Blocking / black listing customers

Blocking / black listing customers


We have a situation, we observed that certain customers are blocking multiple appointments with our advsiors but not showing up. Some of these are repeat offenders. This leads to those service hours getting blocked and not available for genuine customers. Also leads to reduced advisor productivity.

We would like to block or blacklist such customers based on their email id. Any suggestions, how we can achieve this in Zoho bookings?
