I’ve Tested the Best Email Lookup Tools and Here’s What Works in 2026

Building bridges with leads is tough when all the information you have is their name or company website. Luckily, there are ready–made solutions that help you look up leads’ emails using available data. And yet, not many of them can boast of finding valid business contacts. 

In this article, we’ll provide you with the most accurate email lookup tools, discover their features, pros, cons, and pricing, so you can choose the right solution for your business. As a bonus, we’ll also explore what email reverse tools are and when you might need them.

TL;DR: Top 5 email lookup tools (based on my research) 

I’ve reviewed email finder software in detail and identified five solutions that, based on my research, strike the best balance between features, customer reviews, and affordable pricing. Feel free to click on the software you’re interested in for direct navigation:

Below, we’ll discuss these and other tools in detail, but let’s make sure you understand the basics about how email lookup tools work and why we need them in 2026.

What are email search tools, and how do they work?

An email lookup tool, or an email finder, is an instrument that allows getting a lead’s email address based on their personal data. This may include their name, the company’s name, links on social media, and so on. 

The accuracy of results can vary across platforms, so it’s important to choose a reliable tool. For example, Snov.io reports over 98% email deliverability.

But what exactly happens behind the scenes with these platforms? They usually rely on several core technologies:

• Pattern matching: Predicts likely email formats using common naming conventions and domain structures.
• Data verification: Checks whether an email address is correctly formatted, active, and able to receive messages.
• Web scraping: Crawls websites and parses HTML to extract emails from visible content and hidden data. 

These tools also come in various forms, such as:

• Browser extensions
• Web applications
• API-based solutions

Browser extensions allow real-time email discovery while browsing. Web applications offer advanced search and bulk processing features through a central platform. As for API-based solutions, they are designed for developers to integrate email lookup capabilities into their own software or systems.

Why use email lookup tools 

Email finder software comes with lots of advantages beyond just locating contact data. Here is how you and your business can benefit: 

• Save time: Email address lookup software automates the discovery process, letting you focus on strategic tasks and growing your overall productivity.
• Boost accuracy: Professional email lookup tools can also verify business addresses on the go, helping you reduce bounce rates.
• Enhance campaign success: Qualified contacts on your list ensure your messages reach real inboxes, increasing engagement.
• Save costs: These tools are usually more affordable than purchasing pre-built lists, but unlike the latter, they bring you more qualified contacts and leads.
• Integrate your sales workflow: Lead generation tools seamlessly fit into your CRM and tools, allowing you to keep your marketing and sales tasks in one place.

With a good B2B email lookup software, you can get qualified leads in less time, maintain decent email deliverability, and boost your prospecting and outreach efforts significantly.

How I selected and evaluated email finder tools for my test

I selected these tools based on:

• Popularity and reputation: All tools are widely used in B2B prospecting and have solid reputations in the industry.
• Positive G2 ratings: I gave preference to tools with strong G2 reviews, which often reflect real user satisfaction.
• Free trials or plans: Each tool offers a free trial or freemium plan, making it accessible for individual users or small teams to try all features before committing.
• Useful feature sets: Many of the tools included advanced filtering, verification, as well as basic outreach automation, which are essential for effective prospecting.

To provide a realistic, hands-on comparison of the best email lookup tools, I tested several solutions using the same structured process. The goal was to evaluate how well each platform performs under real-world conditions. 

To make the testing fair and measurable, I used a sample of 50 individual contacts, each with a publicly known first name, last name, and company domain. I selected the contacts from established companies of various sizes and industries.

Each tool was rated across seven key criteria:

• Accuracy of results

This is arguably the most important factor. I looked at the percentage of deliverable emails each tool returned, paying attention to whether they actually matched the person searched. Accuracy directly affects bounce rates and outreach effectiveness.

• Data enrichment 

Beyond just locating contacts, I’ve found it valuable to see what additional information each platform could provide, such as job titles, social profiles, company size, or industry. This kind of enrichment is critical for personalization and segmentation.

• Verification features

Having a built-in verifier helps save time, ensuring you’re not loading your outreach tools with bad data. I evaluated how well each service handled internal validation and labeling of results (such as valid, catch-all, or risky).

• Ease of use

I considered how intuitive each platform felt, how smooth the onboarding process was, and whether the tools could be used by someone without technical knowledge.

