Email Delivery Error Categories

Email delivery error categories

When an email is not successfully delivered by Elastic Email it will be grouped into one of the following categories. Below are descriptions of each category we currently support.

Ignore

The email was not delivered because the email address is currently in the "Bounce List". Emails in the "Bounce List" are either hard failures or unsubscribes managed by our system. If you feel this email should be delivered please go to the "Bounce List" tab and remove the email address from this list. Emails in this category are not rescheduled. Please see the detailed error message for more information about the specific email problem encountered.

Spam

The email was not delivered because the recipient server or user has flagged this email as spam. Emails in this category are not rescheduled. Ensure your emails are following the CAN-SPAM guidelines and see our Blog for topics on spam. Please see the detailed error message for more information about the specific email problem encountered.

GreyListed

The email was not delivered because the recipient server has determined that this email has not been seen in the configuration provided (most often the combination of IP, From Email Address and Recipient Email Address - known as a "triplet") and has temporary rejected the email knowing that valid email will typically be retried. Emails in this category are rescheduled automatically in a priority queue. Please see the detailed error message for more information about the specific email problem encountered.
