No. It sounds like a really nice idea but I can't have you e-mailing my customers, that'd just be embarrassing. I would also need to really understand your security posture. I couldn't use it for my app as all its functionality needs to work in an airgapped environment. But in any case, I would consider offering a paid tier where you don't use it to send marketing messages. I also believe that using it in the way you propose could cause you to run foul of GDPR because there isn't a way to separate the marketing message from the app functionality but I don't have a well formed version of that idea yet.