• Integrations and outreach automation features

I’ve considered whether each tool offers integrations with platforms like HubSpot, Salesforce, Pipedrive, Zoho, Marketo, Mailchimp, and provides outreach automation features. These help push leads into your CRM, automate follow-ups, and keep workflows smooth.

• Value for money

I also evaluated each email lookup software based on pricing transparency, the availability of free credits, and how well the price aligns with the features.

• Compliance

Businesses should be protected from legal issues connected with the violation of personal data processing. I checked whether all email finder tools comply with data protection laws such as GDPR and CAN-SPAM, and provide features like consent tracking and unsubscribe links. This ensures their users’ personal information is gathered, stored, and used properly.

After collecting the results, I verified all found email addresses using a third-party verifier called Verifalia to ensure accuracy and deliverability. 

This framework allowed me to consistently evaluate each tool and provide clear, side-by-side insights on its strengths and limitations. 

Let’s get into my email lookup comparison!

My experience with Apollo.io:

My honest opinion about Apollo.io:

This email lookup tool is good for data enrichment, letting you access additional information about prospects like phone numbers and social links for outreach.

I liked Prospeo’s easy and intuitive workspace, really. Yet, to my mind, the tool is better suited for simple prospecting workflows, as it lacks enrichment and email sequencing features.

My experience with Voila Norbert:

My honest opinion about Voila Norbert:

This service is generally easy to use but can feel a bit outdated and slower to navigate compared to other tools. Plus, frankly, the fact that free leads don’t get renewed monthly, and you need to pay additional fees for using sequences, feels a bit uncomfortable.

How to find someone’s email address using different methods (Snov.io case study) 

Apart from choosing your email lookup tool, you may also be interested in how to find emails with its help. Well, there are many email finder methods depending on the goals you pursue. In this chapter, I’ll show the most popular ones using Snov.io as an example.

How to find someone’s email address if I only know the prospect’s full name and the company name 

Email lookup services like Snov.io can offer you many options. If you need to find an email address of one particular person, Single Email Search is at your disposal. All you need to do is fill in a person’s full name and a company domain name, and Snov.io will do the rest:

And that’s all!

How to find someone’s email address if I know a company website

You may want to get a list of prospects who work for the company you are interested in. In this case, use the email domain lookup option. What you need is just a company’s domain name.

The tool will provide you with a list of people whom you may filter by position. Their emails will be displayed right after you add them to your list. Easy, right?

If you want to get employees’ emails from various companies, you may do it easily with Bulk Domain Search. You just need to upload a CSV file with domain names from your computer or choose one of the lists of companies you’ve previously found and saved to your account.

The service will find emails associated with these domains in seconds.

How to find someone’s email address and company data

If you know which companies you need to find info on, you can take advantage of Snov.io’s database search feature. To do this, create a free account on Snov.io and choose the Database Search tool. 

It will help you find a complete company profile, including the names and professional emails of employees. You can search for businesses by:

• Company name
• Company location
• Industry
• Company size
• Founding date
• Revenue
• Specialities

You can choose any of these filters or combine them as you like.

You can also find email addresses of companies using filters such as company location, industry, size, etc.

You can go to the company’s profile page, where you’ll see all the publicly available information about it.

How to find someone’s email address right in my browser

Such a solution exists, and it will be your real finding. Snov.io offers the Email Finder Extension, which allows you to collect prospects’ emails from any corporate website.

As soon as you install the extension, you’ll see Snov.io’s icon in the top right–hand corner of your browser.

LinkedIn Email Finder works with Sales Navigator perfectly well, too:

As you can see, there are numerous ways you can look up emails. With Snov.io, all of them are available for free, so that startups or small teams can quickly evaluate their growth potential.

Reverse email search tools and methods

But what to do if you know an email address but need other data about your potential customers? That’s where reverse email lookup tools come in. 

A reverse email lookup tool is a software that helps in searching for a person’s detailed data using only their email address. 

These services are great for verifying unknown contacts, enriching your leads, or identifying potential prospects from limited data. They give access to essential details like name, company, job title, as well as social media profiles. 

