The marketers in our organisation would like to be able to add Salesforce contacts to a Marketing Cloud suppression list in order to avoid emails being sent to them.
The emails are being sent by a Journey that collects data from a Data extension that is populated by a Marketing Cloud Automation + API integration.
The contacts in the Marketing Cloud data extension are but a mirror of the Sales Cloud since the are both being synced by a similar process, so we can assume they are aligned.
So, at the end of the day, what would be the best approach for this? Checkbox + trigger? Any custom configuration?
Thanks in advance!
