A carefully calibrated system taking into account industry standards will temporarily unsubscribe recipients who, in a given period of time, will return a number of consecutive bounce for the same reason, without having had recent activities. This will let help customers to automatically follow the best practices and avoid to continue sending to email addresses that can not receive communications.
At the end of the temporary unsubscribe the recipient will be automatically re-entered as subscribed. If a further bounce for the same reason is returned, the recipient will be unsubscribed temporary temporarily for a period of time slightly longer.
Subsequently, if the in box of the recipient continues to be unreachable it will be classified as "permanently unsubscribed to further bounces."
Although it is possible at any time to force the re-submitting, it is not reccomended highly recommended to not do it untill it do so until the reason has been clarified and resole the motivation for not delivering the message has been resolved. Otherwise the recipient would be unsubscribed within the from further sending.
