Top 11 Hunter.io Alternatives To Transform Your Lead Gen and Outreach Processes

Finding the right people to pitch your product to has never been easier, thanks to the many lead gen platforms available today. For me, Hunter.io is undeniably one of the best email outreach tools. 

The platform lets you find, search, and verify email addresses. Equipped with intent data and various campaign tools, you can send targeted and timely emails your prospects will ACTUALLY want to read. It doesn’t have the biggest database (~100 million), but the data quality makes up for it.

While effective and user-friendly, Hunter.io may not be the right solution for everyone. Perhaps the pricing is too steep for your small-business budget, or you just want to see what else is out there—whatever the case, I’ve got you covered. I’ll introduce you to my top 10 picks of the best-rated Hunter.io alternatives

Stick around to the end as I’ll share a simple trick to help you expand your prospect list regardless of the platform you use (Hint: it takes a few minutes and is 100% FREE). 

How I Evaluated the Alternatives

To select viable alternatives to Hunter.io, I prioritized the following qualities:

  • Mostly positive reviews on reputable sites such as G2 and Capterra
  • A large database of verified and up-to-date contacts
  • A variety of features or a small number of well-executed features
  • Ease of use and onboarding
  • Pricing transparency and flexibility

I’ll give my uncensored opinion on each platform, presenting both its advantages and disadvantages. I’ll also share their pricing, but make sure to check out the official websites for the most current and accurate information.

Now, let’s see which platforms made the cut:

1. RB2B

RB2B stands out as a Hunter.io alternative by offering a fresh approach to email lead generation. Instead of relying on contact databases and email verification, RB2B identifies the actual individuals visiting your website in real time, not just the companies they represent. This makes it an invaluable tool for teams looking to enhance their email outreach.

Rather than spending hours scraping emails or guessing who to contact, RB2B delivers real-time data on interested visitors directly to Slack or Teams. This allows your sales team to act immediately with targeted email outreach based on visitor behavior.

By tracking specific pages visitors engage with, RB2B provides contextual insights, enabling your team to send personalized emails that speak directly to the prospect’s interests. This means fewer cold emails and more relevant, high-converting outreach.

RB2B simplifies prospecting with features like:

  • Person-Level Visitor Identification: Capture detailed information about site visitors, including names, job titles, emails, LinkedIn profiles, and company details.
  • Hot Leads Tagging: Prioritize the most engaged visitors who show signs of intent, ensuring your sales team focuses on high-value prospects.
  • Hot Pages Tracking: Identify the most visited pages on your site, helping you understand where visitors are showing the most interest.
  • Real-Time Alerts: Receive instant notifications for qualified leads directly in Slack, Teams, or your CRM, allowing for immediate follow-up.
  • CRM & Sales Tool Integrations: Seamlessly integrates with top CRMs and sales tools like Salesforce, HubSpot, and over 20 other platforms to streamline your workflow.
  • Compliance by Design: RB2B focuses exclusively on U.S.-based visitors and is fully CCPA/CPRA compliant (GDPR does not apply).

RB2B is the fastest way to surface high-intent leads. Unlike Hunter.io, which relies on manual email searches, RB2B tells you who’s already knocking on your door, so outreach feels warmer and more relevant. The biggest limitation is that coverage is U.S.-focused, so international traffic isn’t identified.

Pricing

  • Free Plan: Comes with 150 monthly credits and real-time LinkedIn profile notifications delivered straight to Slack.
  • Pro+ Plan ($129/month): Includes 300 monthly credits and all Free Plan features, plus advanced capabilities such as hot lead tracking, repeat visitor insights, powerful filtering, CSV exports, pageview history, and integrations with 20+ CRMs and marketing tools.
  • Custom Plan (Contact Sales): Designed for agencies and larger teams needing 2,000+ monthly credits, advanced customization, and dedicated support.

 All plans come with a 7-day free trial, and pricing is based on annual billing. Visit our pricing page to explore detailed plan comparisons.

