I’ve worked as both a head of marketing and a product lead, but sometimes the two are absolutely separated and viewed as completely different domains and disciplines.

This is a fallacy.

Marketing is a product.

Your marketing strategy/rollout is a cohesive creation, including brand, messaging, content, etc., but also built on top of multiple platforms: CRM, email engines, analytics, optimization tools, content platforms, and so on.

Products are a mix of feel, form, and function. Like any product, your marketing is designed to reach and please a customer, to bring them into your world, and to be useful. Every human who’s reached by your brand anywhere is using a product from you already. When you find a feature that doesn’t work, you adjust that feature.

Marketing is a product.
