Tool No 1
Linksy(dot)me : The service checks the e-mail addresses it generates against Gravatar, and if they have a Gravatar account, it displays the blogger’s picture. Even if the person’s face didn’t pop up on Linksy doesn’t mean that e-mail address isn’t right — it just means that he/she does not have a Gravatar with that e-mail address.
Tool No 2
Use Rapportive which is a plugin which you can add to Gmail. It adds a sidebar that shows information about someone as soon as you enter the person’s email address. It is an amazing tool as you just need to hold your cursor over each e-mail address to see if one of them shows linked social profiles.
Finding the email is a sure way to get a response from the individual whom you want to contact.
