Sometimes, we as the users add a booking appointment or change a booking in the calendar but do not want to send any notification. For this aim, there should be a choice in the admin/user calendar booking page and when selected no notification should be sent to the client. For example, I may want to change a 20-min service time to 15 minute and the booking start time will not change and I do not want to send any notification to the client.
It's crucial for providers to have the option of whether to inform their clients or not when they make changes to a service, especially since there can be multiple providers offering the same service. Sometimes, specific provider changes are not of concern to the customer. For instance, if a driving training school replaces a training car due to maintenance, but all the cars are identical, the change might not be significant to the student.
It would be great to have the option to not send notifications for certain changes or to certain clients. Not everybody wants the emails.
