It is possible to see when an appointment has been created in the Skedify web application . You do not need to look into you mailbox to find out when the confirmation e-mail has been sent. 
How? just follow the next steps:

1. Navigate to the Calendar view of Skedify and click on appointment details

2. In the pane opening on the right side on the screen you can find technical information giving you the possibility to consult when an appointment has been created and/or updated

This also works for external calendars which have been connected to your account, the view is a bit different but if you click on an appointment (1), you will find the same information (2)
