I was facing the issue of importing a list to "All Subscribers" with the status Undeliverable. The problem is that the keyword "Undeliverable" do not exist in order to update the subscriber status. I've tried with "Held" and "Bounced" as well but doesn't work (error "InvalidContextStatus Invalid Context Status").
Anyone know what is the status to update the subscribers?
I know that using API calls we can do it (https://developer.salesforce.com/docs/atlas.en-us.noversion.mc-apis.meta/mc-apis/subscriberstatus.htm). But in this case, I would like to update the status with bounce using import.
