Hi colleagues,

I'm required to do sentiment analysis on email communication and as the data is unlabeled, I was wondering if someone knows about a public dataset I can train a custom model on. I'm aware of several twitter/movies datasets and other of that nature however, I'm looking more for something closer to email communication between customers from tech companies and their support/sales teams. That would be my domain.

Also aware of tools like Google NL API and Amazon Comprehend but trying to avoid charges.
