One-Click List-Unsubscribe in ACS

Avatar

Level 3

Hi,

 

We have previously set SMTP headers to support list-unsubscribe. For example:

 

Precedence: bulk
List-Unsubscribe:<mailto:bounce@123.xx?subject=unsubscribe<%=escape(context.mimeMessageId) %>>
List-Unsubscribe-Post: List-Unsubscribe=One-Click

 

Now I saw about modifying SMTP parameters could break the OOTB One-Click List-Unsubscribehttps://experienceleague.adobe.com/en/docs/campaign-standard/using/administrating/configuring-channe... 

 

So my question is how to set the SMTP headers to be compliant with the One-Click List-Unsubscribe requirement from Google and Yahoo!?

@filipe23353816 If you have a stage instance can you take a look at the OOTB delivery template named "Send via email" and refer to the SMTP section. That may have the header details that you need. It may look like below,


<% if( context && context.profile ) { %>List-Unsubscribe:<<%@ value object="branding" xpath="@serverUrl" %>/lp/bl?pkey=<%=escapeUrl(context.profile.PKey)%>&OneClick=true>,<mailto:<%= context.delivery.mailParameters.replyAddress %>?subject=unsubscribe<%=escape(context.mimeMessageId) %>><% } %>
<% if( context && context.profile ) { %>List-Unsubscribe-Post:List-Unsubscribe=One-Click<% } %>

 

You may have to copy this to the template that you're already using and test it out before deploying it to the emails.

Thanks, Sathees

That does not seem to work when I try. I don't get the unsubscribe link in Gmail and also when I try to access the link it says 

 

BAS-010096 Error return code : -2003

@filipe23353816, I would suggest opening a support ticket to figure out why it's not working. Meanwhile, I will check and let you know about this.

Hi,

 

Managed to solve it with some further investigating. I hadn't published the "bl" landing page that the link in the https variant was referring to. So when I did that the link worked and I also got the unsubscribe link when I did a real sendout.
