Free Email Finder Tools Test And Review: Clearbit Connect vs Hunter vs FindThatLead vs
Free email finder tools review

When was the last time you had to send a bunch of cold emails as a part of some marketing campaign? Did you have trouble finding the right contact information?

If you didn’t, well, you are one lucky guy – and you are probably not reading this post right now 🙂

Most of us are not that fortunate so we know the struggle of finding reliable contact information. After all, you didn’t just spend an hour writing a perfect pitch, just to be forced to send it to a “support” account because you couldn’t find the editor’s email.

But whenever there is a problem – there is a 99% chance that there is some app out there that is trying to help you solve it – enter free email finder tools.

Why free? We found that there are some free tools that do this job pretty well so we decided to focus only on them.

If you are interested in knowing how these email finding tools work and how well did they perform in our test, stick around and your curiosity shall be rewarded.

How did we choose the tools for this test?

Now that we are in the same boat, there is one small confession we have to make: these tools are not completely free. If you are doing a mass outreach and need to crank out 500 emails in one month, you will hit some limitations.

For everyone else that is doing a reasonable outreach, these tools should be more than enough.

These were the requirements:

  • a renewable plan with a minimum of 50 free contacts you could search for each month
  • the ability to search by domain

We did internally try out a few additional tools that met these requirements but their performance was subpar so there was no point including them in this test and review.

You might think these are not high-level requirements but it helped as filter out more than 20 different tools we initially considered for this review.

Clearbit Connect review

Clearbit Connect is a Chrome extension which provides you contacts inside Gmail and Outlook accounts. It’s one small feature of a bigger tool called Clearbit – a marketing data engine for all customer interactions.

The number of free monthly search credits: 100 credits per month

Available: Gmail Extension, Outlook Extension

How does it work?

Do you have Gmail or Outlook account? If the answer is yes, PERFECT! You can start using Clearbit Connect immediately (well, you need to take a minute or two to install the plug-in).

You don’t have to have a business email address to use it as Clearbit Connect works with any email account. When you’re done with the installation, you can start searching for the contacts. Just log in to your Gmail account and click on its icon which can be found in the right sidebar.

Clearbit Connect Gmail Extension

If you are using Outlook, the process is a bit different. Find the tool by clicking on the marked area shown in the picture below.

Clearbit Connect Outlook Extension

The process of finding emails slightly varies between Gmail and Outlook. The first step, to find contacts in Gmail, is to copy the domain in the search area. You will need to copy only the second-level domain name, without HTTP, HTTPS, or even www. That means if you copy the whole domain in the search area you probably won’t get any contacts at all.

For example, if you are searching for our contact information, you should copy only the “” part, andavoid pasting the “https://www” because Clearbit Connect doesn’t always recognize the domain if you use full URL.

You don’t have to worry about it in Outlook as it recognizes the domain regardless of the format you use.

After opening the results by clicking on the icon of the domain, you get a list of found contacts for that domain that are presumably working for the company.

One awesome thing that Clearbit Connect has, which for some reasons works only with Gmail, is Role and Seniority. With this, you can search and filter the results by their title/job.

Clearbit Connect Filter

By clicking on a person, you will get their name, photo, title, URL, and social accounts. You’ll get the same info whether you’re searching through Outlook or Gmail.

As we already mentioned, this email finding tool is going to give you 100 credits per month for free. If 100 credits per month are not enough for your needs, you can pay for a premium service which will cost you $6k a year for 1000 credits per month.

Every found contact will cost you one credit which is spent by clicking on the contact and revealing its email address.

The credits won’t be spent by simply searching for the domain. It will be spent only when you click on the person you want to reach out to; when Clearbit Connect shows you this person’s contact information. If you, for example, click and reveal 3 contacts from the same domain, that will use 3 of your credits.

Last but not least, it’s useful to know that you will get a permanent bonus of 10 monthly credits for each person that started using Clearbit Connect through your invite.

Hunter review

Hunter is an email finder tool that can help you find relevant contact information for your outreach campaigns. A few different ways of searching email addresses aside, Hunter also offers an additional feature called Mailtracker – a simple and free email tracker for Gmail.

Hunter Review

The number of free monthly search credits: 100 search credits per month

Available: Web app, Chrome Extension, Google Sheets

How does it work?

