Custom Buttons in email/notifications to update board

I am looking to have the ability to use the gmail or notification function to be able to have buttons in the email that would be able to update the board.
IE, when I set an appointment to someone who is not in Monday, they have the ability to click a button in the email to confirm or reschedule the appointment. Then update the status column to the button they have pressed in the email.
Similar to Calendly or a google calender invite
