What makes a good email finder tool?
In short: The best tool returns verified emails, plugs into your CRM, and holds up on large lists without hurting deliverability.
We evaluated these tools based on their ability to solve key sales needs. A good email finder tool contains the following features:
- High accuracy and built-in verification: Consistently deliver valid, verified emails without manual checking
- CRM sync: Automatically push verified emails to Salesforce, HubSpot, and other CRMs
- Flexible search options: Support both single-profile lookups for targeted outreach and bulk searches for scaling your prospecting process
- Compliance and privacy: Follow GDPR, CCPA, and platform guidelines, and provide verification to protect sender reputation
How we tested and ranked these tools
When selecting the best email finders to include in this list, we put each through real-world outbound workflows to enrich contact data with contact details and verify emails for cold outreach campaigns.
We looked at success rates, CRM integrations, and reliability at scale, while also considering honest user feedback from G2 and Capterra (as of October 2025).
The best email finder tools, ranked and reviewed
1. PhantomBuster – best for waterfall email enrichment
- ⭐️ G2: 4.4/5
- ⭐️ Capterra: 4.5/5
- Verified match rate: 72% (n=1,000 LinkedIn profiles, tested August 2025)
PhantomBuster integrates email discovery into your workflow. It collects publicly shared emails from profiles when available and automatically falls back to built-in providers (e.g., Dropcontact, Hunter, Icypeas) for verification—all inside PhantomBuster.
Here’s how PhantomBuster’s waterfall enrichment works:
- LinkedIn profile collection: If a contact lists an email publicly, PhantomBuster can capture it and verify it via integrated enrichers. Always follow LinkedIn’s guidelines
- Icypeas: Used automatically if an email isn’t available on LinkedIn
- Dropcontact: Engaged if Icypeas doesn’t find an email
- Connect your own provider: Link your Hunter or Snov.io account via API to use your own credits
Setup experience
PhantomBuster lets you set a waterfall: check the profile, then run built-in enrichers, or connect your own provider via API so you control cost and accuracy.
If you’re using PhantomBuster credits, enrichment through Dropcontact is automatically included, saving you time and extra costs.
By default, the automation checks the profile for a publicly listed email, then runs enrichment if none is present. Each email enrichment through Icypeas or Dropcontact consumes one PhantomBuster credit per email. If you connect your own provider accounts, PhantomBuster won’t use platform credits. You choose the most cost-effective route.
Our findings when testing each enrichment provider (August 2025, n=1,000):
| Tool | Success rate | Verification | Execution time |
| 47% | None | ~2 mins per lead | |
| Hunter | 68% | 97% | ~1 sec per lead |
| Dropcontact | 72% | 100% | ~8 secs per lead |
| Snov.io | 31% | None | ~2 secs per lead |
| Hunter + Dropcontact | 73% | 97–100% | ~3 secs per lead |
What to know: If you aim for the best combination of speed and verified accuracy, Hunter + Dropcontact delivers top results, validating emails in ~3 seconds per lead in our August 2025 test (n=1,000).
Alternatively, you can integrate your own Hunter.io or Dropcontact subscription. With this approach, PhantomBuster does not use any credits, giving you greater flexibility based on your budget and resources.
What makes PhantomBuster stand out
Compared to other email finders, PhantomBuster delivers a high verified success rate, especially when using its built-in waterfall enrichment (LinkedIn → Icypeas → Dropcontact).
Tools like Apollo often face criticism for lower accuracy, especially when sourcing emails at scale from LinkedIn.
| Tool | Success Rate | Verification | Execution Time | |
| 47% | None | ~2 mins per lead | ||
| Hunter | 68% | 97% | ~1 sec per lead | |
| Dropcontact | 72% | 100% | ~8 secs per lead | |
| Snov.io | 31% | None | ~2 secs per lead | |
| Hunter + Dropcontact | 73% | 97–100% | ~3 secs per lead |
PhantomBuster features that help with email finding

- CRM integration: Sync enriched data with HubSpot and other CRMs to keep your sales pipeline accurate and up-to-date without manual entry
- Chrome extension: Use PhantomBuster’s Chrome extension to surface verified contact info from your connected providers while you browse profiles, then save to PhantomBuster or HubSpot—within platform limits
What users are saying
“Saved hours building lead lists; easy sync with Google Sheets.” – Emma, G. G2 review
“I like the fact that the phantom is a simple and efficient building block that you can set up in minutes to get started. PhantomBuster really shines as a building block in our automation scenarios, or to automate ad-hoc enrichment/engagement tasks.” – Philippe, B, G2 review
“Follow platform limits to protect your account.” – Rick, H. Capterra review
Pros and cons
PhantomBuster is a strong pick for sales teams needing fast, compliant LinkedIn automations with real-time enrichment and no coding.
| Pros | Cons |
| ✅ Data-compliant email collection and verification | ❌ Chrome extension in early access as of October 2025 |
| ✅ Waterfall enrichment to improve match rates | ❌ Pricing may be high for solo business owners |
| ✅ Export CSVs, and sync records with HubSpot |
Pricing
| Plan | Features | Price |
| Free trial | 50 email credits for 14 days | $0 |
| Starter | 500 email credits/month | $69 |
| Pro | 2,500 email credits/month | $159 |
| Team | 10,000 email credits/month | $439 |
Final take: Is PhantomBuster good for email finding?
