Many sites such as Jigsaw, Lead 411, and others charge a monthly fee. Also, LI InMail can be expensive.
Try Dun & Bradstreet (DNB.com) to buy email addresses with one time fees instead of monthly subscriptions. I get them for free using an automated combination of tools that allows me to target specific people. If that's something you want, request a 15 minute call, which will be enough time for me to walk you through the set up.
That depends on what you're trying to do. If its just to spam them, then buy a list. If its to actually speak with them, sign up on Linkedin or something similar (though Linkedin is the oldest and biggest of these professional networkign sites) and reach out to them or those near them.
Getting exact company emails is always something a lot of people are looking into. What I would suggest is trying to get the email address of somebody else within the company (maybe you have a friend there) or start searching for people in the company. A lot of companies follow a simple rule for creating email addresses:
* firstname.lastname@company.com
* firstletteroffirstname.lastname@company.com
etc. As soon as you know the name of one of the employees and start searching for combinations like this in your search engine of choice, you are bound to find a hit somewhere confirming how the email addresses are formed at that company. Based on that information you can figure out yourself what the email address would be of the person you would want to email ;-)
Google them using @, to find email address. Example, Michael T. Irvin @
Don't stop taking massive action.
