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

Oatly is not oat milk. Oatly is a statement.

Oatly does not sell a product. Oatly sells an attitude.
And this is not marketing speak, but a strategic decision.

While many food brands rely on Health Claims, and soft-pedalled promises of sustainability, Oatly does something completely different:
The brand speaks. And in the way that brands actually should not speak.

This is particularly evident in social media marketing. Here you can see how Brand Strategy becomes a living language. Humour is not a nice extra, but brand-defining element. Oatly uses language as a tool to reduce distance, generate 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 disruptive factor.

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. That 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 social media marketing. Oatly does not communicate about the community, but with her. Comments are allowed to contradict. Campaigns can be offensive. Posts can be absurd.

The result: a brand with clear edge, which not everyone likes – but which remains relevant for precisely this reason.

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

Oatly's Tone of Voice seems spontaneous. But it is not.
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 Signal transmitter.
He says: We don't take ourselves more seriously than the cause. 
And that is precisely what makes the brand credible.

In the social media context, this language ensures high Shareability, strong community loyalty and recognisability – even without a logo.

Humour as a brand tool – not as a gag

Many brands „do humour“. Oatly is humorous.
That is 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 creates irritation.
And irritation generates 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 seen, 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 packaging, OOH or website:

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

This also means:
No trending hashtags without meaning.
No copy-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.

This is a key realisation for sustainable brands:
Consistency beats volume.
And attitude beats reach.

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

Oatly ensures this in a very targeted way, what – is said through language, tone of voice and the courage to be uncomfortable.
