How do email lookup tools work?

Email lookup tools work by using a combination of algorithms, databases, and web scraping techniques to find and verify email addresses. 

When users input information such as names, domains, or company names, the tool searches its contact database and the web to match the input with existing email addresses.

As a next step, many email lookup apps verify the found emails by checking if the email servers are active and if the email follows the proper format.

As a result, users get verified email addresses.

How accurate are email lookup services?

An online email lookup tool is as good as the algorithms used to develop it. If accuracy is your highest priority, evaluate each option with a free trial or start with a completely free email lookup tool.
