Recent Email Bounce Responses
The Recent Email Bounces dashboard report presents data for various types of email bounces as a bar chart. The chart presents current bounce responses for the five most recent mailings that were sent before the current day.
The report contains the following bounce information.
Bounce type | Description |
---|---|
Mail Bounce |
The system cannot deliver the email and cannot positively characterize the delivery failure as either a hard or soft bounce. |
Hard Bounce |
The system cannot deliver the email because of a permanent problem with the receiving mailbox. For example, the destination mailbox does not exist. |
Soft Bounce |
The system cannot deliver the email because of a temporary problem with the receiving mailbox. The message might reach the intended recipient if you send it again. For example, the recipient mailbox is full. |
ISP Feedback |
The system successfully delivered the email message, but the Internet Service Provider (ISP) sent notification that the recipient reported the message as unwanted email (spam). This response is represented in the Detailed Bounce report as an abuse complaint. |
Out of Office |
The system cannot deliver the email because the recipient set an Out-of-Office reply for the destination mailbox. The message might reach the recipient if you send it later. For example, the message might be delivered after the recipient changes the mailbox status. |
Technical Issue |
The system cannot deliver the email because of a problem with the email infrastructure used to transmit and deliver the message to the recipient mailbox. |
Challenge/Response |
The system cannot deliver the email message because the ISP that received the email processed the message through a challenge/response SPAM filter. Challenge/response filters require human interaction to allow email delivery. |
Other |
Email messages were returned for reasons that are not categorized separately in the Recent Email Bounce Responses dashboard report or in the Detailed Bounce Report. |
Unknown |
The system cannot determine the reason why the email message was returned. |
Invalid address |
The system did not send the email message because the email address is not formatted correctly or is listed in the global email suppression list. |
