cold sales.

Key features

• Unlimited lookups on yearly plans (RocketReach links an FAQ on what "unlimited" covers).
• Work and personal emails, plus mobile and direct phones on Pro and Ultimate.
• MCP and API access on every paid plan.
• Technographics, news and org charts on Pro.

Pros and cons

• ✅ Unlimited lookups on yearly billing

• ✅ Personal emails for hard-to-reach people
• ❌ Export limits (1,200 a year on Essentials) cap bulk use
• ❌ Phone numbers need Pro at $899 a year
• ❌ Reviewers report outdated contacts (111 mentions in G2's summary)

What users say

"I appreciate that RocketReach usually has valid emails when other services don't." (Cozette L., G2)

Pricing

• Free: 5 lookups
• Essentials (email only): $399 a year ($33 a month), 1,200 exports a year

• Teams: from $6,000 a year

From the RocketReach pricing page, checked November 4, 2026.

Bottom line

Pick RocketReach if you look up people one at a time and want no lookup cap. Skip it if you need to export tens of thousands of contacts.

8. Lusha: Best for emails plus direct phone numbers

What it does: A B2B contact database with verified emails and phone numbers, used in a Chrome extension on LinkedIn, CRMs and any website. Best for: Reps who call as well as email and want both from one click.

Lusha costs more per email than the cheap finders, but a phone number is 5 credits where most tools here charge 8 to 10. Its extension works on LinkedIn, inside CRMs and on company websites, and the Pro plan adds the API and CSV enrichment.

Key features

• Chrome extension on LinkedIn, CRMs, Gmail and any website.
• Verified emails (1 credit) and phones (5 credits).
• Bulk enrichment from Starter and CSV enrichment from Pro.
• CRM export to HubSpot and Salesforce.

Pros and cons

• ✅ Free plan with 40 credits a month
• ✅ Phones at 5 credits, cheaper than most tools here
• ✅ Monthly credits roll over on Pro and Premium (up to twice the cap)
• ❌ About 9 cents per email on Starter billed yearly
• ❌ API needs Pro or higher for normal rate limits
• ❌ Reviewers report weaker coverage in some regions

What users say

"I use Lusha mostly for finding customer data, especially phone numbers and email addresses, and it does a really good job at that." (Anil K., G2)

"Lusha's database is strong for large companies and mainstream industries." The reviewer filed that under "Limited Data Coverage for Niche Markets". (verified reviewer, G2)

Pricing

• Free: $0, 40 credits a month
• Starter: $37.45 a month billed yearly, 4,800 credits a year
• Pro: $52.45 a month billed yearly, 7,200 credits a year
• Premium: $299.95 a month billed yearly, 40,800 credits a year

Figures at the page's default credit setting; yearly billing saves 25%. From the Lusha pricing page, checked November 4, 2026.

Bottom line

Pick Lusha if you want a phone number next to every email. Skip it if email is all you need, because the cheaper finders above do that for a fraction of the cost.

9. Kaspr: Best for contact details on LinkedIn profiles

What it does: A Chrome extension that shows emails and phone numbers on LinkedIn, Sales Navigator and Recruiter Lite profiles, with lists and CRM export. Best for: Sellers and recruiters who prospect inside LinkedIn all day.

Kaspr's paid plans include unlimited B2B email credits (under a fair-use policy), so the limits that bite are phone credits and exports. Starter gives 1,200 phone credits and 12,000 exports a year, and the pricing page lists prices in euros, pounds and dollars.

Key features

• LinkedIn extension that works on profiles, groups and events.
• Sales Navigator support from Starter and Recruiter Lite from Business.
• CSV enrichment from LinkedIn URLs.
• Integrations with HubSpot, Salesforce, dialers and Zapier.

Pros and cons

• ✅ Unlimited B2B emails on paid plans (fair use)
• ✅ Free plan with 15 email and 5 phone credits a month
• ✅ Shared credits across the team

• ❌ Bulk work depends on LinkedIn URLs
• ❌ Reviewers say credits run out fast at high volume

What users say

"This extension is simple to use on Chrome and makes it easy to extract data from LinkedIn." (verified reviewer, G2)

"One drawback is that the credit system depletes rapidly when engaging in high volume sourcing." (Dev S., G2)

Pricing

• Free: $0, 15 B2B email credits, 5 phone credits and 5 direct email credits a month
• Starter: $49 per user a month billed yearly, or $65 monthly; unlimited B2B emails, 1,200 phone credits a year
• Business: $79 per user a month billed yearly, or $99 monthly; 2,400 phone credits a year
• Enterprise: custom

From the Kaspr pricing page, checked November 4, 2026.

