/**
 * Arguments used for sending notification emails.
 *
 * <p>Notification emails are sent by out by {@link OutgoingEmail} and it's subclasses, so called
 * senders. To construct an email the sender class needs to get various other classes injected.
 * Instead of injecting these classes into the sender classes directly, they only get {@code
 * EmailArguments} injected and {@code EmailArguments} provides them all dependencies that they
 * need.
 *
 * <p>This class is public because plugins need access to it for sending emails.
