Editable mail templates

[Poseidon281]

For example using the already installed Monaco Editor. I would like it if the mail templates can be edited.

Would like to mention that I've had Google flag my emails as spam on occasion, this is the only service that I've had that happen so far, which is a little frustrating but ... not much that can be done unless I can make the emails look better so that I can pass the Google spam filter far more effectively.
