General

The recipient's email provider sent a hard bounce message, but didn't specify the reason for the hard bounce.

Important!

When UltraCart receives this type of bounce notification, we will immediately mark the recipient's email address as undeliverable.

(Sending messages to addresses that produce hard bounces can have a negative impact on our reputation as a sender. Continuing to send email to addresses that produce hard bounces, might pause our ability to send additional email.)

Permanent

Suppressed

The recipient's email address is on the Amazon SES suppression list because it has a recent history of producing hard bounces. For information about removing an address from the Amazon SES suppression list, see Using the Amazon SES global suppression list.

Transient

General

The recipient's email provider sent a general bounce message. You might be able to send a message to the same recipient in the future if the issue that caused the message to bounce is resolved.

Note

If you send an email to a recipient who has an active automatic response rule (such as an "out of the office" message), you might receive this type of notification. Even though the response has a notification type of Bounce, Amazon SES doesn't count automatic responses when it calculates the bounce rate for your account.

Transient

MailboxFull

The recipient's email provider sent a bounce message because the recipient's inbox was full. You might be able to send to the same recipient in the future when the mailbox is no longer full.

Transient

ContentRejected

The recipient's email provider sent a bounce message because the message you sent contains content that the provider doesn't allow. You might be able to send a message to the same recipient if you change the content of the message.

Transient

AttachmentRejected

The recipient's email provider sent a bounce message because the message contained an unacceptable attachment. For example, some email providers may reject messages with attachments of a certain file type, or messages with very large attachments. You might be able to send a message to the same recipient if you remove or change the content of the attachment.
