mistyped the recipient email account

I sent an important contract via adobe sign last Friday. The next day I realised that I mystyped the recipient email account. It seems that the first wrong contract email was not open, because according to the 'final audit report', there is no recipient IP address marked. But this is just my judgment and I don't believe it. I'd like to hear from a technical expert. Please answer me asap, I've been worried about my mistake becuase there're so much private informations included.