Bottom line

Pick Kaspr if your prospecting happens on LinkedIn and you want the email on the profile you're looking at. Skip it if you work from domain lists or CSVs without LinkedIn URLs.

10. Dropcontact: Best for GDPR-first email enrichment in Europe

What it does: Finds and verifies B2B emails from names and companies, then cleans and enriches CRM records, with processing it describes as "100% GDPR-compliant". Best for: European companies whose data protection officer wants to know where every email came from.

Dropcontact enriches the names and companies you upload with a verified email, and it re-credits every email it can't find. Plans are priced in euros, from €29 a month for 500 credits, and it has an API, MCP access and native CRM integrations for Pipedrive, Salesforce and HubSpot.

Key features

• Pay on success: emails not found go back to your balance.
• Catch-all verification and its own email validation.
• File, Google Sheets and API enrichment.
• CRM enrichment for Pipedrive, Salesforce and HubSpot (a separate subscription).

Pros and cons

• ✅ 50 free credits to test
• ✅ Credit carryover on Growth
• ✅ CRM cleanup (job titles, company names) on Growth
• ❌ No phone numbers
• ❌ No pay-as-you-go plan, per reviewers
• ❌ Email finder credits can't be used for CRM enrichment

What users say

"You receive verified contact information, mainly email, when you use Dropcontact. It is very accurate." (Jamie C., G2)

"Still a fair amount of individuals (~50%) end up without email addresses." (Max F., G2)

Pricing

• Free: 50 credits
• Starter: from €29 a month for 500 credits (€79 a month at the page's default of 4,000 credits)
• Growth: €120 a month at 4,000 credits
• Enterprise: custom, from 200,000 credits a month

Yearly billing saves 20%. From the Dropcontact pricing page, checked November 4, 2026.

Bottom line

Pick Dropcontact if you sell in Europe and GDPR questions slow every data purchase. Skip it if you need phone numbers: reviewers note it covers email and LinkedIn only.

How to choose the right B2B email finder

Start with what's in your spreadsheet. A column of domains, a column of LinkedIn URLs and a column of names plus companies each point to a different tool.

Choose Hunter if you: have company domains and want a cheap finder the whole team can use. Choose Apollo.io if you: want to find emails and send sequences from one app. Choose Findymail if you: send at volume and need a bounce guarantee. Choose Prospeo if you: want 100 free emails a month before you pay, then under 2 cents each. Choose Snov.io if you: want finding, warm-up and campaigns in one cheap plan. Choose FullEnrich if you: keep getting empty results from a single database. Choose RocketReach if you: look up people one by one and hate lookup caps. Choose Lusha if you: need phone numbers next to emails. Choose Kaspr if you: prospect inside LinkedIn and Sales Navigator. Choose Dropcontact if you: sell in Europe and want GDPR-first processing.

Here's what one email costs on each cheapest paid plan, from the prices above. I divided the plan price by its email credits, so it's a best case that assumes you use every credit:

Calculated from list prices checked November 4, 2026. RocketReach and Kaspr sell unlimited emails with export limits, so they don't fit this table.

If you're building a B2B email list from scratch, the cost per email decides the budget more than the plan price. For a narrow audience such as an IT decision makers email list, coverage of that niche counts for more, so test the free tiers on 20 of your real targets before you buy.

Skip the category if you need fewer than 20 emails a month: the free plans of Hunter, Prospeo and Apollo cover that.

Decide whom to look up before you pay per B2B email

Every finder above charges per email found, per export or per seat, so the list you feed it sets the bill. Upload a scraped list of 5,000 companies that mostly don't fit and you'll pay to find emails nobody should receive.

The cheaper move is to agree on who fits first. Sources like a B2B directory or a B2B data provider give you company lists by industry and size, and B2B intent data providers add which of those companies are researching your category right now.

I built Openlead for that step. Describe your ideal customer in Openlead in a sentence, and it finds up to 25 companies that fit, with 1 to 3 relevant people at each and their profile links. It has no email addresses or phone numbers, so you then run only the companies and people that fit through the email finder you picked.

Final verdict

Hunter is the simplest and cheapest place to start if you have domains, Prospeo has the biggest free plan, and Findymail is worth its higher entry price when bounces cost you deliverability. Add Lusha when you need phones and Dropcontact when GDPR is the question.
