Email Finder: How to Find Professional Emails Easily (5 Best Tools Compared)

You want to contact prospects, but you don’t have their email addresses… so reaching out becomes impossible 😔

📩 Good news: there’s a solution.
Email finder tools help you quickly locate professional email addresses so you can contact your prospects directly.

➡️ In this article, we’ll help you choose the right tool by covering:

• What data enrichment is
• What an email finder is, how it works, and why you should use one
• A comparison of 5 email finder tools: Waalaxy, SalesHandy, Snov.io, lemlist, and Dux-Soup

By the end, we’ll have tested them all—so you’ll know which email finder delivers the best results and how to use it like a pro.

Let’s get started 😎

What Is Data Enrichment?

💎 Data enrichment is the enhancement of existing information by adding additional data from various sources (thanks to data scraping).

The aim is to make this data more complete, accurate and reliable in order to maximize its value for the company. 🎯 This process improves statistical analysis, refining marketing decisions and strategies based on reliable data.

In prospecting, database enrichment enables us to better target prospects and personalize future exchanges, by adding information such as telephone number, email address, location…

This process can be carried out manually or using automated tools (such as Email Finder), which exploit external databases, social networks and APIs. ⚙️

As you can see, we’re going to focus on email enrichment: explanations and comparisons of the best Email Finder tools on the market to follow. 🚨

What Is an Email Finder (and Why Use One)?

An Email Finder is a tool (or a feature within a tool) that lets you quickly find e mail addresses, so you can contact one or more people directly afterwards. 📣 There are two methods of email enrichment:

• Via purchased databases (not to be used).
• Via semantics (method used by Mail Finder tools).

Semantic email enrichment is an algorithm that combines different possible email formats (based on a prospect’s first name, last name or company) and then tests whether these emails are valid. 🧪

Here are the advantages of the ✅ method:

• RGPD compliance and no legal risk.
• Saves time compared with manual or contact searches.
• Reliable, up-to-date results, with systematic verification that the email exists (avoids invalid emails and high bounce rates).
• Use of different sources of information updated by users themselves (for example, LinkedIn, which remains the simplest solution for finding e-mail addresses).
• More efficient prospecting and automation of the contact collection process to quickly obtain contact details, improving the scope and effectiveness of sales initiatives.

👉🏼 In short, email enrichment has become a must-have feature for all prospecting and email automation solutions on the market.

Many of them now offer this Email Finder service and integrate it directly into their platform and campaigns. 📩

🛟 And, to help you choose the best tool for your strategy, we tested four and compared the rates of emails found.

Email Finder Tools Comparison

#1 – Waalaxy: The Best Email Finder for LinkedIn Profiles

Imagine finding professional email addresses from LinkedIn profiles in just 10 minutes a day 🤩

That’s exactly what Waalaxy lets you do and it’s surprisingly easy to use. No technical skills required. 🔍

🤖 Our Mail Finder therefore recovers emails thanks to cascading enrichment: we query different providers (all RGPD-compliant) to provide you with your prospects’ email addresses.

This combination ensures that these are up-to-date, verified professional emails and prevents any nasty surprises. 🔒

In short, here’s how it looks fonctionne👇🏼:

• Automatic verification of the validity of email addresses to reduce risk, ensure that the message reaches its destination and improve email deliverability(mail tester).
• Automatic association of found emails with corresponding contacts in Waalaxy, making it easier to manage and track interactions.
• Easily track and export found e-mails from your prospect lists and campaigns.

Access to Email Finder

Via the Waalaxy extension 👽, the Email Finder can :

• Search for an e-mail address for a single contact.
• Launch a campaign where the only active functionality is the Mail Finder, to search for e-mail addresses on a list of contacts.
• Be included in Waalaxy multi-channel campaigns: LinkedIn & Mailing (always via a list of contacts).

🪙 Waalaxy’s Email Finder functionality works per credits and is accessible either:

• By all subscriptions (from 25 to 500 credits/month depending on the subscription),
• Freemium (25 credits offered free of charge). 🤑
• By purchasing additional credits according to your needs.

Finally, with our Email Finder, you can simplify your collection process as much as possible and start email campaigns with your eyes closed. 😎

👇🏼 Take a look for yourself with our tutorial.

The Email Finder tutorial

Creating an Email Finder campaign couldn’t be easier with Waalaxy!

🖱️ Just click on “Start a campaign” and select « Email Finder », to easily enrich your list of prospects.

You can also choose from over 80 other automated action sequences, which include this functionality. 🤩 For example: Profile visit + Email Finder + LinkedIn Invitation + Message.

