Seriously, the five most important things about marketing for your event

1. Stick close to your key messages

2. Repetition, repetition, repetition

3. Overlap your marketing tactics so that the target market hears your message from several sources

4. Keep it short

5. Personalize when you can

Do those five things and you will be way ahead of pretty much everyone else (and, yes, we will go into a lot more detail in the coming days/weeks/months).
