Can't use CNAME for ZOHO Sites

Can't use CNAME for ZOHO Sites

I am aware of the service disruptions for zoho sites.  I received the email for changing the CNAME records for our site.  We use 1and1 as our domain host, for our email, and online storage.  If we change the CNAME records with 1and1 we lose our email accessibility.  We were previously using the A Records with the IP address with no issues.  How can we setup our website to use the A records so we don't lose our email with 1and1?

Please reply quickly as we currently have not website up for our clients to go to.
