Chrome Extensions can add a boost to your productivity, but if you are not using the right one for what you need, they can be a major time waster.

As you may know, Google Chrome is the most popular web browser. In fact, almost half of all users are using Chrome over Safari or Internet Explorer. That’s because it’s easy to use, syncs with most mobile devices, and is fast. But the other reason it is so popular is because of Chrome’s extension capability.

Of course, there can also be too much of a good thing. If you use too many Chrome Extensions, your computer can become clunky (at best), or completely non-responsive at worst. That is why you need to choose your extensions wisely.

This year, the Lusha team had a 3rd party company compare the eight (8) most popular chrome extensions used for finding contact information: Lusha, Connectifier, Prophet, Hunter, FindThatLead, Hiretual, Contactout and JobJet.

There are lots of tools that want to tell you that they are the best, but there are few that are willing to show you that they truly ARE the best. Lusha dared to compare and find out once and for all. Below you will find the Chrome Extension performance report.

A Comparison of the Top 8 Extensions to Find Contact Information


Browser extensions are a natural choice for most of us when trying to be more efficient and productive. However, with a slew of new extensions continually being created, it’s hard to weed out the really great ones.

Instead of cluttering your browser with tons of extensions, we decided to test the top extensions for finding contact information and see which came back with the most results. To see the complete results (including the info found for each), go here.

Lusha decided to research the best methods of getting in contact with potential applicants because many of their users have stated their dissatisfaction with the results they receive when using inMail. In fact, the Marks Group — an IT, Sales, and Marketing Recruiting firm — conducted a study and found that “The response rate is typically somewhere in the 15 percent realm. That’s only about 1 out of 7 responding! Doing the math, on average, people sending lots of InMails will spend more than $30 per response!”

So, since the results from using InMail are not great, we decided to test eight (8) extensions that can replace LinkedIn InMail as the best means of contact.


We compared the top eight (8) extensions for finding contact information against 300 random LinkedIn profiles and recorded our results.

Search Criteria

We started by choosing three different job titles to search for — Investment Bankers in New York, Product Managers in San Francisco, and Corporate Lawyers in London. Then we picked a random sample of the first 100 people in each job category to perform the test on.

Search Categories

We choose to test the extensions to measure the following conditions:

  1. No results (The number of times the extension brought back zero results for a profile (not one piece of data among the four categories tested);
  2. Private emails;
  3. Work emails; and,
  4. Phone numbers (personal and corporate).

Sometimes, the extensions found more than one result per person, say, if the person has several numbers or emails, which is why some results in the following categories add up to more than 100: Private Emails, Work/Other Emails, and Phone Numbers.
