Unique ValuesΒΆ

As you may know from powermail 1.x you can enforce that every value of a field should only exist once. This could be helpful if you want to start a competition with powermail and every email should only saved once.

plugin.tx_powermail.settings.setup.validation {
        unique {
                # Enable unique check for {email} - every email must be unique on the page where mails are stored
                email = 1

                # Enable a max limit of 3 times for the same entry for {event}
                event = 3
