Kaspr vs Waalaxy: The Champions Redefining B2B Prospecting

Finding the right contact information and automating your prospecting has never been more crucial to success in B2B. But with all the competition out there promising to revolutionize your prospecting, how do you choose?

If you're drowning in a sea of LinkedIn profiles, desperately trying to extract email addresses and phone numbers while managing your prospecting campaigns, you're not alone. Sales teams around the world are turning to Chrome extensions to bridge the gap between LinkedIn prospecting and successful cold outreach.

Today, we're looking at three powerful extensions that are making waves in the B2B space: Kaspr, Waalaxy, and Emelia. Think of them as your GPS in the jungle of B2B prospecting tools.

Before we dive into the heavyweight battle, let's get the basics straight. B2B Chrome extensions are browser-based tools that optimize your prospecting efforts by integrating directly with platforms such as LinkedIn and Sales Navigator.

These digital Swiss Army knives help you:

• Extract contact information from LinkedIn profiles in the blink of an eye

• Automate prospecting sequences across multiple channels

• Enrich prospect data with verified email addresses and phone numbers

• Streamline your workflow, from prospecting to conversion That's where LinkedIn Chrome extensions come in.

Kaspr is a B2B contact data provider. They source their data from 120 sources, covering over 500 million phone numbers and email addresses.

• Over 120 data sources for maximum coverage

• The Chrome extension can extract phone numbers, email addresses, and company information, either profile by profile or in bulk

• Real-time contact verification

• Works seamlessly with LinkedIn Sales Navigator

• GDPR and CCPA compliant data processing

💸 However, its credit-based system has a drawback: starting at $45 per month for only 100 credits, prices can quickly add up, especially for large-scale prospecting. Add to that limitations such as credit caps, gaps in regional data, and a lack of advanced automation features, and it's easy to see why many Kaspr users are looking for alternatives that offer more value without breaking the bank.

Pros 👍

• With Kaspr, you get access to accurate phone numbers and email addresses with a single click.

• Exceptional data accuracy, especially for European markets.

• Start booking appointments with Kaspr's LinkedIn Chrome extension within minutes of installation.

Cons: 👎

• Higher cost per credit than competitors

• Automation features limited beyond data extraction

• Focuses primarily on contact data rather than comprehensive campaign management

Waalaxy is a B2B prospecting tool on LinkedIn that allows you to manage multiple campaigns across multiple channels. By subscribing to Waalaxy, you will have access to several features such as an email address search tool, a LinkedIn prospecting tool, and an email campaign tool.

• LinkedIn automation for connection requests and messaging

• Chrome extension to extract simple LinkedIn searches or advanced LinkedIn Sales Navigator searches

• Multi-channel sequences combining LinkedIn + email

Waalaxy offers three different pricing tiers: Pro, Advanced, and Business.

Strengths 👍

• Complete automation suite

• Google Chrome extension that allows you to extract advanced search results from LinkedIn Sales Navigator

• Multichannel campaign management

• User-friendly interface

Weaknesses 👎

• Since 2023, Waalaxy has increased its prices 💸 And we think they've pushed the prices a little (a lot) too far

• Waalaxy is a lead generation tool that provides data, but only email addresses. It does not provide phone numbers or direct numbers

When it comes to alternatives to Kaspr, Emelia.io clearly stands out from its competitors. It's not just a contact search tool, but a complete prospecting solution with unlimited real-time LinkedIn data extraction, 99% accurate email enrichment, phone numbers, and powerful automation features.

While competitors like Waalaxy overwhelm users with complex navigation and excessive options, Emelia prioritizes simplicity without sacrificing functionality. Users can set up and launch campaigns in minutes rather than hours, making it accessible even to those with limited technical expertise.

Emelia is redefining B2B prospecting with a platform that combines intelligence, flexibility, and accessibility. Whether you're a solo entrepreneur or a growing team, Emelia gives you the keys to turn every opportunity into success, without breaking your budget.

Here's a topic most people don't talk about: Chrome extension security. Waalaxy works as a Chrome extension, which poses security risks because it modifies the code of the LinkedIn web page. This method is very easy to detect and can result in restrictions or bans on account access.

Security best practices:

• Choose extensions with transparent privacy policies

• Look for GDPR compliance certifications

• Avoid tools that require excessive permissions

• Monitor your LinkedIn account for unusual activity

• Customer support: Kaspr, Waalaxy, Emelia

Customer service plays a key role in the user experience of prospecting tools such as Kaspr, Waalaxy, and Emelia, with varying approaches and performance depending on needs and regions.

Pros: Support is responsive to simple issues, with quick solutions via chat or email. Cons: Users report recurring bugs (LinkedIn automations, HubSpot integrations) and sometimes non-existent support, with slow or no responses. Reviews vary, ranging from 2 to 4/5 on Trustpilot and Product Hunt.

Pros: European users appreciate the quick responses (6 days/week) and multilingual support via chat. Cons: Users in the US report response times (up to 24 hours) and bugs (campaigns, interface), with support that is sometimes unempathetic. Ratings range from 3 to 4/5 on Trustpilot.

