Encapsulating a service call within a domain object object

Question

Is this a valid object design? I have a domain object where I insert the service and call the verification method to update the state of the object, and if everything goes well, send a confirmation message. The code looks like this:

class Foo {
  String bar
  Service emailService


  public boolean verify() {
    bar = "foo"
        if(this.save()) {
            emailService.sendConfirmation()
        }
  }
}

Foo.get(1).verify()

Is it allowed to call the email service in this case? Is there a design template that I can use for such a situation.

Thank. - Ken