Pros 

  • Identifies real people, not just companies, with verified names, roles, and LinkedIn profiles
  • Sends instant lead alerts to Slack or CRM for faster follow-up
  • Highlights high-intent prospects through Hot Leads and Hot Pages
  • Offers a free plan for easy, risk-free testing
  • Sets up in under five minutes with no developer help needed

Cons

  • Person-level data limited to U.S. visitors; global traffic available only at the company level

2. Snov.io 

Like Hunter.io, Snov.io is an all-in-one sales platform with a focus on email. It aims to simplify and automate as much of the sales process as possible, offering capabilities like:

  • Email finder and verifier to collect leads
  • AI conversation generator to warm leads
  • Simple sales CRM to streamline sales
  • Chrome extension for on-the-go prospecting
  • Numerous native integrations and API

If you’re an avid LinkedIn user like me, you’ll appreciate that Snov.io can scrape email addresses from profiles. You can even run email drip campaigns that trigger based on the leads’ platform activity.

Source: Snov.io

From my experience, Snov.io is reliable and successful in its attempt to make sales easy, even though the sheer number of features took some getting used to. It helps that the customer support is responsive and can help resolve any issues quickly

What I didn’t like was the pricing. Snov.io is less expensive than Hunter.io on paper, but the credit system isn’t the most balanced. The LinkedIn Automation feature is also charged separately.

Pricing

  • Trial: free
  • Starter: $39/month*
  • Pro (5,000 credits): $99/month
  • LinkedIn Automation add-on: $69/month/account
  • Managed Service: starting at $3,999/month

*All prices pertain to the yearly billing model

Pros 

  • Makes sales fast and easy
  • LinkedIn address indexing and integrated email campaigns
  • Many integration options
  • Great customer support

Cons

  • Steep learning curve
  • Complex pricing

3. Apollo

Apollo is a sales platform that offers many of the same benefits as Hunter.io, including contact search, outreach automation, and campaign analytics. However, Apollo has a ton more features in its arsenal, such as:

  • Lead scores and signals for qualification
  • Engagement automation that expands to phone calls and LinkedIn
  • Meeting and follow-up management
  • Conversation recording and analysis
  • Deal management with recommendations and insights

Another perk of choosing Apollo is the database, which is twice as large as Hunter.io’s (275 as opposed to 107 million contacts).

Source: Apollo

Unsurprisingly, all these features overwhelmed me at first. But once I got the hang of the platform, it became easy to use and a major time-saver. I love the fact that it can automate many of my mundane tasks, such as data enrichment and cleaning. 

As expected, the price reflects Apollo’s impressive scope. The number of mobile and export credits is limited, and it can get expensive to purchase more.

Pricing

  • Free
  • Basic: $49/user/month*
  • Professional: $79/user/month
  • Organization: $119/user/month


*All prices pertain to the yearly billing model

Pros

  • Comprehensive platform
  • Provides email addresses and phone numbers
  • 2x bigger database than Hunter.io’s
  • Many automation capabilities 

Cons

  • Steep learning curve
  • Limited number of credits

4. Cognism

Cognism, as a sales intelligence platform, is a solid Hunter.io alternative. While it lacks email campaign capabilities, it makes up for it by FOCUSING SOLELY on providing high-quality international B2B data.

Besides email addresses, Cognism can source phone numbers and intent data. To ensure the info is correct and up-to-date, it uses a verification system that combines AI and human input. It even checks Do Not Call lists in several European countries, which is rare. 

Source: Cognism

The platform is intuitive and could be integrated seamlessly into my workflow thanks to the:

  • Browser extension that lets you prospect on CRMs, LinkedIn, and corporate websites
  • Zapier integration that lets you connect any CRM or email marketing tool

Besides occasional outdated info (that most platforms face, TBH), the only real negatives are the contact enhancing and exporting limit and the small number of pre-built integrations.

While not transparent about the costs, Cognism offers flexible licenses with unrestricted access options.

Pricing

  • Custom pricing, available upon request

Pros

  • Verified global B2B contact information
  • Intent data and auto-enrichment
  • Browser extension
  • Intuitive platform
  • Flexible, custom plans

Cons

  • Pricing not publicly available
  • Few native integrations
  • Limit for contact enhancing and exporting

5. UpLead

Like Cognism, UpLead can’t boast a large set of functionalities—but it prioritizes data quality instead. The features it does offer are highly useful. I particularly enjoyed the advanced search that includes over 50 filters. The platform also offers:

  • Email, phone, intent, and technographic data
  • Data enrichment with 50+ data points
  • Various integration options and API

UpLead’s database is larger than Hunter.io’s, counting over 155 million contacts and 14 million business profiles.

