Answer 1

If you want to send the gsp page as email body then you can send it like:

def mailService

def serviceMethod(EmailModel mailObj) {
...
    mailService.sendMail {
        to email
        subject "subject"
        body(view: "/_template", model: [mailObj: mailObj])
    }
...
}

EDIT...................................................................................

Just inject PageRenderer groovyPageRenderer globally, like

import grails.gsp.PageRenderer
class TestService {
    PageRenderer groovyPageRenderer

    def getText() {
        String s = groovyPageRenderer.render(template: "../first/temp", model: [name: 'user1690588'])
        println "Content = ${s}"
    }
}
