How many contacts from the last trade fair did you actually follow up on – and how many simply faded away? Between business cards, lead forms and CRM imports, there is often too little time for genuine dialogue. Yet it is precisely the personal conversation at the trade fair that is the perfect starting point for a strong customer relationship.
And this is exactly where WhatsApp comes in.
As a trade fair exhibitor, you don’t just want to stand out – you want to create lasting connections. Visitors should not only remember your stand, but also you as a contact person. With WhatsApp, you can achieve exactly that: personally, directly and without detours. Whether it’s spontaneous queries after the conversation, follow-ups in the evening or targeted campaigns after the trade fair – you can stay in close contact via the messenger.
WhatsApp is familiar, fast and uncomplicated – both for your leads and for your team. And with the right structure, communication can even be automated or linked to your CRM.
In this article, I’ll show you how to use WhatsApp effectively at trade fairs – from addressing visitors at your stand to systematic follow-up. You’ll learn which best practices really work, how to work in compliance with data protection regulations and how to achieve a big impact with small measures.
Trade fairs thrive on personal conversations, spontaneous encounters and genuine contacts. But it is precisely these contacts that often tend to fizzle out as soon as the trade fair is over. The reason? Between analogue business cards, handwritten lead sheets and overloaded CRM systems, the direct line to potential customers is quickly lost.
WhatsApp solves this problem in an elegant way. Not only is the messenger fast and easy to use, it is also the preferred communication channel for many people in their everyday lives. For visitors, this means they don’t have to take notes, install an app or wait for emails. A scan of the QR code, a short message – and the contact is established.
For you as an exhibitor, WhatsApp is more than just a digital replacement for brochures or contact forms. It is a tool that creates proximity, facilitates follow-up and allows you to accompany leads in a structured and personalised manner. Immediately after the conversation, you can send a message, share product information or arrange follow-up appointments – all in real time, without media discontinuity.
WhatsApp becomes particularly exciting when you combine it with automation and professional templates. This ensures that there are no gaps in the process and that every contact is followed up on after the trade fair.
In short, WhatsApp bridges the gap between the analogue trade fair stand and the digital customer relationship – quickly, directly and personally.
WhatsApp brings your trade fair presence into the 21st century. Instead of just collecting contacts, you can start real conversations – quickly, easily and right where your visitors are already active. Here are five practical use cases that you can implement right away:
Instead of exchanging business cards or laboriously filling out contact forms, visitors simply scan a QR code at your stand – and end up directly in a WhatsApp chat with your team. You can automate the initial contact, for example with a welcome message thanking them for visiting or offering further information. This immediately creates a personal contact that won’t be lost.
Instead of getting in touch days later, you can send a short message on the same day: “Thank you very much for visiting our stand today. Here is the link to the product demo again – please get in touch if you have any questions.” The advantage: the contact is still fresh, you remain present and the conversation thread is not broken.
Is there a live demo or presentation coming up at your stand? You can use WhatsApp to send a quick reminder to invited guests or spontaneously activate interested parties. Example: “Our live demonstration on [topic] will start in 15 minutes at our stand – feel free to drop by!”
Printed material often ends up in a bag and is never looked at again. With WhatsApp, you can send only what is really interesting – be it a PDF, a video or a link to the website. This saves paper, is more sustainable and sticks in the memory better.
With the WhatsApp Business API, you can automate targeted follow-ups after the trade fair: for example, a thank-you message, a feedback link or a special offer only for trade fair contacts. It is important that you only write to people who have actively agreed to this – via an opt-in process that you can set up directly at your stand.
These use cases show that WhatsApp is not just a communication channel, but an effective tool for lead nurturing – from initial contact to successful closure.
As practical as WhatsApp is, it is essential to handle contact data in a legally compliant manner, especially in the context of trade fairs. This is because you are processing personal information: names, telephone numbers, conversation content, interests. These are subject to the General Data Protection Regulation (GDPR) – and this also applies if you are simply “just sending a message”.
The widely used WhatsApp Business app may seem convenient at first glance, but it is not suitable for professional use. It accesses the smartphone’s address book and may transfer contact details to Meta without notice – even from people who have never consented to this. This means that its use in a business context is not permitted under data protection law.