Source: UpLead

What truly impresses me is UpLead’s dedication to ensuring data quality. The platform verifies contacts as you search them and even discloses the degrees of confidence. The best part—UpLead will refund you for any bounces and data inaccuracies!

I found the platform user-friendly and frictionless, but it’s worth noting that some users have reported technical issues. On the upside, there’s 24/7 customer support to help you in case you run into issues yourself.

Pricing

  • Free 7-day trial
  • Essentials: $74/month
  • Plus: $149/month
  • Professional: Custom pricing

*All prices pertain to the yearly billing model

Pros 

  • Advanced search with 50+ filters
  • Larger database than Hunter.io’s
  • Refund for inaccurate contacts
  • Many integration options
  • 24/7 customer support

Cons

  • Technical issues

6. Clearbit 

Clearbit is a B2B data provider that was recently acquired by HubSpot. I believe this partnership has the potential to elevate this somewhat modest platform to new heights, but that remains to be seen.

One of my favorite things about Clearbit is its advanced company analysis and granular categorization. You can also create a custom standardized set of roles for easier ICP-matching. Other features include:

  • Lead scoring and sales rep routing
  • ICP matching and buying intent data
  • Browser extension to find email addresses as you browse
  • Additional free tools, such as the TAM calculator

Clearbit’s database is half the size of Hunter.io’s (~50 million), but it does have global coverage, and I found the email addresses to be generally up-to-date.

Source: Clearbit

I like the platform’s simple and intuitive UI and the fact that it has an API for third-party integrations. What I don’t like is that they aren’t open about the pricing. Like other users, I also think the credit system is unbalanced—I depleted mine in no time.

Pricing

  • Free version
  • For paid tiers, the pricing is available upon request

Pros

  • B2B email addresses
  • Buying intent data
  • Granular title categorization
  • Free browser extension
  • Accurate data with global coverage
  • User-friendly

Cons

  • Smaller database than Hunter.io’s
  • Non-transparent pricing
  • Limited credits

7. Instantly 

Instantly has chosen an appropriate name—they’ve done everything in their power to accelerate and streamline the sales process. For example, the platform has an automated email deliverability network tool and even one-click bulk domain testing for list cleaning. Other features I liked include:

  • Personalized email campaign builder 
  • Zapier integration to automate outreach
  • Unibox multi-inbox manager
  • Advanced campaign analytics 
  • Resources and community support

Much like its feature offering, Instantly’s database is huge, boasting over 280 million contacts. The validation seems to be solid, as most of the data I’ve received was excellent.

Source: Instantly

Instantly is easy to navigate despite some minor bugs. It also has great customer support, especially if you’re on the Hypergrowth/leads plan or up. 

The only gripe I have with Instantly is its cost. The basic plans are limited, and you have to pay separate subscriptions for leads and outreach.

Pricing

Sending & Warmup:

  • Growth: $30/month*
  • Hypergrowth: $77.6/month
  • Light Speed: $286.3/month
  • Enterprise: Custom

Leads:

  • Growth Leads: $42.3/month
  • Supersonic Leads: $87.3/month
  • Hyperleads: $177.3/month
  • Enterprise: Custom

*All prices pertain to the yearly billing model

Pros

  • Sales and CRM platform with automation
  • Campaign builder
  • Inbox manager
  • Bigger database than Hunter.io’s
  • Easy to use

Cons

  • Minor glitches
  • High and inflexible pricing
  • Plan limits

8. ZoomInfo 

ZoomInfo is likely the best-known B2B sales platform out there. It’s an all-in-one operating system suitable for sales, marketing, Ops, and HR teams. The sheer number of features it provides is INSANE. Here are some of my favorites:

  • Website visitor tracking
  • Sales cadence automation
  • Conversation intelligence and evaluation
  • Chrome extension
  • Numerous integration options

I can safely say that ZoomInfo’s database is among the best available. It counts over 250 million profiles, and, drawing from collective experience, the data is mostly reliable.

