i would suggest a features you already have but need it to be with more options for most of the email service provider.
these days we are changing always from email service provider to another as per clients request and as per partnership with any provider.
you already add an option to add Google gsuite mx records with one click, we need you to add an option for Microsoft Office 365 and ZOHO.
this will make our tasks very easy to switch between email service provider for mx records.
also if you can add one click delete for mx records.
i hop that you can work on that.
