Hello @CJara1 , In this case, I feel, first, you need to identify the
type of ID which you want to target whether it is Device ID or Customer
ID.3P generally provides Device ID and if those IDs have less overlap
with your company's own device base then conversion would be always
low.I would say using a 3P data source that gives you more overlap is
something you should use while findings the prospects. I hope this gives
some direction! RegardsAnkita Sodhi
