Institutions continue to craft messages for public feeds whilst their audiences make decisions, form opinions and share information in WhatsApp groups and Telegram channels that no institutional algorithm can reach. Being late to this shift is not a technical problem. It raises questions about how trust works when public visibility disappears and what remains are relationships, proximity and shared judgement.
This blog is not a tutorial on tools. It is a reflection on what changes when an institution decides to be present in these spaces, and what it needs to understand before attempting to do so.
Why institutional authority and persuasion work differently in closed messaging groups
In a public feed, institutional authority operates through recognisable signals: the logo, an official tone, the number of followers, and visual consistency. The reader knows they are consuming communication from an organisation and activates the corresponding filters, for better or for worse.
In a closed WhatsApp or Telegram group, those signals disappear or lose their weight. What circulates comes via people, not organisations. A message from an institution entering that space does not compete with other institutions: it competes with the trust that group members have in one another.
The Reuters Institute’s Digital News Report 2024, based on a survey of nearly 100,000 people across 47 countries, found that WhatsApp is used for news consumption by 21% of the global sample, with sustained growth, particularly outside Western Europe. It adds a more specific point: the content circulating on WhatsApp comes from close circles, which generates greater perceived trust. Paradoxically, this also means that critical defences are lower. People do not verify what someone they trust sends them with the same rigour.
For institutions, this has a direct implication: entering these spaces without understanding how relational authority works within them produces the opposite effect to that intended. A message that would sound credible in an official feed may be perceived in a private group as an intrusion, propaganda or noise.
What does the shift of audiences towards closed messaging platforms mean for public communication?
The shift is not uniform. It varies by geography, age group, topic and prior level of institutional trust. In contexts where trust in traditional media is historically low or where internet access is primarily via mobile devices, WhatsApp is not an alternative to news channels; it is the main channel. In Europe, the shift is more selective. Still, it is concentrated precisely in the groups that are hardest for institutions to reach: communities with lower trust in traditional media, activist networks, informal professional groups, and migrant communities.
What all these spaces have in common is that the institution cannot reach them directly without relational mediation. There is no way to “post” in a closed group to which one does not belong. There are only ways to be present through people who are already part of that group and who consider institutional information worth sharing.
How trust works in closed messaging groups and how this differs from standard institutional channels
Trust in public institutional channels is built through coherence, transparency and consistency over time. It is a trust earned and verified in public.
Trust in closed messaging works differently. It is not about trusting the institution, but about trusting the person who introduces the information into the group. That person acts as an intermediary and, by sharing something, is putting their own credibility on the line. If the institutional content turns out to be unhelpful, confusing, or perceived as self-serving, the damage falls not only on the institution but also on the person who shared it.
This radically changes how institutional communication intended for circulation in such spaces should be designed.
Why institutional content is accepted or rejected in private groups
Content shared in closed groups is subject to different criteria from those applied to content published on official channels. In an institutional feed, the main criteria are the source’s relevance and credibility. In a private group, the main criteria are the usefulness to the members of that specific group and the intermediary’s comfort in sharing it.
A well-written technical document may be highly valuable on an official channel yet completely unusable in a WhatsApp group because nobody is going to read eight pages in that context. A short thread with actionable information on something the group needs to resolve today can circulate easily because the person sharing it doesn’t need to explain why: it speaks for itself.
The question that institutions rarely ask themselves is: Is this content useful to the recipient, or is it useful to the sender? Most institutional communication is designed with the latter in mind.
