In addition to sending an e-mail, you can also send a text message to your customers as a reminder of the planned appointment.
Where do I set the SMS reminder?
Go to Settings > Calendar settings > Calendar
In the settings you can determine how many hours in advance the SMS will be sent to your customers.
What does an SMS reminder look like?
Go to Settings > Company > Communication
Here you can manage and adjust all automatic messages sent to your customers. For instance:
Where do I buy SMS credits?
Go to Settings > Sms Credits > Buy Sms Credits
The cost per credit depends on the amount of credits that you purchase. Every SMS message is always 1 credit. A long SMS sometimes costs several credits. The purchased credits never expire.
An invoice is created automatically when buying credits. The credits are credited immediately.
Please be aware: to be able to purchase SMS credits you must first have a subscription.