After selecting your Waalaxy sequence, you’ll need to name your campaign so you don’t lose it and have access to the full performance results. 📊

Next, you’ll be able to choose from one of three ways to import your leads/contacts:

• 🥇 From LinkedIn.
• 🥈 From an auto-import.
• 🥉 From your lists, for this you must have already run a campaign or at the very least have created a list via a CSV import before launching the campaign.

All you have to do is select the list in question, and let the tool guide you through to the launch of the campaign!

And, just a few minutes later, you’ll get the long-awaited email addresses and the results of your campaign. 🔥

Campaign results

🏆 As far as our campaign is concerned, it was a complete success, with 96 usable business emails found out of the 224 we searched for.

With an excellent found rate of 42.9%. That’s 20.4% more than our competitors (on average) 😈.

If not, stay with us for the rest of the comparison and to discover the scores of other tools. 💥

#2 – SalesHandy: Lead Finder

Saleshandy Lead Finder is a dedicated B2B contact search tool built on a database of 852M+ contacts and 42M+ companies. 🔍

Unlike tools that offer a separate extension alongside a web interface, Saleshandy consolidates everything into one platform, where you can search, filter, verify, and export leads all in the same place, without switching tabs or tools.

Access to Email Finder

As with Waalaxy, Saleshandy Lead Finder can be used as a standalone search or plugged directly into cold email campaigns.

🪙 Saleshandy’s Lead Finder works on a per-credit basis and can be accessed either:

• By subscription (credits scale with plan tier),
• By free trial (a 7-day trial offered free of charge).

✅ A few things that make the process smoother compared to other tools:

• 75+ search filters –  job title, industry, seniority, company size, location, and more, so you can narrow your list before export rather than cleaning it up after.
• Real-time double email verification at the point of export, meaning you’re not working with stale database pulls.
• List import via .csv file is available across subscription tiers.
• Duplicate filtering and invalid address removal are built in — no manual sorting required.

Campaign results

Once your search is complete, Saleshandy displays results by verification status directly in your list:

• ✅ Valid
• ⚠️ Risky
• ❌ Bad
• 🔵 Unverified

💡 To keep this comparison consistent, we’ve only counted Valid results, the same approach we used for the other tools above.

Saleshandy’s real-time double-verification layer delivers a 98% accuracy rate on valid email addresses.

👉🏼 Its real-time verification layer filters out risky and invalid addresses before they ever reach your campaign, keeping your sender reputation clean from the start.

Examining these figures, Saleshandy performs well in both database depth and verification accuracy. 🦾

#3 – Snov.io Email Finder

Snov.io offers two emailfinder tools 🤔 :

• 1️⃣ Tool for online email address search (retrieval of professional email addresses linked to a domain name, which can also be found on LinkedIn and via Waalaxy).

• 2️⃣ Extension for email retrieval via LinkedIn, auto-import (to scrape LinkedIn profiles automatically) or CSV. This is the one we’re concerned with here.

Access to Email Finder

As with Waalaxy, Snov.io can launch “Email Finder” campaigns only, or be included in multi-channel campaigns.

🪙 Snov.io’s Email Finder functionality also works on a per-credit basis and can be accessed either :

• By subscription (from 50 to 5000 credits/month depending on the subscription),
• By free trial (50 credits offered free of charge).

❌ On the other hand, unlike Waalaxy, Snov.io doesn’t offer to buy additional credits as you need them.

So if you’re considering using it, be aware that you won’t be able to add email search credits to your free trial (to pay only for the credits, without the subscription), you’ll need to estimate your need to upgrade to a paid subscription…

⚠️ This isn’t the only thing the tool doesn’t offer and/or that complicates the process:

• Installation of another Chrome extension required for “non-email” enrichment (domains, websites and search results…) and very tedious.
• List import via .csv file is unavailable for freemium subscribers.
• You can’t choose the exact number of emails to scrape (only the number of pages on LinkedIn).
• You can’tuse filters to avoid duplicates or remove invalid e-mails, as they don’t exist, so you’ll have to sort your lists manually.
• No graphs are available for analyzing results and monitoring performance.
• Overall, the tool is far less design-led and intuitive, and very little support is offered for launching the first campaign.

Campaign results

Once you’ve launched and completed your campaign, you’ll find the search results color-coded (according to e-mail status) directly in the relevant list:

• 🌑 Grey: Not found.
• 🟢 Green: Valid.
• 🟡 Yellow: Possibly valid.
• 🔴 Red: Invalid.

