GetProspect is a generation tool with an email finder. Just select your search criteria and the tool will give you a list of leads with names, corporate emails, position, LinkedIn urls, company name, website, industry and more.
We like how you can harvest and enrich LinkedIn profiles across multiple search pages of a search query on LinkedIn.
The guys at SmartReach.io have created a pretty cool plugin for LinkedIn and Gmail. Find contact details while browsing LinkedIn, or directly within gmail as you are composing a new message.
We think the Gmail email finding feature is pretty cool, and definitely unique. If you use Gmail a lot, and outreach to many people on a case-by-case basis, we'd recommend it!
