notification email

Hello, Is there a way to add some customization to the email that comes from eSign live to notify people that they need to sign a package? These signers are using our application which generates these packages automatically, and we're concerned that they may not recognize the email from eSignLive. Ideally we'd like to do things like add our own logo to the email, and maybe change the text. If that's not an option, can the email be simply disabled so we can send our own custom email? Thanks, Dan
