little green plane’s bounce smart reports allow you to identify the reasons behind your bounce emails.
 
Bounced emails are categorised into hard and soft bounces, in each case providing the details behind why an email has not been delivered.

An email that is unable to be delivered because of a temporary problem, such as a full mailbox is known as a soft bounce whilst one with a permanent error, such as an incorrect email address is known as a hard bounce.

little green plane will attempt to send your email to a soft bounce address eight times before it gets placed in your Do Not Mail file. We have three attempts at a hard bounce address before putting in Do Not Mail and flag these up in your failed export file.

There is no need to delete hard bounces as we will not allow any contacts flagged as one to receive your mailings again. If you delete them we cannot ensure this.