The solution is the WhatsApp Business API. It enables you to use the app professionally and in compliance with the GDPR – without accessing the address book, with centralised access for your team and hosting options within Europe. You use a certified provider (BSP) who provides you with a platform through which you can send messages, set up automations and document consents.
Particularly important at trade fairs: you need an active opt-in from visitors before you can send them messages. You can implement this directly at your stand – e.g. via a QR code that leads to an opt-in page, or via a short form with consent to be contacted via WhatsApp.
Memacon is happy to help you implement this setup in a legally compliant and practical manner – including the appropriate templates, technology partners and texts for your trade fair campaign.
This ensures that you not only communicate efficiently, but also remain on the safe side legally.

If you want to be visible as an exhibitor, you need more than just a nice stand. It’s about real connections, conversations that stick in people’s minds – and ensuring that contact doesn’t end as soon as the trade fair is over. This is where WhatsApp really comes into its own.
The messenger is fast, personal and familiar – exactly what trade fair visitors want when they get in touch with you. Whether it’s an initial exchange at the stand, a follow-up in the evening or targeted follow-up actions: with WhatsApp, you remain present without being intrusive. You can deliver relevant information in real time, build trust and develop leads in a targeted manner – without media discontinuity and without friction losses.
The prerequisite for this is a data protection-compliant and professional implementation via the WhatsApp Business API. With clear processes, good templates and the right preparation, WhatsApp becomes a real lever for your trade fair success – regardless of whether you are a start-up, medium-sized company or corporation.
Most leads fizzle out because no one follows up. You can do better – with a channel that your target group already uses. WhatsApp connects the exhibition stand and follow-up directly. And that’s exactly what makes the difference.

WhatsApp can be used effectively at trade fairs when communication takes place via the official WhatsApp Business API. This allows you to contact interested parties in compliance with data protection regulations, provide information and structure follow-ups without resorting to private devices or group chats. Memacon® supports trade fair exhibitors in selecting a suitable API-enabled SaaS platform and implements a scalable communication solution for scheduling appointments, follow-up actions and sending information material.
API-based functions are particularly suitable for trade fair exhibitors, as they can be used to send individual messages to contacts and automate follow-up processes. These include approved message templates for follow-ups, system-based segmentation of trade fair contacts and structured processing of leads. Memacon® designs these functions to integrate seamlessly into the trade fair and sales process.
There are various SaaS solutions from official WhatsApp Business API providers that are suitable for use at trade fairs. These enable centralised contact management, structured individual communication and automated messages. Memacon® provides manufacturer-neutral advice on selecting a suitable platform and handles integration into existing systems and adaptation to the respective trade fair appearance.
The WhatsApp Business API provides functions that enable multiple employees to work in parallel, send messages automatically and document communication processes. In addition, trade fair contacts can be categorised by the system and targeted for further communication. Memacon® ensures that these functions are not used in isolation, but are part of a clearly defined lead and follow-up process.
Professional setup is not carried out directly in WhatsApp, but via a connected WhatsApp Business API platform. Memacon® supports trade fair exhibitors from the conception of opt-in registration at the stand via QR codes or tablets to the technical setup and training of stand personnel. This ensures that all processes are GDPR-compliant and fit the respective trade fair objectives.
What alternatives to the WhatsApp Business app are suitable for trade fair exhibitors in Germany?
Leads can be captured directly at the trade fair via the WhatsApp Business API, for example by scanning a QR code or initiating a chat. After a valid opt-in, the contacts can be automatically transferred to structured follow-up processes. Memacon® develops these processes in such a way that leads can be qualified, documented and processed promptly.
Memacon® supports trade fair exhibitors throughout the entire communication process, from strategic planning and technical implementation to operational support. Content and messages can be targeted before, during and after the trade fair, tailored to target groups, interests and trade fair objectives, without generating uncontrolled mass communication.
Group chats are not used for trade fair contacts. Instead, individual communication takes place via the WhatsApp Business API, based on system-side segmentations within the connected software. Memacon® sets up these structures so that interested parties can be contacted in a targeted manner with relevant information, documents or appointment suggestions.
The processing of visitor data at trade fairs is subject to strict data protection requirements. Legally compliant use of WhatsApp is only possible via the WhatsApp Business API if opt-in, documentation, hosting and data processing are implemented correctly. Memacon® ensures that these requirements are met and that trade fair communication is carried out in a data protection-compliant and professional manner.
