To make things nice and clear, as some of the GoDaddy help articles are dead wrong:
You just need to paste the two records from the server settings into your Route 53 control panel as a new record.
The possible deception here is the the GD email panel will tell you you’re wrong, but not what is right so you can make it right. Further, their help article tells you do look for the proper MX record settings under the Domains manager, where you’ll not find them.
Finally, AWS is a tad confusing since they’ll only let you enter a single apex domain MX entry. You can’t have two as GD wants and some other zone managers allow, hence the need to double them up.
Hope this helps others! 🙂
