Is there goping to be an 'unsubscribe many' API option any time soon, as this would greatly speed up our ablility to syncronise our own system with CM quickly (300+ lists 120,000+ unique subscribers)?
Yeah, that would be a nice feature. Or even better would be a option to let CM unsubscribe direktly. Let us save an URL per client which gets a request every time a user unsubscribes.
We would be interested in this feature too as it will reduce the number of calls we need to make to the API when unsubscribing people on behalf of our clients.
