Deconstructing Return-Paths

Deconstructing Return-Paths

Overview

Let’s deconstruct the example SendSage Studio generated Return-Path (bounce address) below:

return-a31-271-272-recipient=customer.com=4@example.com

It consists of eight parts:

  1. return – The localpart of the bounce mailbox that SendSage Studio used.
  2. a – The prefix that SendSage Studio prepends to ListIDs. This prefix is used to distinguish SendSage Studio generated messages from messages that were generated from other sources. This field is set equal to a by default.
  3. 31 – This is the ListID that the message was sent to.
  4. 271 – Stat ID – This is an internal value that we use to determine where to put the stats for this bounce.
  5. 272 – Stat Slice ID – This is an internal value that we use to determine where to put the stats for this bounce.
  6. recipient=customer.com – The VERP encoded email address of the subscriber that this message was sent to. This example Return-Path is from a message that was sent to . See the Raw Injection Headers page for more information.
  7. 4 – Indicates that this is Return-Path was generated by SendSage Studio.
  8. @example.com – The domain name portion of the bounce mailbox that SendSage Studio used.

Web Interface Lookups

Once you’ve identified the subscriber ID and ListID, you can lookup information about the mailing list or subscriber.

To lookup information on the mailing list, go to the following URL:

  • http://HOSTNAME/ga/mailing_lists/LISTID/

The following replacements will need to be made:

  1. Replace HOSTNAME with your SendSage Studio server’s hostname.
  2. Replace LISTID with the ListID.
