Interesting point about charging for unsubscribed contacts! I am building an Open Source email marketing platform (https://www.keila.io https://www.keila.io) and our current pricing model only considers the amount of emails you send, not the number of contacts/subscribers. I've been thinking about switching to charging per contacts instead – and I probably wouldn't have considered not including unsubscribed contacts if they're still stored on the platform. But now I will, thanks!