Hunter features that will ease your process of finding email addresses are as follows:

  • Domain search – find email addresses associated with the chosen domain.
  • Email finder – find the email addresses with the combination of “full name + domain”.
  • Email verifier – verify the deliverability of the wanted email address.
  • Bulk tasks – search or verify lists of emails addresses.

If you want to use Hunter for searching your contacts, you’ll have to create an account. There are two options – using your company email or signing up with your Google account.

Using Chrome extension

In case you want to speed up the process of searching contacts, we recommend you to add Chrome extension.

Hunter Chrome Extension

On the photo above, you can see all of the contacts Hunter has found for our domain. A little green dot with a ‘check’ sign next to the email means that Hunter was able to verify the email address.

Additionally, the little ‘plus’ sign offers you the possibility to save the contact to your Lead list – the place where you can save your contacts in case you’ll need them in the future. This list can be found inside the Hunter web app.

This is helpful when you work on different projects because you can create a list of contacts for each of them and save some time by sending emails directly from the web app. Before that, however, you will need to connect it with your Gmail account. (see the photo below)

Hunter App And Gmail

Using the Web app for Domain Search

The process is really simple – go to Domain search feature, paste the URL of the wanted domain, and your results will appear in a second. Here’s how it looks:

Hunter Domain Search

Sometimes, especially when you have a bigger list, contacts are grouped by departments – marketing (see the photo above), management, communication, executive, sales, etc. Except for the name and the email address Hunter will, occasionally, show you the job position/role of the contacts and link to their social networks like LinkedIn or Twitter.

In most cases,  you’ll see 2 type of icons beside the email addresses themselves:

  • a green icon with a ‘check’ sign inside it  – it means this is a verified email
  • green or yellow dot – represents confidence score (how certain Hunter is that the email works)

If you look carefully at the photo above, there is also a little grey ‘check’ sign beside every contact with a green or yellow dot. If you click on it, the email address it accompanies will be verified and you’ll lose 1 additional credit. After verification is done, you’ll get the deliverability results.

Emails with a high confidence score (above 90%) have a higher chance of being fully deliverable but that’s not always a case and the photo above is a great example. It’s important to note that the Hunter is updating the confidence score on a regular basis.

How are the credits spent?

We have already mentioned that Hunter offers 100 monthly credits for free which is more than enough for regular outreach projects. If that isn’t enough for you, the pricing plan scales from 34€ per month for 1,000 credits to 279€ per month for 50,000 credits.

The formula for spending credits is very simple.It doesn’t matter if you are…

  • searching by domain
  • trying to find a contact through a combination of “full name + domain
  • verifying emails

…you’ll lose one credit for each of the mentioned actions. If you search the same site more than once, you won’t lose any additional credits.

You’ll get charged with one additional credit in case you’re loading more contacts (‘Show more’ button at the end of the page) and when you click to filter the results by wanted department (e.g. marketing, management…). review is a platform used by marketers, startups, recruiters and others working with email outreach or outbound research. It offers a lot of different options, from simple domain search to creating and managing a whole outreach campaign. In this article, we’ll focus on a few selected features that can help you find the right email addresses. Review

The number of free monthly search credits: 100 search credits per month

Available: Web App, Chrome Extension

How does it work? has a few different features you can use for finding email addresses:

  • Domain search – find all email addresses associated with the selected domain.
  • Bulk domain search – find emails from a list of different domains.
  • Company profile search  – find companies by name, location, industry, size and more.
  • Social URL search – find emails by browsing social network profiles (LinkedIn, Twitter and Facebook).
  • Emails from names – find an email of your contact when you know their name and company.

The first thing you’ll have to do if you want to try one of these is to create your account – nothing special, choose your email and password and you’re ready to go. Alternatively, you can just sign in with your Google account.

Using Chrome extension

Our advice is to add their Chrome extension as that speeds things up. You won’t have to go to web app and instead, you’ll just click on icon on your taskbar and the results will appear in a second. Chrome Extension

As you can see on the photo above, some emails are faded out which means that they are already inside your People List – a place where you can save your contacts in case you think you’ll need to use them again at some point in the future. 

Here is how a list looks. Lists

As you can see on the picture above, some of the emails have a green dot which means that they are valid, while emails with a grey dot are not yet verified.

Using the Web app for Domain Search

In case you don’t want to use Chrome extension, you can always go to the web app, choose Domain search feature and paste the URL of the domain you want to find email contacts for. Domain Search

If you click on the name of the company above that list (which you can see on the photo above), you will get a new window with detailed information about every prospect, but the email addresses will be blurred (see photo below). Detailed Domain Search

Once you save the prospect to your list, you’ll get detailed information but you’ll also be charged with one additional credit.

