We have changed to a new website host/server and have consequently 2 issues: 

a) We have stopped receiving emails in current email address assigned under that initial domain name.; and 

b) Our new website content says it has launched but has not actually launched (IE the old content is still displaying when we type in the website URL)..

*We are struggling to follow the 'HELP' sections of Zoho so please can you talk us through this.

Please how do we remedy this? IE 

a) begin receiving emails again, and

b) have the new content of our website visible for the public?
