We would like to have the MID added to the subject line of our shipping notification emails that are automatically sent out.
We send those out for both of our gift card providers that we order from "CMS" and "CFS" They are titled "CMS Shipping Notification" and "Shipping Notification" I can email examples when needed.
Gift card orders, can go to two different companies, want to add the MID to the subject line. It's currently not available to the user. Next month is their busy season.
