The request delivery status is an attribute that provides more clarity and less confusion around the status of any request. Below are the different statuses that can occur and are visible in an export responses report:

• Not sent: suppression period: The email was not sent because this customer has already been sent a request in the past X number of days. This period length is defined for each company and can be updated in your settings.

• Not sent: do not send flag: The email was not sent because the API request defined do_not_send: true.

• Not sent: consumer unsubscribed: The email was not sent because this email address had been previously unsubscribed.

• Not sent: rejected: This email was not sent because it has recently received a bounce message in a previous attempt.

• Soft bounce: The email was sent, but may not have been delivered due to a soft bounce from the receiving email server. There will be an attempt to re-deliver. Soft bounces typically indicate a temporary delivery issue. While there are many reasons an email address may soft bounce, these are some common reasons this could happen:

  • Mailbox is full (over quota).

  • Mailbox is not configured correctly.

  • Mailbox is inactive.

  • Recipient email server is down or offline.

  • Recipient email server has been sent too many emails during a period of time.

  • Email message is too large.

• Hard bounce: The email was sent, but may not have been delivered due to a hard bounce from the receiving email server. There will not be an attempt to re-deliver. A hard bounce indicates a permanent reason an email cannot be delivered. In most cases, bounced email addresses are cleaned from your audience automatically and immediately. Cleaned addresses will be excluded from all future campaign sends. Here are some common reasons an email may hard bounce:

  • Recipient email address doesn't exist.

  • Recipient email server has completely blocked delivery.

• Sent: This email has been sent. There is not a way to confirm delivery into an actual inbox, but we have not received any indication otherwise from the mail server.

• Sent: unsubscribed: The email was sent, but has been subsequently been unsubscribed via this request specifically.
