After installing the plugin I get

*** failed to install emails: Getting unknown property: craft\ckeditor\Plugin::ckeConfigs

but Emails is installed. When I click on "New Email" I get

Calling unknown method: craft\ckeditor\Plugin::ckeConfigs() in "emails/_includes/config-form" at line 69

• Emails version: 3.0.1
• Craft version: 5.9.21

Hi @SanboKyo there was a fair amount of changes to do after the CkEditor 5 update, which I've finally found time to do.
Released 4.0.0 just now.

Note that you will need to resave all your emails configs, ckeditor external configs have been removed in version 5 and each email will define its own config separately
