LinkedIn is definitely the most powerful tool for lead generation, but it can be further amplified with email-finding tools such as ZeroIn.
Most often, you won’t be able to find a business email address on a lead’s LinkedIn profile. That’s where ZeroIn fits in.
You can install it as a browser extension, visit the lead’s LinkedIn profile (or even the Search results page for bulk matching), and ZeroIn will search its 200M database to match the contact data to the LinkedIn account.
