How to Choose an Email Lookup Chrome Extension 

The best email intelligence chrome extension for you depends on the needs you are looking to satisfy. In some cases, it may be beneficial to use more than one of the above to supercharge your results. 

One last piece of advice: When there is a free or trial version available, make sure you give it a go before committing. 


What is an email lookup Chrome extension?

These are extensions for the Chrome browser that gather and display information related to an email address, either by starting with the email and adding more data, or by sourcing email addresses for specific people or organizations.

Who uses email lookup on Chrome?

Companies and professionals who can benefit from such functionality include marketers, salespeople as well as any organization that can be targeted by fraudsters – which, in 2023, is every organization.

Are there email intelligence extensions for other browsers?

Edge users can, in many cases, use the same extensions and addons as Chrome, since the two, as well as other browsers, are based on the open-source Chromium architecture. Firefox and Opera users can also try to run the above, as well as look in their respective app stores.

How do you use email lookup Chrome extensions?

Chrome extensions are delightfully simple to use, usually just requiring a quick installation from the Chrome Web Store – though with some of the options above you will need to set up an account with the vendor first. With the extension installed, you normally need to click an icon in your toolbar or the right option in the right-click menu to let the tool work its magic. Sometimes, depending on the settings of the tool, you may even get results without needing to tap on anything.
