search email id of CEO of www.tutsys.com

what you need to do is get the name of the CEO from the website. For
example say its John Roberts. Then you need to go to google and do a
search for "@tutsys.com" email. he search results will throw out a lot
of email ids of employees working or have worked in Tutsys with their
email ids like myra.johnson@tutsys.com OR mjohnson@tutsys.com etc.
What you need to do is understand the email signature logic and put
the CEO's email in the same way. For example if you see all the emails
following the patter which is xyz.abc@tutsys.com; replace the xyz.abc
with the CEO's name and you have his email id
