You have a client coming in by 9:00 am. It’s currently 8:45 am, everything is all prepped and ready to go. 9:00 am hits, then 9:15 am, 9:30 am — now it’s 10:00 am and still your client hasn’t shown up.
You contact the client about their appointment, only to get hit with a typical no-show response like,
While these no-shows might be innocent, they can be a significant loss for your business, affecting your bottom line. According to recent reports, the average no-show rate is 10-15%. This means if your business earns €300,000, you will incur a revenue loss of €30,000—€45,000 yearly.
Luckily, you can mitigate your no-show rates by sending reminder messages on WhatsApp. In this blog, we’ll explore the benefits, templates to use, and how to set it up.
The primary reason for sending reminder messages is to get them read by the target recipient. You could opt for emails & SMS, but the open rate is barely 20%. However, with WhatsApp, this goes up to a 98% open rate, making it an excellent platform to remind your customers about upcoming appointments, events, and deadlines.
Also, combining the reminders with consistent WhatsApp follow-up messages before the actual date ensures your business is at the forefront of the customer’s mind.
Since WhatsApp provides a more friendly communication approach, customers are more likely to respond positively to your reminders. With this, you can tailor your message to each customer based on the event date, their needs, type of service, etc.
Here's an example of what a WhatsApp reminder looks like.

You can set up a WhatsApp reminder by following these steps:
Note: Your template has to have been pre-approved by WhatsApp before adding it to your broadcast. This can be easily done via Trengo.
Once this is activated, WhatsApp will send out your reminder to the designated recipient(s) at the scheduled time.

If you run a business where several client book appointments with you, sending out reminders manually can be a hassling task. In this case, automating the entire process will take the load off you and your team.
To make this work, you’ll first need to create a chatbot in Trengo that will trigger the reminder setup process.
