Sending an email to someone you’ve never met before and looking for a response — especially if that person is an important executive — is something of a gamble. The odds are overwhelmingly stacked against you, but if you play your cards right, you could score a win.
CxOs are remarkably accessible and very easy to reach. Most CxOs read every email they get personally … even cold emails (though they usually don’t reply). And it is easy to guess the email address of 90% of company CxOs (it usually follows the company convention for email addresses).
Of course, just because a CxO will read your email does not mean your email is worth sending. You should try to only send emails to people (whether it be big-time CxO or an entry-level person) that they will benefit from … you want to remain relevant.
