Heineken targets voice note overload with WhatsApp bot

Voice notes have become a dominant form of digital communication, but growing evidence suggests they are also contributing to distraction and fewer in-person interactions.

Heineken has launched a WhatsApp-based technology pilot designed to encourage people to replace extended voice note exchanges with face-to-face meetings, offering a free beer as an incentive.

Developed with creative agencies LePub Milan and LePub São Paulo, the pilot has launched in Brazil, a market where Meta data shows users send four times as many voice notes as any other country. The initiative targets WhatsApp voice notes lasting three minutes or longer, allowing recipients to exchange them for a beer voucher and suggestions for local bars.

Voice notes and time spent online

Global research conducted among 14,000 respondents found that the average person spends almost 150 hours a year sending and receiving voice notes. The findings indicate that the format is not only time-consuming but also increasingly one-sided.

More than half of respondents, 52 percent, believe voice notes are replacing in real life interactions, rising to 60 percent among Gen Z. Nearly half, 49 percent, say they have spent entire evenings exchanging voice notes instead of meeting in person, despite 54 percent reporting that their most fulfilling conversations happen face-to-face.

Rising volume and declining attention

Data from Statista shows that 9.4 billion WhatsApp voice notes are now sent every day, equivalent to around 3.4 trillion over a year. Compared with 2024, the frequency of voice notes has increased by 7 percent, while their average length has grown by 8 percent.

Stacy Jo Dixon, Social Media and Society Expert at Statista: “Our data suggests that voice notes are not just growing in frequency but also length. With nearly 9.5 billion voice notes sent daily on WhatsApp alone, it’s evident that voice messaging is reshaping the way we communicate across the globe and taking on a more prominent role alongside traditional in-person interactions.”

Engagement with voice notes appears limited. More than half of users, 55 percent, admit they often forget to listen to them, while 88 percent say they forget what was said even after listening.

Turning digital habits into real-world meetings

Heineken positions the pilot as a response to these patterns, aiming to redirect digital behaviour towards socialising in person.

Nabil Nasser, Global Head of Heineken: “Just like we all know meetings that could have been an email, we’re now seeing voice notes that could have been a Heineken. Voice notes can feel more personal than reading a message, but what our research shows is that we need to make sure they don’t turn into extended monologues.”

He added: “At Heineken, we want to make it easier for people to share moments of socialisation in real life. That’s why we have launched the Could have been a Heineken WhatsApp bot, incentivising people to swap long voice notes for an in-person catch up.”

Campaign rollout and mechanics

The campaign launches in Brazil with out-of-home placements and social activations designed to anchor the idea in local culture. Additional markets are planned in the coming months.

To redeem the offer, WhatsApp users aged over 18 forward a received voice note longer than three minutes to a private, encrypted bot. In return, they receive a message stating it could have been a Heineken, along with a voucher for a free beer and recommendations for nearby bars to meet in person.

Bruno Bertelli, Global CEO LePub and CCO LePub Worldwide: “With this idea, we set out to turn a familiar digital habit into a real-world moment of connection. By flipping everyday behaviour, we’re using technology as a trigger that brings people back together and encourages face-to-face conversation.”
