I am in the process of Transferring the website Hosting with Webflow to the New Domain Registar.
Pointing the A records where it belongs.
How do I make sure the Email Service will not be messed up without any errors?
It would be helpful to be able to see the domain records before telling you what may or may not need changing. It always depends on your specific setup.
In general, you don’t want to modify the values for the MX records or a mail host.
Share your domain name or your domain name records for additional assistance.
