Using SMS reminders

SMS (text messages) are an excellent way to send your invitees a confirmation or reminder before the booking and can help keep your invitees engaged, reducing no-shows.  

In this guide you'll learn how to setup SMS notifications on your booking page that send to your invitee. 

Step 1: Purchase SMS credits on your account

SMS credits can be purchased on any of your booking page editor by scrolling to the Notifications section and clicking "Buy credits".

Purchasing 200 credits or more will qualify for volume discount. Use the slider on the SMS purchase page to select how many SMS you'll need.

When you buy SMS credits, those can then be used on all your booking pages and even your teammates' pages.

Step 2: Add a Phone question to your Booking Form

Koalendar needs your invitee’s phone number to send SMS messages. This can happen in one of two ways:

• If your meeting location is set to Phone Call, the invitee will be asked for their phone number automatically.

  

• OR, you can add a custom question to your booking form with the type set to "Phone Number".

  

As long as Koalendar has a valid number, reminders will be sent according to your settings.

SMS work in all countries. The phone question automatically detects your invitee's location to pre-fill the international field accordingly.

💡 Best Practices

• Use SMS reminders in addition to email to increase attendance
• Keep messages short to avoid using multiple text credits

• Example reminder:

  "Reminder: You’re booked for {BOOKING_PAGE_TITLE} on {DATE}."
