Does Adobe support X-HEADERS ?
We are seeing inboxing results for our campaigns splitting up and want to make use of custom headers.
We want to Identify a X-HEADER that can be used to store a unique campaign identifier.
How can we use the XPVIQ code within the delivery header in ACS?
@mmbb110I think it should support x headers. Please refer this post for ACC where x-headers are used: https://experienceleaguecommunities.adobe.com/t5/adobe-campaign-classic-questions/adding-headers-to-...
Additional SMTP headers: This option allows for additional SMTP headers to be added to your messages. The script entered in the Headers field must reference one header per line, in the form of name:value. Values are encoded automatically if necessary.
