I would like to design a global email template (with header/footer and font/color settings) so all emails have the same design.
Right now we use "WP HTML Mail" to provide a custom email template for all system emails. Only MailPoet emails do not use that template.
Can you consider to
(a) Allow us to provide one/more global HTML templates that we can choose from when editing a new email (e.g. via an HTML file in the child-theme).
(b) Or integrate a toggle to enable the global "WP HTML Mail" templates
(This is the plugin I'm referring to: https://de.wordpress.org/plugins/wp-html-mail/)
