ExeltIQ sends emails and web-push notifications around key events — bookings, waitlist changes, package assignments and purchases, cancellations and shop purchases. What gets emailed depends on your notification settings.
Yes. Under SMS → Automated you can set up session reminders (with email, push or SMS, a chosen number of hours before, and a custom message), appointment reminders, birthday messages and package-expiry reminders.
Usually the relevant email notification is turned off in your settings, the member has no email on file, that event type isn't emailed, or the email couldn't be delivered.
