My Pinterest Partner is telling me to optimize my ads using traffic campaigns

I am running $350 of a traffic campaign a day.

This was recommended to me by the partner that you get with Pinterest when you join as a brand TRYING TO SELL A PRODUCT.

The optimizing partner has set up a traffic campaign for me, telling me to run it for a week to collect data and then we would optimize it together this Monday. I am spending money, but getting absolutely no conversions.

Are they just trying to make me throw money away?
