I've tried direct mail, but got no response (I don't think my mailer even got to their desks). I considered LinkedIn Ads, but then I read that few CEOs even visit there very often. I could try email... Is there something I'm missing?
It's about providing value to them.
You're right, likely your mailer never made it to their desk.
One of the nice things about LinkedIn ads is you only pay when they see it.
I think LinkedIn is a great starting point; but it is a process that cannot be automated. It is an investment of time to build a relationship and prove value.
I help entrepreneurs like you develop a strategy to accomplish goals like this. I'd be happy to discuss further. Book a call and let me know when you're ready to get started.
