We imported approx. 50K records into the DB that we want to be able to treat separately (for now); ie: not included in DB-wide blasts, yes, able to send to as an isolated group.
To accommodate this I created a custom field named "Origin" and entered the same value in this field for each record when I imported this subset into the DB. Everything's fine so far. My question pertains to going forward.
As a custom field, this column in a smart list can't be sorted. I wonder if I should've used the stock field: "Original Source Info" instead -- as its values can be sorted, or is that field used for something else?
