A: Hello b25ce11cae994887b49edeff84032c18,

Thank you for your email and your question.

Notifications in TidyCal are sent automatically and periodically, which means that TidyCal will send the first notification at the time the booking is created to you and your booker, while the two email reminders will be sent to all based on your settings in the specific booking type.

There is no need for any other settings or services.

Have a great day and kind regards.
