6.5 Tips & troubleshooting

• "Messages don't go out": check the channel (Email/SMS) is on, the customer has that channel's contact, and there's still allowance or credits (6.3). Each appointment's notification history (3.3) shows the status: Sent / Failed / Skipped (with the reason).
• SMS "Skipped": no balance, or the SMS reminder was skipped because the appointment was already confirmed by send time.
• Email goes to spam: ask customers to add the sender to contacts; the content is sent in a branded HTML template.
• No keys configured (test environment): sends are only logged as "Failed" without sending — normal without the Email/SMS keys.

💡 Scenario: you want to cut no-shows. Turn on the Reminder by email 24 h before and, optionally, by SMS 3 h before; include the /c/{token} link so the customer confirms with one tap.
