To assign a campaign, set a meta tag of the type name with the value X-Mailjet-Campaign and
set its content to the name of the campaign (for example: invoices).
You can make this setting in the Email section properties (see "Meta information" on
page185).
Alternatively you could write a Control Script, for example:
merge.context.sections["Content"].addHeader("X-Mailjet-Campaign",
"invoices");
Note
Mailjet strips out their own mailheaders like X-Mailjet-Campaign. The results can only be

> All.
