Add to email blacklist?

[brianchance]

Is there any way to add an email to the email blacklist? Does unsubscribeByEmailFromAllLists add that email to the blacklist or just unsubscribe to all currently subscribed lists?

There is no endpoint to add to the blacklist as this affects all customers in a single instance, so you can't have customer a blacklist 10 emails which are also part of customer b and c.

You can write your own endpoint to do this if you wish, it should be simple enough.
