We would like to see this feature implemented. It will help us keep our contacts database clean. Imagine a scenario where a company reaches out to a contact with occasional offers. They don’t respond or unsubscribe. We might remove them from our mailing list after 12 months and archive them (they don’t qualify as a Subscriber or a Lead). But if they reach out to us, or we find them via another network and they are interested, we’ll reactive them. I’d like to know what we tried to engage them before.
