Can I connect to my Email Hosting account using a CNAME?
Yes, you can connect to your Email Hosting account using a CNAME. To do this, please use the CNAME webhost.dynadot.com
For your email to work, please include the MX record webhost.dynadot.com
Please be aware it may take anywhere from 20 minutes to 24 hours for your DNS changes to propagate.
The benefit to using a CNAME vs. an A Record is that if the Email Hosting IP address is ever changed, you will not need to adjust your settings. You can also choose to simply use the "Dynadot Hosting" settings.
