Access the message menu and create a new SMS from there.
On the preview screen, you can select the way you want to send this SMS.
It can be an automatic SMS (which will be sent at different times for each user, birthday SMS, order confirmation, reminders...) or a standard SMS sent immediately or at a scheduled time in the future.
You can include personal information in your SMS so each user will receive its own personalized SMS.
You can also use the filters to refine your receiver selections.
If you are using a gateway which supports MMS you can send MMS from your website
