If you have enabled the SMS module in YoungCRM, you can send text messages together with your event emails.
When you have enabled an email to your event, you can also enable SMS to the event. After enabling an SMS, you must enter a sender name (14 characters max.) and write the text for the SMS. It works just like when creating an SMS.
When enabling SMS, both SMS and email will be sent out to the people who have signed up for the event.
