Yes. Settings → Notifications has a switch for each email we send — disruption alerts, the daily disruption digest and the daily shipment report. Turning one off stops it immediately. Transactional mail (login codes, receipts, a failed payment, replies to your support tickets) still reaches you.
The email body shows the first 8 columns; everything after that is tagged "attachment only" and is still in the attached spreadsheet. Drag a column above the eighth position to bring it into the email itself.
Yes — Settings → Notifications → Daily shipment report → How often offers every day, weekdays only, or once a week on a day you choose. You can also narrow it to only delayed shipments, or only those arriving in the next 7 days.
Yes. Per customer you can switch on alerts for departure, arrival, ETA change and free days ending. Each event is independent, and every email carries a one-click unsubscribe so the customer stays in control.
Alerts are switched on for them but there is no contact email on file, so nothing can actually be sent. It is shown in amber because it looks configured and delivers nothing. Add a contact email to the customer and the alerts start working.
You can, from the dashboard — but ask them first. The unsubscribe link switches off all four events at once and it was their decision. Re-enabling without asking is how an account ends up marked as spam, which hurts delivery for every email you send.
Nothing is sent on a quiet day. The digest only goes out when there is something active to report, because an empty summary trains you to ignore the real ones.
Settings → Notifications → Daily shipment report has a "Send me a test report now" button. It sends immediately using your current columns, scope and attachment format.
