Our Marketing Cloud hierarchy consists of 170 child business units and a single parent business unit. Local marketing emails are sent from the 170 child business units.
We track opens and clicks in the mails sent from the child business units and sometimes - based on those interaction - we send subscribers on journeys from the parent business unit.
So, as a SFMC Admin I want to query subscribers on ie. a product journey into a suppression list for my users in my 170 business units to pick as optional suppression lists when sending either a single send email or a multi-step journey.
The reason for me trying to use suppression lists for this is that I want these to be optional no matter if the local marketeer is using the single send available in Email Studio or using Journey Builder.
The reason for me using suppression lists and not auto suppression lists is that I want this to be an option for the local marketeer to be in control of.
I know how to query data into data extensions and update these using Automation Studio. But suppression lists are totally new to me.
How can I use Automation Studio to constantly refresh these suppression lists?