Yes, it’s one of the top choices if you’re sourcing leads directly from LinkedIn or Sales Navigator. PhantomBuster’s no-code setup makes it easy to collect and enrich emails without manual work, even for non-technical users. It’s a good fit when:
- You want to automate lead generation on LinkedIn or Sales Navigator
- You work in SaaS, B2B, or agency sales
- You use HubSpot, Salesforce, or Google Sheets
- You value speed, personalization, and control over your outbound pipeline
2. GetProspect: best for quick bulk email enrichment with integrated list management
- ⭐️ G2: 4.0/5
- ⭐️ Capterra: 4.4/5
GetProspect works best when you already have a list and need fast enrichment. Unlike PhantomBuster, which sources profiles and enriches contact data in near real time through integrated providers, GetProspect works in reverse. You upload a CSV file with names, domains, or company info, and it fills in verified emails using its 200M+ contact database.
You can also manually search for contacts by name and company if you’re working on smaller, more targeted campaigns. Processes ~2,000 rows in minutes; best when you prioritize scale over hyper-targeting.
Setup experience
GetProspect quickly enriches uploaded lists by populating emails from its extensive database. While this allows immediate access to emails, accuracy may vary since these are database-driven results rather than real-time verifications.
If you’re enriching large lists (e.g., 2,000+ contacts), expect rapid results but consider verifying emails independently for maximum accuracy.
Standout features that help with email finding
- Bulk email finder by uploading a CSV or manually inputting individual leads (name and company or domain) to pull verified emails instantly from its extensive internal database
- Built-in lead management system for segmenting contacts
- Built-in email verification to reduce bounce rates
- Integrations with HubSpot, Pipedrive, and popular CRMs are available only on the $99/month (and higher) plans
What users are saying
“We have been able to target accounts and industries quickly and efficiently with GetProspect properly.” – Geoff, P, Capterra review
“Sometimes, when you are saving 100s of leads, the website acts weird. Another issue is that even the valid emails will have a 5% bounce rate, so take that with a grain of salt. I got banned by LinkedIn when I was using the GetProspect extension for LinkedIn, so beware.” – Raj, L, G2 review
Pros and cons
| Pros | Cons |
| ✅ Great for building large outbound prospect lists | ❌ No outreach or sequencing tools built in |
| ✅ Straightforward CRM integrations | ❌ Email accuracy is based on database updates |
Pricing
| Plan | Features | Pricing |
| Free | 50 valid emails (renewable monthly), LinkedIn extension | $0/mo |
| Starter | 1,000 valid emails, Zapier integration, priority live-chat support | $49/mo |
| Growth | 5,000 valid emails, native integration | $99/mo |
Final take: Is GetProspect good for finding email addresses?
If speed and scale matter most, GetProspect delivers. It’s built for high-volume prospecting with fast CSV uploads and bulk enrichment. In our tests, it returned verified emails in seconds. That said, its static database means accuracy can dip, especially for niche roles or smaller companies. You may need to verify results post-export, but for sheer volume, it holds up.
3. Apollo: best for combining email discovery with sales engagement
- ⭐️ G2: 4.7/5
- ⭐️ Capterra: 4.6/5
Apollo combines email discovery and engagement in one platform with a large B2B database (vendor-reported). With access to over 275 million contacts and 73 million companies (vendor-reported), Apollo helps you discover verified email addresses and qualify and reach out to prospects within the same platform. You can search contacts by job title, company, industry, and more, then instantly pull email addresses from its database.
It also includes a Chrome extension to find emails while browsing LinkedIn, and built-in outreach tools like sequencing, calling, and task automation. Since it relies entirely on its internal database, email accuracy can vary, especially for niche industries or fast-changing teams.
Setup experience
After signing up, you can find verified emails through the prospecting dashboard directly from their extensive contact database. The UI is polished and built for sales reps. The filters are clear; you can enrich contacts, save them to lists, and sync to your CRM in just a few clicks.
Standout features that help with email finding
- Massive B2B contact database (275M+ contacts, 30+ filters, vendor-reported)
- Chrome extension to find and save emails from Apollo’s database
- Built-in email verification to improve accuracy and reduce bounce rates
- One-click CRM sync with HubSpot and Salesforce (as of October 2025)
What users are saying
“I just had to type a certain person’s name, and there you go – all the details were at my disposal.” – Anand, T. G2 review
“The most significant issue is data accuracy; despite the size of the database, I frequently encounter outdated or incorrect contact information when compared to their LinkedIn profile.” – Sejal, S. G2 review
Pros and cons
| Pros | Cons |
| ✅ Advanced search filters that allow for highly targeted lead selection | ❌ Some contacts’ phone numbers are not accurate |
| ✅ Add leads to outreach sequences from the search | ❌ Slight learning curve if you’re only using it for email finding |
Pricing
| Plan | Features | Pricing |
| Free | 100 credits/mo, one credit = 1 email | $0 |
| Basic | 5,000 credits/mo, CRM integrations | $59 |
| Professional | 10,000 credits/mo, plus CRM integrations | $99 |
| Organization | 15,000 credits/mo, CRM integrations | $149 |
Final take: Is Apollo good for finding accurate email addresses?
