In current digital era, companies like rediffmail pro one of the poorest service provider for bellow following reason:
No good interface
Not compatible with other domain owners
No backhand support team after COVID 19, no one receive your call or give you any support.
Support center is very rude and wont give you time to resolve your problem.
No moneyback policy like other email business suite provider.
Not integrated with other application.( Current scenario, email suite must integrate with external applications like, Appointment Scheduler, CRM, Project Management Software, Video Conference etc.
There is no use of such email suite, even they show less in price but totally useless in current era. Its better to configure your business with gsuite or Microsoft 365, where you will get all application else, rediffmail will cost you late 10 times higher than others when you use other digital applications.
I never recommend to go with rediffmail totally wastage of money and Poor Support Staff.
