Feature Request: BCC / History

Hello,

I like to have two features which I find helpful to see if the plugin did work and to whom I send links already.

I like to have the ability to store a history of all email-addresses that have already received an invitation link.

I would appreaciate to have the opportunity to set a BCC address which would be used to receive a copy of all emails that will be send out.

Many thanks for considering.

Cheers
Yogie
