Definition

When someone explicitly gives permission to receive marketing communications, theoretically because they actually want them. A legal requirement dressed up as customer courtesy.

Example Usage

Our opt-in rate is 12%, meaning 88% of people would rather die than receive our newsletter, which is honestly fair.

Origin

Emerged from email marketing best practices and anti-spam legislation in the 1990s

Fun Fact

GDPR made opt-in mandatory across Europe, instantly decimating email lists and causing marketers to mourn their lost spam privileges.

rhetoric

clickthrough

The holy grail metric of digital advertising that measures whether anyone actually bothered to click on your carefully crafted ad instead of scrolling past it in disgust. It's the moment when a user's curiosity (or accidental thumb slip) converts an impression into an action, causing marketers everywhere to briefly celebrate before realizing the bounce rate is 98%. Ad agencies live and die by clickthrough rates, which explains why banner ads have become increasingly desperate and annoying.
