A “www” version of their domain must be created. Create this “www” version following the steps outlined here.
Once the “www” and non-www versions of the domain are submitted, copy the DNS value listed.
Go to the Domain Host / DNS Provider and follow your provider’s instructions on adding a CNAME Record with the value copied from Tovuti. (The following screenshots are from GoDaddy, as this is a widely used DNS Provider)
Either edit the existing “www” domain to match the value copied from Tovuti, or add a new version in the DNS Records.
After adding the “www” CNAME Record, forwarding options for Root Domain are available. Go to the Forwarding Section and click Add Forwarding.
Enter the “www” version of the domain.
Select Permanent (301) as the Forwarding Type.
