How to change common styles for redmine email messages?

Question

I need to make some styles available for every html email message in my custom redmine plugin. So I should do something with mailer layout https://github.com/redmine/redmine/blob/master/app/views/layouts/mailer.html.erb

As this file doesn't contain any hook ( http://www.redmine.org/projects/redmine/wiki/Plugin_Tutorial#Using-hooks ) only thing I can imagine to do it in this case is to override the layout in the plugin.

Is there any way to avoid overriding?

There is a gem deface which can help you.

I changed some parts of the view on the fly using deface. Please see this commit.
