I have a small B2B newsletter that I moving into my Marketo instance. The data is not synced, so we have to manually add a static list every quarter when the newsletter goes out.
The issue is that there are people on the static list that have unsubscribed in our previous platform. The source of our data does not manage unsubscribes, so we've always had to manually manage this to comply with CASL.
My question are:
1. If I upload the unsubscribed people in a one-time static list with their preference set as unsubscribed is true, will I have to do this every time I add a new static list? (note: our static list does not indicate preferences)
2. Is there a faster/more efficient way to manage it?
Appreciate your help!
