What’s a good frequency when your goal is to start raising awareness with new people?

Three per day — build awareness, but don’t waste budget on unneeded reintroductions.
Ten per day — spend some extra so they remember you.
One per day — you’re just trying to meet new people.
Unlimited — make sure they remember your brand.

The correct answer is:

Three per day — build awareness, but don’t waste budget on unneeded reintroductions.
