Knowledge base > Your domains > Adding MX Record on Google Domains
The is minor deviation in adding MX record, when your domain registrar is Google Domains.
Google Domains merge Priority with Value into a single textbox.
And all MX records must be entered at once, else it can result in a bug with google domains, where only one MX entry is shown.
This is how the MX record should be entered in Google Domains, where 0 is the priority number used.
