Chanel is sponsoring Substack writers, joining a wave of beauty brands that now treat the newsletter platform as a genuine media channel rather than an experiment.

The move signals a shift in how luxury beauty reaches consumers. As Substack matures, brands are partnering with its most trusted writers to build what industry observers describe as a more intimate form of audience engagement, according to a Business of Fashion analysis titled "Why Does Chanel Need to Sponsor a Substack?"

The traditional launch playbook no longer guarantees attention. For a new scent, luxury labels have long relied on a familiar formula, as BoF put it: "Cast an impossibly beautiful celebrity, throw them on a horse and host a lavish party (or two)."

That playbook is under pressure from two directions.

Why is the old fragrance playbook breaking down?

The economics of growth marketing have deteriorated. Growth marketing has become more expensive in a crowded market, and beauty leaders must now rebuild their creative marketing muscle and make bold choices, according to BoF's report "The State of Fashion: Beauty Volume 2."

Distribution has shifted decisively online. More fragrances are now sold through digital channels than in store, according to the analysis. That undermines the traditional "try before you buy" model that depended on physical retail and in-person sampling.

New channels are accelerating the change:

• Amazon continues to gain speed as a fragrance destination
• TikTok Shop is picking up momentum in beauty sales
• Brands must adapt to a reality where the point of purchase often precedes any physical encounter with the product

What does Substack offer that celebrity campaigns cannot?

The answer, according to BoF, is trust at scale. Substack writers bring direct, subscription-based relationships with readers who opted in. A sponsorship placed with a trusted newsletter voice reaches an audience already primed to listen — a contrast with saturated paid social, where costs keep climbing and attention keeps fragmenting.

For a house like Chanel, the calculation is notable. A brand built on heritage and exclusivity is spending media budget on a platform associated with independent journalists and essayists. The sponsorship format lets the brand borrow credibility from writers rather than lend it to celebrities.

BoF frames the broader trend plainly: as the platform matures as a media channel, "a slew of beauty brands are turning to its most trusted writers for a more intimate form of audience engagement."

What comes next?

The sponsorship trend suggests beauty marketing budgets will keep migrating toward owned-audience and creator-media hybrids. If digital fragrance sales continue to outpace store sales, expect more luxury houses to follow Chanel into newsletter partnerships — and to treat writers' subscriber lists as seriously as they once treated front-row seating.