Apollo is fast, feature-rich, and well-suited for teams that want email discovery built into their sales engagement workflow. Accuracy can be inconsistent because it pulls data from a massive static database.
4. Hunter.io – best for accurate, domain-based email discovery
- ⭐️ G2: 4.4/5
- ⭐️ Capterra: 4.6/5
Hunter is built around one of the most extensive databases of professional email addresses—over 100 million and counting. It’s best known for helping users find accurate, domain-based emails tied to a company website.
You can search by company domain or by full name + company, and the Email Finder will return matching results along with a confidence score. Every email goes through a verification check, and Hunter flags the status to help you decide whether it’s safe to use.
Setup experience
Hunter is simple to set up and doesn’t require CSV uploads or third-party connections. Just enter a domain name or full name + company, and the tool will return matching emails and their verification status.
You can also upload a list in bulk or use the Chrome extension to discover emails while browsing LinkedIn or company websites. CRM integrations (like HubSpot or Salesforce) are available on paid plans for exporting leads directly into your workflows.
In testing, Hunter’s Domain Search feature returned high-confidence results in our tests, and saving contacts to lists or adding them to campaigns was fast and frictionless.
Standout features that help with email finding
- Domain-based email search via company name or full name + company
- Chrome extension for finding and saving emails on LinkedIn and company sites
- Built-in email verification with confidence scoring to reduce bounce rates
- Discovery source tracking with public link references and timestamps
Note: While Hunter’s Chrome extension is great for sourcing emails from websites, it won’t work directly on LinkedIn.
What users are saying
“Its clean user interface makes finding email addresses for LinkedIn connections easy.” – Verified user. G2 review
“The dislike thing is it primarily focuses on extracting leads using the website, and not all websites can provide adequate professional email addresses.” – Sushil, K., Capterra review
Pros and cons
| Pros | Cons |
| ✅ Provides a complete set of features for successful outreach campaigns | ❌ Entry plan starts at $49; costs can add up for small teams |
| ✅ Reliable email verification | ❌ Limited email searches on free plan |
Pricing
| Plan | Features | Price |
| Free | 25 email search credits | $0/mo |
| Starter | 500 + $5.00 per 100 email credits | $49/mo |
| Growth | 5,000 + $3.00 per 100 email credits | $149/mo |
| Scale | 10,000 email searches + $2.00 per 100 email credits | $299/mo |
Final take: Is Hunter good for finding accurate email addresses?
Hunter is a reliable option for finding email addresses when targeting contacts by domain. Its strength lies in accuracy and verification rather than bulk data collection. It may be less suited for users who need multi-step enrichment or automated workflows.
5. Kaspr: best for real-time contact discovery on LinkedIn
- ⭐️ G2: 4.4/5
- ⭐️ Capterra: 4.5/5
Kaspr is a LinkedIn-focused Chrome extension that allows users to reveal verified emails and phone numbers in real time while viewing LinkedIn profiles. It taps into Kaspr’s contact database to surface accurate information.
Setup experience
After installing the Chrome extension and connecting your LinkedIn account, you can view verified emails, their verification status, and phone numbers directly on LinkedIn profiles.
During testing, Kaspr felt like a lighter, more focused alternative to tools like GetProspect and Apollo. The interface is clean, and we liked how easy it was to save leads into lists.
Standout features that help with finding emails
- Chrome extension for accessing contact details on any LinkedIn profile
- Extensive B2B contact database with 500M+ email addresses and phone numbers (vendor-reported)
- Strong EU/UK coverage; sources claim GDPR-compliant processes
- Integrates with CRMs like HubSpot, Salesforce, Zoho, Brevo
What users are saying
“Kaspr is very simple to add to Chrome as an extension. When I visit LinkedIn pages, it displays a summary of the person or company, including their email address and phone number.” – Glen, S. Capterra review
Prospect responsibly—heavy automation can trigger platform limits on LinkedIn.
Pros and cons
| Pros | Cons |
| ✅ Chrome extension is lightweight, fast, and built for speed | ❌ Very limited free credits |
| ✅ No need to upload CSVs or switch tools during prospecting | ❌ Accuracy depends entirely on Kaspr’s internal database |
Pricing

| Free | 15 email credits | €0/mo |
| Starter | Unlimited B2B email credits | €59/mo |
| Business | Unlimited B2B email credits | €99/mo |
| Enterprise | Custom features | Custom pricing |
Final take: Is Kaspr good for finding accurate email addresses?
Yes, for prospecting directly inside LinkedIn. Kaspr’s real-time Chrome extension is designed for reps who prospect on a profile-by-profile basis and want contact info instantly. Its database powers the results behind the extension, so you don’t need to upload lists or use a dashboard.
