ok, what you could do on that part:use an enrichment to look up if the segment existsthen split up the workflow depending on the "new" or "update" paths

You may use the function FileName($(vars/@filename))

for the mobile app, the tokens are "synced" to ACS from another Adobe service.Can you verify e.g. in the logs of Android Studio that the calls to Adobe are all really done? (1 for ID sync, 1 for registration in ACS)Also ensure that the IMS Org is the same for the app and ACS

Yes, you can also import records via a workflow.Just check for addressStatus table. The Quarantine records are not linked to the profile and will also remain in the DB once the profile is deleted.

Unfortunately there is nothing better available at the moment

Unfortunately no.You can't trigger a workflow in real-time for unsubscriptions.Only way is a scheduler which you may set to 10 minutes (or more)

Yes, as stated in the post above the 1 = 1 is not working when I did a quick test What you need to do:In both paths add an EnrichmentAdd Value = 1, Name = @expr1Then use @expr1 in the join criteria

You can reach it in the menu as stated by John.For doing so, you will need to have the Deliverability permission (just Administrator role is not enough here) Note: be careful on the brand configuration, especially on E-Mail and domain fields.Some wrong settings may cause mails not being sent anymore

suresample workflow overview:Workflow overviewPrimary set = query on profiles:Then add the load file schema as advanced relation with a join.Note: doing a quick testing the 1=1 join is not feasible here. Instead you need to add a variable e.g. expr1 on both paths via Enrichment and then use it hereU...

This indeed has to be done before the E-Mail sendout is completed.It can't be done afterwards anymore
