How to Find Email Addresses on the Internet, Part 1

Last week, I had the opportunity to be on the Recruiting Animal Show. Towards the end of the show, a caller asked me how to find personal email addresses on the web. I answered the question, but because there are so many ways to tackle the issue, I thought I should follow up with a series on finding email addresses. To start, I am sharing a list of resources and techniques that will help you find business email addresses. – Linksy is a great place to start when searching for email addresses. Linksy generates possible email addresses based on a persons name, then cross-references those names with to see if the person has a gravatar account with a photo. If the person has a gravatar account, one can simply use that email address and initiate contact. If the user does not have a gravatar account, Linksy has generated a list of possible email addresses that can be tested using one the tools below.

Rapportive (free)– Rapportive for Gmail is a tool that has been mentioned previously on SourceCon.

  1. Nice article. The best tool I’ve worked with recently is Connectifier: If there is an email address linkedin to (social media) web page, it is visible. Rapportive could work when no details are available, Connectifier helps you to skip a few steps.

  2. To run batches of email lookups, you can use This tool allows you to take a CSV of first name, last name, and website domain, and it will find the best email for that person. Saves a lot of time and is great for B2B prospecting.

  3. I love this Rapportive idea. I’d like to point out that in recent months there have been a number of new apps and tools which take this idea to the next level.

    One such example is eMail Prospector tool, ( Free trial run – ) where it does all the hard work for you. You just need to know the first and last name and company they work for and tool gives you verified business e-mail.

  4. Will definitely check out some of these sites. Thanks for sharing. If you use Chrome, FireFox or Safari, is also a good one. – Sandra, founder at