Pros: The team, including the founders, offers responsive support via chat and video, with personalized advice and educational resources. Regular checks optimize the experience. Responses are provided instantly, much to the delight of users. Cons:

Here are four authentic customer reviews for Emelia, taken from available sources:

1. Positive review (emelia.io, date not specified): “As a freelancer, I've already tested many tools to automate prospecting for all my clients and myself, and Emelia is the tool that has given me the best results. And I don't waste time setting up my account, which is great!” “🚀

2. Positive review (emelia.io, date not specified): ”I discovered Emelia in its early days and the customer support is really what makes the difference. Even now, they are still just as responsive and give valuable advice.“👍

3. Positive review (toolsboxseo.com, 2025): ”Emelia is the best compromise between power and simplicity: I tripled my appointments in two months!“ — Clara, Head of Growth😊

4. Positive review (toolsboxseo.com, 2025): ”LinkedIn automation combined with email warm-up has allowed me to go from 10 to 40 qualified leads every week!" — Malik, Founder of AgileMedia👏

• Positive review (Trustpilot, 2020): "The data is relevant, simple, and easily accessible. Customer service is extremely responsive and friendly (a big thank you to Amanda for taking the time to answer my many questions ;) ). Of course, there may be an error in the numbers from time to time, but the gain is real and considerable. I have been recommending Kaspr for two years and will continue to do so.“👍

• Positive review (Trustpilot, 2020): ”It's comprehensive, detailed, and effective. I would recommend Kaspr without hesitation. As an entrepreneur, it has become my go-to tool for developing my B2B business."👏

• Negative review (Trustpilot, Jan 2025): "Not surprised by the bad reviews, which I agree with 100%. I am very disappointed with the service offered. The subscription is strict: if you cancel, you lose all your credits. Your direct competitors, such as Lusha, allow you to keep your credits even after the subscription ends. This is not the case with you, even though we pay specifically for these credits! In addition, your practices seem to border on the limits of the GDPR, which probably explains the recent fine imposed by the CNIL.“👎

• Negative review (Trustpilot, 2022): ”Good account executive and always responsive. However, the extension can be quite buggy and really doesn't perform well in some regions. The biggest issue was paying for over 300 credits without having time to collect the data. We didn't want to continue being billed, so we canceled the subscription. But Kaspr deleted all the credits WE HAD PAID FOR."🤨

• Positive review (Trustpilot, 2024): “I've been using Waalaxy for several months and I'm very satisfied. The interface is intuitive, the campaigns are easy to set up, and I've clearly become more efficient in my LinkedIn prospecting. It's become a real ally in my daily work.”👏

• Positive review (Trustpilot, 2023): “Excellent experience, I've been a subscriber since it launched, this software is impressively efficient. You have a salesperson working for you 24/7, prospecting for you and reactivating your LinkedIn network. I haven't found a tool this comprehensive at this price.”👍

• Negative review (Trustpilot, 2023): “You pay for the license and you have to respond to mandatory surveys that you can't ignore. On top of that, you get Waalaxy banner ads on LinkedIn that are impossible to remove. If that doesn't bother you after paying for the license, go for it. Personally, I don't recommend it.”🤨

• Negative review (Trustpilot, 2024): "The app is buggy. I'm told to wait until the next day, that it might come back. I delete, uninstall, and reinstall the extension, but nothing works. And when, by some miracle, the screen appears, it tells me I have to log in to my LinkedIn account. I launched a campaign, the invitations were sent, but no messages were received."👎

In the ultra-competitive arena of B2B prospecting, choosing the right software can make or break your sales strategy. Kaspr stands out for its precision in data extraction and GDPR compliance, but its expensive credit model and limited automation hold back intensive prospectors.

Waalaxy shines with its multi-channel campaigns, combining LinkedIn and cold emailing, but its price increases and recurring bugs leave some users wanting more.

🚀And then there's Emelia, the revelation that is redefining the art of prospecting. With unlimited real-time LinkedIn scraping, 99% accuracy in email and phone number enrichment, and AI-powered automation, Emelia offers an all-in-one solution at an unbeatable price.

🎯Emelia doesn't follow the competition, it surpasses it, turning every click into an opportunity and every campaign into a success. Take advantage of free trials, test Emelia, and make LinkedIn your ultimate hunting ground!

1. Are these Chrome extensions safe to use with LinkedIn?

Yes, but caution is advised. Kaspr and Emelia emphasize their GDPR compliance and secure practices. Waalaxy, by modifying LinkedIn page code, can be detected, risking account restrictions or suspensions. Opt for tools with transparent privacy policies and monitor your LinkedIn account.

2. Which extension is best suited for small businesses with a limited budget?

Emelia excels with its affordable pricing and comprehensive features, ideal for small businesses. Kaspr quickly becomes expensive for intensive use, and Waalaxy offers higher starting prices, which are less suitable for tight budgets.

3. Can I automate multi-channel campaigns with these tools?

Waalaxy and Emelia offer multi-channel automation, combining LinkedIn and cold emailing. Emelia stands out with its Magic Writer for advanced personalization, while Waalaxy manages complex campaigns. Kaspr is limited to data extraction, without advanced automation.

4. How do these extensions handle GDPR compliance?

Kaspr and Emelia emphasize their GDPR and CCPA compliance, with clear policies. Waalaxy is also compliant, but some have concerns about its integration practices with LinkedIn. Check the certifications and permissions requested by the extension.

5. Which tool offers the best customer support?

Emelia shines with responsive support via chat, video, and personalized advice, often cited as a strength by users. Kaspr is effective for simple issues, but recurring bugs are annoying. Waalaxy offers good support in Europe, but response times can be longer outside the region.

6. Can I try these tools for free?

Yes, all three offer free trials. Emelia lets you test all its features at no cost for seven days, which is a great way to evaluate its potential. Kaspr and Waalaxy offer limited free versions, with full features reserved for paid subscriptions.
