Since HTML's humble beginnings, the "click here" call to action has been ubiquitous in both email and web copy, and has become so common that "click here" has lost its meaning in more ways than one.
CTA is no longer just about clicking. If you consider the variety of settings in which online content is consumed, the assumption that we should only be clicking is a silly one.
Back in those days, "device independence" largely meant creating content that was just as relevant to the reader on paper as it is on screen. Now, when emails are routinely read on devices that are navigated using taps, voice commands, shakes, swipes, and styluses, "click here" seems increasingly outdated, and at the very least, it's lazy and unoriginal.