As far as our campaign is concerned, the results are rather disappointing 😞 159 emails were found, i.e. only 53 usable and deliverable professional emails, out of the 224 emails searched for.

👉🏼 A very low success rate of 23.6% (less than a third of the desired emails).

Looking at these figures, it’s clear that not only is Waalaxy’s Email Finder easier to use, but it also offers significantly higher scores than Snov.io. 🦾

⏰ Now it’s time to compare it with a second tool: Lemlist.

#4 – The Email Finder from lemlist

Like Snov.io, Lemlist offers two Mail Finder tools:

• 1️⃣ A free online tool that lets you search for a single profile.

• 2️⃣ Extension for email retrieval via LinkedIn, people search or CSV. Once again, this is the method we’re interested in.

Access to the Email Finder

🪙 Lemlist’s Email Finder also works on a per-credit basis and can be accessed either :

• By subscription (from 100 to 1000 credits/month depending on the subscription),
• By free trial (500 credits offered free of charge).
• By purchasing additional credits (up to 10,000).

Unlike Snov.io, we have to admit that Lemlist has put a lot of effort into the design of their app. 🎨

❌ But there are still things the tool doesn’t offer that can complicate the process and getting to grips with it:

• Results take a long time to arrive, compared to Waalaxy’s speed.
• The extension is very slow, making it difficult to navigate (but not really).
• The cost for 1 search = 5 credits is not cheap (on Waalaxy 1 search = 1 credit) and may explain the quantity of credits offered by subscription or purchase.
• No dashboard is available for analyzing results and steering performance.
• Support resources for the extension are only available in English.
• Problems with customer support have been reported by some users.

Campaign results

Once you’ve launched your campaign, you’ll be able to see the results arriving in real time in your contact list. 👀

As on Snov.io, search results oremail enrichment statistics will be sorted by color code (depending on the status of the emails), heading the Enrichment column, in the relevant list:

• 🌑 Gray: Not found or not verified.
• 🔴 Red: Inexploitable.
• 🟡 Yellow: Risky (chances of landing in the recipient’s mailbox spam).
• 🟢 Green: Deliverable.

Regarding our campaign, the results are as follows 😢: 77 emails were found, of which only 55 were professional deliverables, out of the 224 emails searched.

👉🏼 That’s a very small success rate of 24% (less than a third of the desired emails). In a nutshell:

• Compared to Waalaxy, it’s -19% of deliverable emails found.
• Lemlist does just better than Snov.io in terms of professional email deliverables found, but still falls short of the results brought by Waalaxy. 😈

Now it’s time to compare the Waalaxy Email Finder with one last tool: Dux-Soup. 👇🏼

#5 – Dux-soup Email Finder

Dux-Soup offers just one Mail Finder tool per Chrome extension, just like Waalaxy! And, believe me, that’s a plus over the two separate tools offered by Lemlist and Snov.io.

Access to the Email Finder

To launch the Dux-soup 🦢 Email Finder, you’ll need to :

• First create your campaign.
• Then import your prospects (from LinkedIn or .csv file).

🪙 Like the other tools presented, the functionality works by credits (in this case Dux-Soup point).

❌ However, unlike the others, the Email Finder is an option to be taken in addition to the subscription (from 100 to 2000 credits) and is therefore obviously not available as a free trial.

So you won’t be able to test it… 😱

⚠️ That’s not the only thing the extension doesn’t offer and/or complicates the data collection process:

• Not being able to test the Email Finder and having to directly take out a subscription and an option to access it can be a real hindrance.
• It’s hard to understand that you first have to create a campaign, then add a list and associate the campaign in question with it.
• The functionality is activated during lead import (checkbox), so if you don’t venture that far, it’s impossible to find.
• Incorrect operation of the extension, which sometimes on LinkedIn does not detect that another Dux-Soup window is open in the web browser and is indeed connected to the account.

Campaign results

⏳ Once you’ve launched your campaign, you’ll need to wait until it’s finished to see how your leads have been added and the results of your campaign.

There’s no color coding here: Dux-Soup thinks “like Waalaxy” in this respect, i.e. in terms of usable and deliverable e-mails. ✅

👉🏼 With regard to our campaign, here are the results: 49 emails found, out of the 224 emails searched for. That’s still a very low success rate of 21.8%.

It’s a downhill slide for Dux-Soup 🫣, with results and performance indicators well below those of other tools, in addition to complicated access to functionality.

That’s it, that’s the end of this comparison of Emails Finder tools. 🎉 Would you like a summary table of everything we’ve just said?
