Benefits of using WhatsApp for auto confirmations and reminders
High open rates - WhatsApp messages have very high open rates, often 90% or more. This means your confirmations and reminders are highly likely to be seen by the recipients.
Instant notifications - WhatsApp messages trigger instant notifications on the recipient's phone, so they are aware of the message right away. This allows them to take action quickly based on the confirmation or reminder.
Read receipts - WhatsApp has read receipts, so you know if your message has been read by the recipient. This allows you to potentially follow up if a critical confirmation or reminder goes unread. (This feature will be available in the next phase)
Cost-effective - Using WhatsApp for notifications is very cost-effective compared to SMS. WhatsApp messages are free, so it reduces operational costs.
Works on all devices - WhatsApp works on all major mobile platforms as well as desktops. So your messages will reach the recipients regardless of what device they use.
How to enable WhatsApp feature
1. Enable WhatsApp Notification. Before setting up the registration forms, navigate to Event Settings, and you can enable the WhatsApp Notification under the Event Delivering Methods.
You can also fill in the event information such as event banner, event locations (for in-person events), event date and time etc under the same setting page.

2. Create a Registration Form. Navigate to the Registration Form on the left side menu, and set up the registration form(s) for public registration.
3. Confirm the event details on the automated templates. As the templates are pre-approved by WhatsApp/Meta, the content cannot be edited. However, the message is personalised with attendee name on each message.
The WhatsApp templates will be different per event format: In-person, Hybrid, and Virtual event. The template for your event can be viewed under the WhatsApp page on the portal as shown in the screenshot below.
There are 3 templates for each event format:
- Confirmation after the registration form is submitted
- 24 Hour Reminder before the event start date
- 1 Hour Reminder before the event start date

Important Reminder: WhatsApp Delivery Rate
Please note that we cannot guarantee a 100% delivery rate for WhatsApp messages.
Why?
EventX connects directly to Meta’s official WhatsApp Business API. Meta has strict security and anti-spam policies in place to protect users. As a result, messages may not be delivered if the recipient has not previously opted in or has restricted messages from unknown business numbers.
Our Commitment to Transparency
EventX provides a complete delivery log for every campaign. For any undelivered messages, we will automatically rebate the corresponding WhatsApp quota. Organizers can use this data to follow up with attendees through other channels.
