How does it find this data?

Kaspr's extension uses a combination of its extensive proprietary database, publicly available information scraped from company websites and LinkedIn profiles, and data from third-party providers. It boasts real-time data verification from over 150 sources to ensure accuracy.

This collected information can then be exported directly to popular CRM systems.

While the extension is free to download and install, you need a Kaspr account. The free version offers very limited credits, making it suitable mainly for individual users or testing purposes before committing to a paid plan.

Key benefits of the Kaspr Chrome extension

Kaspr's Chrome extension is a powerful tool that offers several advantages for sales and marketing professionals:

  • Strong data coverage: Kaspr provides access to contact details for over 200 million profiles, with a particular strength in European markets.

  • Real-time verification: The platform cross-references data from over 150 sources and performs real-time verification checks, aiming for high accuracy.

  • CRM integrations: Kaspr supports integration with CRM solutions like HubSpot, Pipedrive, Salesforce, Zapier, and Zoho. That makes it easy to export contact details to your CRM and enrich lead lists.

  • User friendly interface: The extension is generally considered easy to install and use. Once set up, you can visit any LinkedIn profile and click the Kaspr widget to access contact details. These leads can then be managed on the Kaspr dashboard.

  • Compliance: Kaspr is CCPA and GDPR-aligned, making it easier to comply with privacy laws when building lead lists.

Potential challenges with the Kaspr extension

Despite its benefits, especially for targeting European markets, Kaspr has drawbacks. Users should be aware of these common limitations:

Common limitations include:

  • Data accuracy issues: While Kaspr uses real-time verified data from 150+ sources, many users report struggling with incomplete or outdated contact details, according to G2 reviews.

  • Restricted free plan: The free tier offers only 5 phone credits and 5 direct email credits per month and doesn't support Sales Navigator integration, which is insufficient for most active sales teams.

  • Triggers LinkedIn warnings: Some users on G2 report that LinkedIn flagged their profiles for suspicious activity after installing the Kaspr extension.

How to install Kaspr extension

Getting started with Kaspr involves installing the extension and connecting it to your LinkedIn account:

  1. Visit the Chrome Web Store and search for the Kaspr extension.

  2. Click “Get” and follow the prompts to install the extension. You'll see a confirmation once it's added.

  3. Click the Kaspr icon in your browser's toolbar. Log in to your existing Kaspr account or sign up for a new one (a work email is typically required).

  4. Navigate to LinkedIn. Open the Kaspr extension widget again. It should prompt you to connect; click “Let’s Go” to sync Kaspr with your LinkedIn account.

While Kaspr is a solid tool, its data limitations or pricing might lead you to explore alternatives. Here are a few popular options:

PhantomBuster

Kaspr Chrome extension FAQ

Can I access contact data with the Kaspr extension?

The Kaspr Chrome extension offers access to emails and phone numbers as you browse different LinkedIn profiles. You can access a prospect’s email address, phone number, and company details when you visit their LinkedIn profile.

Does Kaspr work with my CRM?

Kaspr integrates with widely used CRM platforms, such as HubSpot, Pipedrive, Salesforce, Zapier, and Zoho. It allows you to automatically send enriched lead data to your CRM. If you’re using a different CRM system, you can still connect it to Kaspr using Zapier.

How does Kaspr get phone numbers and email addresses?

Kaspr mix of its own database, public data scraping (like company websites), third-party data providers, and real-time verification across 150+ sources.

Is Kaspr.io free?

Kaspr offers a free plan, but it's very limited: 5 phone credits, 5 direct email credits, and 10 export credits per month. Paid plans starting at $49/month are needed for significant usage or advanced features like Sales Navigator support.

Is Kaspr Chrome extension safe?

Kaspr states it is CCPA and GDPR-aligned. It vets data providers and primarily retrieves publicly available information. However, users should be aware that any tool interacting heavily with LinkedIn carries a small risk of account flagging, as reported by some users.

What's a good alternative if Kaspr isn't the right fit for me?

Choosing the "best" alternative depends on your specific needs. If Kaspr's data limitations or focus primarily on retrieving contact info aren't quite what you need, PhantomBuster is a strong contender, especially if you're looking to automate more of your sales prospecting workflow. While Kaspr excels at quick lookups via its extension, PhantomBuster focuses on automating tasks like finding leads based on specific criteria, enriching profiles with AI, sending connection requests, and even scheduling messages.

It's geared more towards streamlining repetitive outreach and data gathering tasks across the entire process, rather than just point-in-time contact finding.
