How Can an Email Lookup Chrome Extension Help You?

Email lookups via browser extensions save time and bring better results to investigations. A reverse email lookup Chrome extension can save you plenty of time that would otherwise be invested in manually tracking down contact details for a series of different purposes. In some cases, such information would be nearly impossible to source manually.

Email lookup and reverse email search tools can:

  • find email addresses
  • verify email addresses
  • find additional information about the owner of an email address via data enrichment
  • source details about the online activity of an email address – its digital footprint

The find email address functionality of such tools is ideal for businesses that are looking to build up their contacts databases, whether for sales leads, networking, outreach, or any other purpose. 

The verify email address functionality, meanwhile, can ensure company contact databases remain up to date and check the validity of email addresses that individuals have provided.

By streamlining the process of finding and verifying email addresses, Chrome email lookup and reverse email search extensions can support businesses to implement effective marketing and sales processes, personalize email campaigns, undertake risk analysis, and help fight fraud through background checks that verify the credentials that customers or business contacts provide. If you need to use a Chrome extension to find an email address, verify it, and enrich your data, the products detailed above should prove invaluable.

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 extensions for the Chrome browser 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, and any organization that fraudsters could target – 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 add-ons as Chrome, since the two (along with 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 select the right option in the right-click menu to let the tool work its magic. Sometimes, depending on the tool’s settings, you may get results without clicking on anything.
