Oatly: How humour and tone of voice became the strongest brand strategy

Oatly is not oat milk. Oatly is a statement.

Oatly doesn’t sell a product. Oatly sells a way of thinking.
And that’s not just marketing jargon, but a strategic decision.

Whilst many food brands rely on health claims, an aesthetic of perfection and watered-down sustainability promises, Oatly does something completely different:
the brand speaks. And it does so in a way that brands are not actually supposed to speak.

This is particularly evident in social media marketing. Here, we see how brand strategy is brought to life through language. Humour is not just a nice extra here, but a brand-defining element. Oatly uses language as a tool to break down barriers, capture attention and create cultural relevance.

Or to put it another way: Oatly doesn't want to please. Oatly wants to resonate.

Brand Strategy: The conscious decision in favour of the Challenger role

Every strong brand voice begins with a clear strategic stance. At Oatly, this is: We are the disruptors.

The brand strategy is based on a few basic assumptions that are implemented extremely consistently:

• The market is full of interchangeable messages
• People have had enough of slick brands
• Sustainability needs honesty, not a glossy façade

Oatly deliberately positions itself as a challenger brand. This means:

• Do not adapt, but question.
• Not to explain, but to comment.
• Don't try to convince, but allow discussion.

This strategy is directly reflected in the company’s social media marketing. Oatly does not communicate about the community, but with it. Comments are allowed to be critical. Campaigns are allowed to be controversial. Posts are allowed to be absurd.

The result: a brand with a distinct edge that doesn’t appeal to everyone – but remains relevant precisely for that reason.

Tone of Voice: Cheeky, self-deprecating, human – and maximally conscious

Oatly’s tone of voice comes across as spontaneous. But it isn’t.
It is highly strategic.

The language follows clear principles:

• Everyday language instead of marketing language
• Irony instead of instruction
• Personality instead of perfection

Oatly writes the way people think. Disorganised. Honest. Sometimes slightly annoyed. Sometimes overly reflective. Often with a humorous twist that breaks expectations.

Important: Humour is never just for entertainment. It is a signal.
It says: We don’t take ourselves more seriously than the cause.
And that is precisely what makes the brand credible.

In the context of social media, this language ensures high shareability, strong community engagement and brand recognition – even without a logo.

Humour as a brand tool – not as a gag

Many brands „use humour“. Oatly is humorous .
That’s a big difference.

Humour at Oatly fulfils several functions at the same time:

• It lowers the entry barrier to complex topics such as sustainability
• It makes attitude accessible without appearing moralistic
• It creates emotional closeness

The humour is often deliberately unwieldy. Texts are long. Statements seem almost too honest. Some messages read like internal thoughts made public by –.

That causes irritation.
And irritation attracts attention.

Humour is therefore not an end in itself, but part of the communicative brand architecture. It helps to ensure that Oatly is not only noticed, but also remembered.

Social media as an extension of the brand identity

Oatly does not use social media as a sales channel, but as a cultural platform.
Every post follows the same logic as the packaging, OOH or website:

• same language
• same attitude
• The same desire to break the rules

This also means:
No meaningless trend hashtags.
No copy-and-paste CTAs.
No empty sustainability claims.

Instead, content is created that feels like commentary on the zeitgeist. Social media becomes a stage for brand personality – not a discount wall.

For sustainable brands, this is a key insight:
Consistency trumps volume.
And stance trumps reach.

„Your brand is what people say about you when you're not in the room.“

Oatly takes great care to ensure what is said – through language, tone of voice and the courage to be uncomfortable.