How reverse email search tools work

The operating principle is simple: you type in the email address you are interested in, wait for the tool to perform the search, and collect the results. It provides you with all kinds of public information found on the web: 

• First name
• Last name
• Country/Location
• Phone numbers
• Social media profiles
• Photos, etc.

If the email is fake or invalid, you won’t get any data. That’s why you need to verify business emails before performing a reverse search.

Reverse email lookup: typical use cases and tool examples

Whether you are a sales rep or a marketing professional, you might have ever experienced one of the following scenarios:

Use case #1: I have an email list, but no personal data

Reverse search tools can access public databases to identify contacts associated with specific emails. If the person has shared their info on social media or has a profile on e-commerce services, you will likely find the data you need.

Services that may help: Cocofinder, Social Catfish, Spokeo, and EmailSherlock.

Use case #2: I need personal data on the go 

If you’ve already started composing an email and realized you have no information on the recipient at all, some email clients can help you out by working as reverse search tools.

For instance, to find a name in Outlook, click the email owner’s Outlook profile, and you will see their details, including name and social profile links. If they don’t have any social links in their Outlook profile, you can at least see their name.

Other services that may help:  Polymail (for Mac users); MailBird (for Windows users).

Use case #3: I need a tool right in my browser

Even among Chrome extensions, you can find a reverse email lookup tool. It shows the information about the sender, like their name, social profiles, and other public info, when you click on an email. 

Services that may help: LinkedIn Sales Navigator, FullContact (for Gmail users).

🖊️ The key problem with reverse email address lookup Although reverse tools are great and user–friendly, they are usually bare–bones services with limited options. Additionally, some providers don’t offer free plans, which may not be cost-effective, especially if you only need to check a few email addresses.

How to choose the right email lookup tool

As you’ve noticed, there are dozens of email lookup services that will tempt you to try their product. Still, before making your choice, think about the following factors:

Your goals

Depending on the size of your company, objections may differ considerably. Define what you want to achieve first. 

• Why this matters: Your goals determine the features you actually need, such as bulk search or CRM integration.
• Questions to ask yourself: What’s my monthly search volume? Do I care more about speed or accuracy?

✅ Good match: A tool with bulk search and export options for large outreach.
❌ Bad match: A limited plan if you send hundreds of messages each week.

Type of email lookup service

As soon as you understand your direction, think about what kind of search tools you might need. Will an email search be enough, or do you also need a company’s profile? Maybe you require an extension right in your browser? 

• Why this matters: Some tools only find emails, others offer additional data like company info, job titles, or browser extensions.
• Questions to ask yourself: Do I need full profiles or just email addresses? Will I benefit from using this tool inside my browser?

✅ Good match: A tool that combines contact lookup with data enrichment.
❌ Bad match: A tool that only finds addresses when you need broader data.

Email verification

It’s not enough just to find contact details — you need to know if it’s valid. Otherwise, you risk high bounce rates and damaged sender reputation.

• Why this matters: Deliverability is crucial for cold outreach. A tool that instantly verifies contacts saves time and protects your domain.
• Questions to ask yourself: Does this tool verify contacts in real time? Can I bulk-verify a large list?

✅ Good match: A tool that automatically validates emails before export.
❌ Bad match: A lookup service that only finds addresses without checking if they actually work.

After testing 90% of similar tools, I’ve concluded that Snov.io’s email verifier is the best on the market. You can be sure that if it’s verified (green), then it will hit the inbox.

Advanced features and integrations

Some tools stop at search, while others take it a step further with advanced workflows. For example, having a built-in CRM (like Snov.io does) is a big advantage as you can manage leads in one place without switching tools. But even if there’s no native CRM, it’s important that the tool integrates smoothly with your existing stack.

• Why this matters: Strong integrations and advanced features save time, prevent data loss, and streamline your outreach process.
• Questions to ask yourself: Does the tool have a built-in CRM? Can I integrate it with my current CRM or marketing automation platform?

✅ Good match: A tool with its own CRM or easy integrations with HubSpot, Salesforce, etc.
❌ Bad match: A closed system that doesn’t let you export or sync your data.

Price and freemiums

If you are a company taking its first steps in the market, you’ll most likely want to have a free trial to see how the service works and determine whether it meets your needs. Even if you’ve chosen your plan, compare it with the options other services offer.

