(Tcl) Send HTML Email with CSS as Related Item using Content-LocationDemonstrates how to compose an HTML email with an external CSS file included as a related item and referenced by Content-Location. Some email clients display embedded (related) content best using CID's (Content-IDs), whereas other email clients display related content best by Content-Location. The choice you make may depend on the software used by the intended recipient of your email. (Does' the recipient read email on an iPhone? Android? Outlook? GMail? Thunderbird? etc.)
