Using a custom email template with Email Plugin

Hi there!
I am still in the process of learning all the good things that come with Grav.
Currently I’d like to replace my /email/templates/base.html.twig file with a custom designed email template.
I have tried adding a copy to my theme under /templates/email/base.html.twig and also tried /templates/partials/email/base.html.twig
I’ve had no luck with either.
This is likely under my nose somewhere, but I haven’t had any luck with overriding the default base.html.twig template. I also don’t see an option for defining a specific template in the form.md file.
Thank you for your help!

@rnjr It seems to be working OK in my installation:

  • Copied folder ‘/user/plugins/email/templates/email’ to folder ‘/user/themes/mytheme/templates/’
  • Changed style in ‘/user/themes/mytheme/templates/email/base.html.twig’ to:
    h1, h2, h3 {
        ...
        color: red;
    }
    
  • Send email using $ bin/plugin email test-email -t <my email address>
  • Received an email with a header in red…

Which theme are you using?
