Remove all subscribers from the master all subscribers list

Question

Is it possible to remove all subscribers from the master all subscribers list with a single request?

I understand that subscribers can be individually removed using DELETE https://www.exacttargetapis.com/email/v1/subscribers/[ID]

Issue with individually deleting subscribers is concern about rate limiting because of > 50,000 subscribers on list.

Answer 1

Pretty sure you can't delete all subscribers on the All Subscribers list all at once. If it was another list, you can delete the List Object, which will delete all of the subscribers in it.

Here's a sample SOAP envelope.
