Alerts and order messages
What you get told (bell, email, WhatsApp) and what your customers get told at each step.
What your customers get
At every step — placed, payment received, confirmed, packed, shipped (with courier and tracking), delivered, cancelled, return requested / approved / refused / received, refund issued — the customer gets an email (if their account has one) and a WhatsApp message where an approved template exists and the trigger is switched on in Settings → Communication. Customers choose their channels under Your Account → Notification preferences.
What you get
Store settings → Notifications: new order, return request, failed payment, low stock (once a day per product), new question. Email goes to every admin of the shop. "Also WhatsApp me" sends to the shop's contact number — off unless you switch it on.
Where to see what was sent
Open any order → Messages sent at the bottom: every email and WhatsApp about it, with sent / failed and the reason.
