Is there a way through either AMPScript or SSJS to manipulate custom content inside the email sends through the Marketing Cloud? For example, say I want to add information for 'List-Unsubscribe' into the header to allow for an automated unsubscribe process, would I be able to do this using server side code on the email?

Everything I have seen referenced in the SSJS and AMPScript functions does not seem to mention any capability of this, but thought I could ask as maybe I am missing something.

If I cannot add through scripting, what would be the best way to approach having this added in?

  • What do you mean by automated unsubscribe process? AMPScript and SSJS are evaluated at send time or at each view on a landing page, once it hits the inbox or the landing page loads, it's set. Aug 3 '15 at 14:07
  • in the email header if you include information for "List-Unsubscribe" then clients will offer an unsubscribe option right alongside the spam button. This helps alleviate potential spam complaints by having them just click unsubscribe instead. - I want to be able to add this info into the header, but cannot find a place to add this in.

  • What email clients support this? I've done some work with Google Actions, but nothing that's like List-Unsubscribe. Aug 3 '15 at 14:34
  • According to this blog post, ET/SFMC emails support this already. Aug 3 '15 at 14:41
  • I know gmail has it, windows live and a couple others. I believe potentially all Outlooks may be getting this as well. Here are a couple links with more info: list-unsubscribe.com and another about gmail: marketingland.com/… Aug 3 '15 at 14:41

Sorry for the refresh on an old post, but I thought it might be good to provide an answer here - This was an issue that was on Salesforce's end (something to do with the way their permissions were set up on the back end). We went through around 3 months of back and forth with their developers before they realized that the permission set we had SHOULD include this, but did not. I believe we had the Sender Authentication Package with multiple IPs. They updated it and have told me that the permissions are now in place to include the unsub header.

    Yeah - thanks I completely forgot to come back to this. I heard basically the same thing from support. They 'magically' made it work when they 'tested' it. May 19 '17 at 13:05
