Cleaning Basics
Cleaned is a Tatango term that means a phone number on your list has been automatically unsubscribed, as we've determined that future messages to that specific subscriber will not be received.
The reasons why a number gets Cleaned varies greatly, but a few examples would be that the subscriber's wireless carrier turned their service off, the subscriber placed a block on short code messaging, etc.
How Cleaning Works
When a message is sent to a phone number, Tatango receives a response from the phone's wireless carrier, telling us if the message was received or not by the phone. If your message wasn't received, Tatango will designate that message as a Bounced message. If the bounce is a "hard" bounce, Tatango will immediately and automatically unsubscribe the phone number from your list. If there are seven consecutive "soft" bounces, Tatango will immediately and automatically unsubscribe the phone number from your list.
