Automatically send emails to the customers via Facebook Messenger, WhatsApp, and SMS

when I select all the orders and set them to 'Sammelbox' createtetd status, it should automatically send emails to the customers via Facebook Messenger, WhatsApp, and SMS. A reminder should be sent via Messenger and email after 2 days. 6. When an order is paid from 'Sammelbox,' it should change to 'bezahlt' status and move to a page for paid orders that are ready for shipment.How?
