Email extractors make it easier than ever, however LinkedIn has banned certain services and plugins for their ‘growth hacking’ features. For example, Hunter.io was one of the most popular extractors until LinkedIn banished them in 2017.
For now, you might try the SignalHire Chrome Extension, because it extracts both personal and business emails from LinkedIn.
As opposed to other extractors in the market, SignalHire doesn’t just generate work emails using most common email patterns in a company; it also finds and verifies emails across the WEB in real time. This way emails are always fresh and accurate.
In addition, the extension finds cell/mobile and office phone numbers.
