There are many potential reasons you didn't get a response, but I want to highlight one in particular: There was no value proposition in this email. For an email like this to be worth responding to, you have to provide a brief, no BS, explanation as to what compelling value you're bringing to the table. The only exception to this rule is if you're famous for your accomplishments in that specific role (in which case, they're probably pitching you already anyway). Finally, nobody owes anyone a response to a cold-call email. Especially not people that get hundreds if not thousands of emails a day. Don't take it personally.