Source: ZoomInfo

ZoomInfo’s comprehensiveness comes at the expense of usability, though. The UI is overwhelming, and the learning curve is steep. 

The pricing is what bugs me the most, though. The platform is outright unaffordable for small businesses, often reaching into the tens of thousands.

Pricing

  • Available upon request

Pros 

  • All-in-one, multi-use platform
  • Sales automation across the board
  • Conversation intelligence
  • Large and reliable database
  • Integrates with numerous tools

Cons

  • Steep learning curve
  • Pricing publicly unavailable
  • Too expensive for small businesses

9. VoilaNorbert

VoilaNorbert is a simple email finder that combines real-time search with its database of over 100 million prospects. Despite a few bounces, I found its data quality satisfactory, and I applaud it for providing certainty scores for results.

Besides prospecting, VoilaNorbert offers the following features:

  • Single and bulk lookup
  • Email sequences to automate and scale your outreach
  • Chrome extension to find addresses on LinkedIn and other websites
  • Integrations, including Zapier

I enjoyed VoilaNorbert’s clear, no-frills interface, the platform required virtually no setup. 

Source: VoilaNorbert

The pricing is flexible and fair, allowing you to purchase additional credits if you run out. Besides being free for up to 2,500 monthly emails and 1,000 active leads, the platform won’t charge you if it doesn’t find an email.

Pricing

Prospecting:

  1. Valet: $39/month
  2. Butler: $79/month
  3. Advisor: $199/month
  4. Counselor: $399/month

Sequences:

  1. Starter: $19/user/month
  2. Teams: $59/user/month
  3. Scale: $99/user/month

*All prices pertain to the yearly billing model

Pros

  • Simple email finder with good accuracy
  • Email sequence automation
  • Doesn’t charge for empty searches
  • Extremely easy to use and set up
  • Free trial

Cons

  • Limited features
  • Occasional bounces

10. RocketReach

RocketReach is a sales and recruiting intelligence platform with a database of a whopping 700 million profiles. While I find its claim of being the most accurate platform a reach, I was generally pleased with its data quality. Among my favorite features are:

  • Advanced search (with LinkedIn scraping)
  • AI-powered prospect recommendations
  • Automatic list building and updating
  • Integrated email automation 
  • Browser extension, integrations, and API

Source: RocketReach

I had no problems setting up or learning to use the platform, though I must admit it isn’t that pleasing to the eye. Other reviewers reported technical difficulties, especially with exporting and integrations.

The pricing is where RocketReach misses the mark. It’s expensive, arguably even inaccessible for up-and-coming businesses, and charges for each user separately.

Pricing

Individual plans:

  1. Essentials: $27/month*
  2. Pro: $69/month
  3. Ultimate: $175/month

Team plans:

  1. Team Pro: $83/user/month
  2. Team Ultimate: $207/user/month
  3. Custom

*All prices pertain to the yearly billing model

Pros 

  • Database of over 700 million profiles
  • Great selection of features
  • LinkedIn email search
  • Built-in email outreach

Cons

  • Technical issues
  • Highly-priced

11. Lusha

With Lusha, you can fetch global B2B contact and intent data with ease. You can use the advanced filters to build lists, enrich them in one click, and then score and route them. Among other useful features are:

  • Browser extension to prospect on any website
  • ICP insights based on past searches
  • Direct email sequences built into the platform
  • CRM data enrichment and API integration 

Lusha’s database counts around 45 million contacts and, like any other platform, occasionally delivers outdated info.

Source: Lusha

I found the setup quick and painless and the overall platform intuitive. When I first tried Lusha, I remember being annoyed by the extension pop-up, but I’m happy to report that a new version has since come out.

Still, I’ll let you decide whether these benefits justify Lusha’s cost.

Pricing

  • Free
  • Pro: $22.45/month/user
  • Premium: $52.45/month/user
  • Scale: Custom

*All prices pertain to the yearly billing model

Pros

  • B2B contact and intent data
  • One-click CRM data enrichment
  • Built-in email outreach
  • ICP insights and analytics
  • Easy to implement and use

Cons

  • Relatively small database

Final Thoughts

And if Snov.io doesn’t meet your needs or budget, there’s a world of other features you can explore.
