How to reach attendees with EVA, with or without an event app

Your event has an app with the programme, speakers and venue map. You have prepared it to be useful, but before someone receives a notification they need to install it and grant the relevant permissions. Meanwhile, they still need their ticket and directions.

EVA can open communication before that step and maintain a conversation through WhatsApp, SMS or web chat. At some events it covers the tasks you would have used an app for. At others, it guides the attendee to an interface they do need. The choice depends on the experience you want to offer and the functions the event requires.

Start with what the attendee needs to do

The decision about EVA and an app starts with specific tasks. Receiving a ticket, finding an assigned transfer and exploring an interactive map are different experiences. Grouping them under “event information” hides that difference.

Take Luis at a corporate event: he needs to reach the venue, show his QR code, follow the programme and find his return coach. A conversation with the event details and his group information can resolve those enquiries. He does not necessarily need a dedicated app for that process.

Now consider an exhibition with several zones and an extensive session programme. Luis may want to browse a map, compare options visually and consult speaker profiles. A well-designed app can provide a useful interface for those tasks. EVA can answer questions or recommend a starting point, but that does not turn the conversation into an interactive map.

The number of features is not enough to make the decision. Review how someone arriving with a mobile in their hand and little time to understand your system will carry out each task.

EVA can be the first contact before any installation

By collecting phone numbers at registration and preparing the planned contact with attendees, you can begin with EVA. The first message introduces the AI assistant, identifies the event and explains what people can ask in that conversation.

EVA can deliver a ticket with its QR code, remind people of instructions and answer questions using the available information. The relevant access system validates the ticket at the door. That distinction helps organise the integration without attributing another platform’s function to the chat.

EVA: Hello, Luis. I’m the exhibition’s AI assistant. Here is your ticket with its QR code. You can ask me about access, times or planning your visit.

Luis: I’m arriving after lunch. Which entrance should I use?

EVA: The visitor entrance is the north gate. Badge collection stays open in the afternoon; you can show the QR code from this chat.

Luis has already received something useful and been able to clarify a question. The conversation does not depend on him first exploring every feature of the app. That first contact is particularly useful when the download has not yet happened.

Choose the channel around your audience too: WhatsApp, SMS or a chat embedded in the organiser’s website. Attendees will not necessarily want the same route. The website gives them another way to ask questions without adding an installation.

Recommend the app when it resolves a specific need

EVA can direct attendees to the app when a question needs its functions. The invitation makes more sense if it explains what they can do there and provides the relevant link.

Luis: I want to see where the lighting stands are and mark the ones that interest me.

EVA: You can do that in the exhibition app’s interactive map. It lets you find stands and save the ones you want to visit. Here is the download link.

This example depends on the chosen app having those functions and on you providing EVA with the information and link. It does not assume all apps offer the same map or that a direct link to every screen exists.

You can configure an EVA objective to encourage downloads. Build it around a useful task: consulting the map, saving a session selection or using a function specific to the app. Repeating the invitation in every reply, even when it has nothing to do with the question, adds friction.

You do not need to block the QR code until the app is installed if the system can already deliver it through EVA. Attendees can enter the event and discover the functions they want to use afterwards.

Avoid creating two different places to do the same thing

Combining EVA with an app means allocating tasks and keeping information consistent. If both send notifications, display tickets and answer questions using different data, the organising team has two systems to check and attendees have to decide which to trust.

The combination is worthwhile when each part contributes something specific. You could use EVA for first contact and conversation, and the app for the map or visual exploration of the programme. If the event does not need those additional functions, you may simply be duplicating the process.

Attendee task	Possible role for EVA	When to consider an app
Receive a ticket and check arrival details	QR delivery and instructions in the conversation	If other access requirements need that interface
Ask about an assigned transfer	A reply tailored to the group or booking, using provided data	If an operation needs managing that the chat does not cover
Find content by interest	A recommendation using the programme and available context	To explore an extensive agenda, compare or save sessions
Find their way around a complex venue	Answer directions and provide links	When an interactive map provides a necessary function
Receive important updates	Communications prepared by the organising team	If app notifications have a distinct, agreed role

The table guides the review, but it does not replace checking the actual products’ functions. An app does not meet every event requirement by default either.

If you use both, identify the source of the current programme and who changes the information when a session moves. Review the available integrations before assuming a change will appear everywhere automatically. Coordination needs to be part of the preparation.

Decide where to keep the main communication

Attendees need to understand the main channel. If you have opened a conversation in EVA, explain which updates they will receive there and why you are recommending the app. Avoid sending the same reminder through every route without a specific reason.

App notifications need installation and the relevant permissions. Attendees can control what they receive, as shown in iPhone notification settings. Making an app available does not mean the whole audience is available through it. Sending through EVA does not guarantee every person sees or answers the message either. Check how the process works with your attendees before relying on a single signal.

Prepare tests that include someone who has not installed the app: they receive the QR code, ask a question and need a function available only there. Then test what happens if they prefer to keep asking questions in the chat. You may discover an unnecessarily compulsory download or a reply that directs the attendee to an app without explaining why.

What to prepare before choosing the approach

Write down the tasks you expect attendees to carry out and the context each needs. Mark which can be resolved through conversation and which require another interaction. This list helps you discuss the project with a provider without starting with “we want an app” or “we want an assistant”.

With EVA, the information provided, integrations and configured functions determine what can be resolved. You can use the EVA communication plan to organise first contact and reminders once you have decided where each task happens.

For a simple corporate event, delivering the ticket and answering questions in a conversation may be enough. For an exhibition that needs a map, EVA can help with arrival and direct Luis to the app when he wants to explore the venue. The process works well when he understands what to do next and does not have to learn two systems to achieve the same thing.