• Why this matters: Early-stage companies need flexibility. Trials let you test features before paying.
• Questions to ask yourself: Is there a free trial or low-cost starter plan? Are there any usage limits?

✅ Good match: A tool with a free trial and transparent pricing.
❌ Bad match: An expensive plan with limited features, no trial, unclear pricing.

Positive reviews

Still have any doubts about what email address lookup service will bring you all the success in the world? Why not look at what other companies think about the search tools they’ve already tried or are using at the moment? For example, you may visit such platforms as G2 or Capterra, where you’ll find lots of user experience feedback. 

• Why this matters: Reviews can highlight consistent issues or confirm the tool’s strengths.
• Questions to ask yourself: What are users saying about accuracy and reliability? Any red flags?

✅Good match: A well-reviewed tool with strong feedback on data quality.
❌Bad match: A tool with repeated complaints about inaccuracies or support.

Best practices to get the most out of email address lookup

This is how I recommend approaching your email finding process to get the best results:

Start with a clear goal 

Having a clear goal in mind helps you stay on track, leading to better results. Whether you’re reaching out for business or collaboration, looking to generate leads, recruit new talent, or expand your network, clarity in your goal keeps your actions aligned.

Leverage advanced search filters

This allows you to efficiently target the right contacts by refining your search based on specific criteria. Such tools as Snov.io offer options to filter by job title, skills, and location, as well as company information like industry and company size. You can include or exclude specific keywords to tailor results to your needs.

Try Google Search Operators

Search engines like Google offer another way to locate publicly available email addresses. The key is using search operators to make your queries more precise.

For basic lookups, you can try combining a person’s name with simple keywords, such as:

• [Full Name] + email

• [Full Name] + contact

• [Full Name] + company name

If that doesn’t yield results, advanced operators can make your search more precise. For example:

• site:company.com + [Full Name] + email – limits results to a specific domain
• intitle:contact site:company.com – finds pages with “contact” in the title on a given site
• “Full Name” email filetype:pdf – searches documents that may include contact details

These operators help locate contact details in team pages, author bios, reports, or published documents.

Explore social media 

Many professionals share their contact details on LinkedIn, Twitter (X), etc. Checking LinkedIn profiles is often a good starting point, as the Contact Info section frequently includes what you are looking for.

Alternatively, you can install LinkedIn Email Finder to quickly and easily collect contact information, as we’ve mentioned earlier.

Both of these methods are very straightforward and manageable without unnecessary effort.

Use WHOIS

When standard methods don’t yield results, a WHOIS lookup can help. WHOIS is a public record of domain registration that often includes the owner’s or administrator’s contact information, including email addresses.

Verify email addresses 

Verification should always be an integral part of your lookup process. Even the most sophisticated search techniques are worthless if the addresses you find are outdated or incorrect.

Quality verification tools help ensure your outreach efforts reach real people.

How to measure ROI from your email lookup efforts

Finding contact details is only the first step. To truly benefit from email address lookup tools, you need to measure results by tracking the right metrics and comparing them to your business goals to understand ROI.

Track key metrics

Keep tabs on these essential metrics: 

Lead conversion rate: Track what percentage of found emails convert into qualified leads.

Reply rates: Track responses from your outreach. Low reply rates under 2-3% often indicate some contacts on your list are not really interested in what you offer. 

Bounce rates: Monitor emails that fail to reach recipients’ inboxes. Bounce rates above 10% suggest poor list quality, which may harm your sender reputation.

Ask the right questions

Don’t shy away from questions like: 

• Are the emails I’m finding turning into conversations, leads, or customers? 

• Am I reaching the right people? 

• Is the time and money I’m spending on lookup tools justified by the results?

Answering these questions can reveal whether your efforts are truly effective or there’s something you should optimize. 

Calculate ROI

Use the standard ROI formula: ROI = (Revenue – Cost) / Cost × 100

For meaningful results, account for all expenses tied to your email lookup efforts. This includes tool subscriptions, staff time, as well as other resources invested in the process.

Optimize continuously

If ROI is lower than expected, review your lookup sources, verification process, and targeting strategy. Continuous adjustments ensure that every lookup contributes to business growth.

By regularly measuring ROI, you will know whether your lookup strategy is delivering real business impact or needs improvement. This ensures that your investment always supports your long-term goals.