Find contact info through social networks

The last feature we want to show you (but not the last that offers) is in relation to social networks.

Let’s say that you have a project where you want to get in touch with editors from the US. can help you streamline this process. Here’s how.

Instead of searching for and inspecting relevant websites, go to your LinkedIn profile, type “editor” in a search engine, and add a location. After that, the LinkedIn will give you the list of editors and all you have to do to get their emails is click on the icon in your taskbar after which you can easily save found contacts to one of your lists.

One thing to have in mind is that 1 credit will be taken for each contact you select to save. LinkedIn search

How are the credits spent?

As we’ve mentioned, offers 100 monthly credits for free.

In case you are in charge of big outreach projects and have to go over this limit, you can purchase a plan that is the best fit for you. The pricing plan scales from $29 per month for 1,000 credits to $139 per month for 50,000 credits.

As you can imagine, every feature that helps you find contact information spends some of your credits in one way or another. If we focus on Domain Search feature, there are three choices:

  1. Simple domain search – in this case, you’ll lose 1 credit per search (no matter how many emails you’ll get, except if it doesn’t find any email – then you won’t lose any credits)
  2. Personal Contacts – if you add contacts from ‘Domain Search List’ to your ‘Personal Contact List’, you’ll lose 1 additional credit per prospect because that lets you see additional information like job position/role.
  3. Email verification –  for every unverified email that you decide to verify you’ll lose 0,5 credit. One thing to note, won’t deduct credits for emails that have an uncertain status.

All features that offers are unlocked for every plan (paid and freemium) and you have free hands to decide the way you want to spend your credits.

One thing we learned the hard way is that doesn’t like when you have multiple free accounts on the same domain. We had multiple team members using it and they cancelled all of them at once – this is how we learned about this restriction in the first place.

FindThatLead review

FindThatLead is a tool which is designed to automate the sales process and help you find relevant leads. It is mainly created for B2B but it can be use also for B2C. This tool has a few different features you can use to manage leads but in this review, we will focus only on the ones that help you find contact info for a standard outreach campaign.

The number of free monthly search credits: Free for up to 150 searches/month (100 for using Web app and 50 for using Chrome extension)

Available:Chrome extension, Web app

How does it work?

FindThatLead has a few different features which will help you to find relevant emails:

  • Lead Search – this feature will help you find an email based on the combination of “name + domain”.
  • Domain Search – all you need to do is to input the domain of any company and to find a list of associated emails.
  • Email Verifier – once you have found some emails, you can verify and check if a email address is usable.
  • Social URL Search – search for emails emails through social media profiles (LinkedIn or Twitter).

One small note before we continue, to be able to use this tool, you need to create an account using a business email address.

Find That Lead Log In

Let’s explain how Chrome extension, Web app, and social URL search work as you are going to use them the most.

Finding emails by using Chrome extension

As with other free email finder tools on this list, if you want to make your life easier and workflow faster, you should use their Chrome extension.

When you are on the domain you want to find contacts for, simply click on the icon on your taskbar and it will show you its findings (as you can see on the picture below).

Find That Lead Chrome Extension

The list of found emails will not be verified. You can verify each listed email by clicking on the check mark next to the email.

Find That Lead Email Verify

If you are looking for a specific person, you can type their name in the search area.Sometimes, you will be able to find people which the tool has not listed initially.

For example, the FindThatLead has found 5 contacts for Point Visible. However, our company has more than 5 relevant email addresses. We tried to find Petra (as her email wasn’t on the initial list) – and we were able to find her, as you can see on the picture below.

Find That Lead Search For Specific Person

This shows you that you shouldn’t rely just on the initial search if you know the name of the person you are reaching out to. That goes for all other email finder tools tested too.

Lastly, if you want to save your contacts in a spreadsheet for whatever reason, you can do that by clicking on the ‘’Export CSV’’ icon.

Finding emails by using the Web app

Go to the web app, choose the Domain, and paste the URL of the domain in the search area. By doing that, you will get a list of 10 contacts which you will then need to verify one by one.

Find That Lead Domain Search

Again, you can choose to export these contacts to your Drive or download CSV file.

