Allow Channel Level Opt Out to be sent
I'd like to find out where the channel level opt outs are being excluded from a delivery, there doesn't seem to be a rule in the default typology I am using yet they are taking place.
We have a use case to allow marketeers the ability to contact recipients who have opted out of SMS (@blacklistmobile) with service or informational comms. However if they are flagged as 'Do Not Contact by Any Channel' (@blacklist) they should continue to be excluded.
If I untick the blacklist option in the delivery (To > Exclusions) then all comms are sent regardless of the opt out preferences in either the SMS level Opt Out (@blacklistmobile) or the 'Do Not Contact by Any Channel' (@blacklist) field.

A solution would be to untick the blacklist box, and then create a new typology rule which would then reapply the @blacklist opt out preferences. This would allow channel level opt outs to be sent whilst excluding the @blacklist level opt outs, however I'm convinced there is a simple OOTB answer I've missed, I look forward to finding out I'm correct!
