Is there anyway to add/edit our email headers? I am not talking about the top of the HTML document, but the actual header information of the email (reply-to, etc.)
I know that the Email Editor gives Me Accress to From & Reply-to, but I have been advised that adding a List-Unsubscribe Header would possibly increase our deliverability with GMail, Outlook.com, and others.
Does Anyone know if this can be added?
Solved! Go to Solution.
Sorry, I think I miss understood the statement that had been made. I know that the list-unsubscribe had been added, but that a user could access it in Marketo to change it. I was hoping (based on 8058 doc https://datatracker.ietf.org/doc/html/rfc8058#section-8.3) that we could designate the on-click list-update in the header to unsubscribe from a particular list (section 8.3), not just the master unsubscribe activity.
Currently someone that clicks the list-unsubscribe gets unsubscribed from ALL our email products, not just from the list that the email they clicked the list-update is from. My dev team says that all we get from Gmail (for example) is someone wants to unsubscribe from one of our emails but not from which one, so they get unsubscribed from all.
My instance has a daily run OP program that was built years ago trying to address this by turning that unsubscribe value back to false but also putting the product field for the email list to false. Not ideal. Looking for an alternative solution so I can stop this bad OP program.
Ah, you can’t customize that header.
Note it’s questionable whether you should be resubscribing someone in this situation. That’s your call based on how your legal dept interprets the end user’s request to unsubscribe: did they mean all emails from that organization, all emails from that specific From: mailbox, all emails that relate to an underlying subscription concept, etc. The email client isn’t presenting those choices, of course, which is one of the weaknesses of List-Unsubscribe.
