Looking for some feedback on how customers are setting up their campaigns.

Is anyone using one open-ended campaign and using the same APR until the supplier asks to be removed?

Is anyone using yearly campaigns and adding the same supplier every year to give them the option to opt out ?

Setting up campaigns is very manual work so would appreciate hearing how you are using the product and what has worked well for you.
