Kind of depends on who those 120,000 people are, doesn't it?

Ask yourself what they have in common. And ask yourself what it is they want ... or would want if they knew about it.

Then figure out what you can give them that (1) closely matches what they want and (2) can pay you for your time.

Don't look at this as a short-term sales pitch, a single email blast leading to 1 transaction. Rather, look on it as your chance to build up to 120,000 ongoing relationships with new people.

Before you try selling them anything, introduce yourself. Pretend that you're talking to an individual. Present yourself as a brand and as a person. Explain the ownership change. Explain your tentative plans and what you hope to offer them. Ask for feedback. And listen to it. Those who engage are your audience – not the full 120,000, who have mostly moved on by this point, I imagine.
