I suggest Logos screen its Daily Deal emails to avoid sending them to users who already own the single resource being offered in the email. I don't mind - and in fact appreciate - the two to four or five emails I get from Logos every day, because I manage my Logos library intensely. But when I get emails that offer only resources all of which I already own, that just takes my time to look up the resources in my library and see that I already own them. The Daily Deal emails should be easy for Logos to check for this. No good will is generated by sending these emails to users who already own the resource being pitched. Better for Logos and users not to send such emails in the first place.