To load more emails you will need to upgrade up from your free plan. That will cost you $29 and you will get 1500 monthly credits in return.

Finding email using Social URL Search

The last feature we will explain is the social URL search. This feature currently works only with two social networks, LinkedIn and Twitter.

This search works only when you are using a personal social media profile URL. The contact is “locked”, and to get the contact info you will need to click on the button ‘’Get Email’’.

Find That Lead Social URL Search
Find That Lead Social URL Search Verify

Compared to other features, this one seems the least reliable. In our test, from 10 searches, only 2 emails were 99% correct, while the rest were less than 25% correct or the contact couldn’t be found at all.

To be reasonable here, finding email addresses in this way is not something you should have high expectations of in general.

How are the credits spent?

Every feature that you will use to find an email is going to spend some of your credits. Here are a few ways how your credits can be spent:

  • Lead Search – you are going to spend 1 credit for each search and the email comes automatically verified.
  • Email verifier – for each verification you will spend 1 credit.
  • Social URL Search – the tool will try to find the lead profile for free and if the lead profile is found, to generate the email you will spend 1 credit. The email also comes verified as in the Lead Search.
  • Domain Search – this one is a bit complicated. Every 10 results will cost you 1 credit. It means that the tool will display a max of 10 emails for the searched domain in exchange for 1 credit. Note that those listed emails will not be verified which means you will spend 1 additional credit for each verification.

How did we test these free email finder tools?

Since we are running blogger outreach and custom link building campaigns for a few years now, we already had a huge internal list of sites and editor’s contacts.

We wanted to check how many contacts can these free email tools find in general, as well as if they can find the email from the person that has the authority to give you an answer to your pitch, which are in most cases editors and content managers themselves.

We also used this chance to see if there is some variation depending on the “size” of the website you might be checking. So we ran a test on 100 websites where:

  • 20 of them were between 20 and 30 DA
  • 60 of them between 31 and 60 DA
  • 20 with DA 61+

The metrics were taken before the latest Domain Authority update but that wouldn’t have any impact on the final results anyway.

Clearbit Connect vs Hunter vs FindThatLead vs test results

As you will see in the pictures below, we checked 2 different things:

  1. total number of found contacts for every tested domain
  2. looking for a specific person (which exact name and email we already had) that we were in touch with and know for sure they are in charge of content for their respective sites

One thing that is important to mention is to take the total number of contacts found with a truckload of salt. found north of 5k contacts on 2 domains and over 14k on one other domain, which obviously isn’t correct as many of those emails are not usable (e.g. [email protected]).

Additionally, Find That Lead actually found more contacts than it is written in the report below but this tool shows max 10 contacts and you have to spend additional credits to discover more which would burn through your credits really fast. In the same fashion, Clearbit Connect lists max 20 contacts per domain search.

We were considering to remove this from the report but decided to leave it in as we actually spend a decent amount of time testing it.

Here you can see a snapshot of our test setup:

Clearbit vs Hunter  vs FindThatLead vs

And here you can see the final test results:

Free email finder tools test results

As you can see, was a clear winner while the other 3 tools were basically even.

What you should really focus on are the percentages in the “Summed up” row. They show that for the 100 contacts we tested by using the “name + domain” features, was able to find 65 of them, winning this test by a substantial margin.

Our recommendations

Which free email finder tools should you use? Well, seems like an obvious choice to start with. That being said, doesn’t allow multiple free accounts associated with the same domain so if you are an agency or have multiple people doing outreach at the same time, you need to look at other tools on this list too.

Do we have a personal favorite?

Well, every tool has its advantages and disadvantages. In our office, Clearbit Connect has been used the most before this test, mainly because it is really simple to use overall. It doesn’t give you an extraordinary number of contacts, but those that you get are almost always correct.

Similar thing is with Hunter, even though it seems slightly less reliable than Clearbit and you can burn through the credits really fast if you are not careful.

FindThatLead was at a slight disadvantage here as it is not really suited for your standard outreach because the way you spend credits will make you run out of them really fast. As its name suggests, it is a great choice for sales people as it has some great features designed for lead generation.

That being said, nothing is stopping you from using multiple tools. If you install their Chrome extensions, you could probably run a domain through all of these tools in under a minute. Moreover, there are other ways to find contact information you can try out if the tools don’t provide you with the desired results.

Are you using some other free email finder tool that works really well for you and matches our criteria? Let us know in the comments below and we might include it one of our future updates!
