The plugin is sending BCC messages to the default WordPress email even though the recipients field is empty

I have checked “Send Only To Customer?” and left “Recipients” empty. The plugin is sending to the customer but also the default WordPress e-mail as BCC.

I’m using this plugin for a vacation message, so I don’t wan’t my inbox to be flooded with irrelevant vacation messages to me as BCC. Only the customers need it.

It should be a feature to select only customers and no one else.
