Since yesterday, I have been wondering what this email was meant for. At the moment, there are no specific infos, apart from emphasizing that the old price can be kept (lower by implication). A few ideas have already fallen.
This thought came to me after reading this https://discussion.evernote.com/forums/topic/131224-to-all-disappointed-premium-users-lets-cancel-our-subscriptions/?tab=comments#comment-590743
Is this email from EN that only mentions prices not a threat? If users now cancel their subscription and want to renew it, they will pay the new higher price.
I am beginning to wonder if this is blackmail and an attempt to stop mass cancellation of subscription, after all, you can always renew them before the end. And now many people are wondering, I will cancel the subscription now and I don't know how much I will raise, so maybe I'll wait. Fear management, effective but only in a dictatorship.
If they gave details of their plans (EN roadmap), and not only information about the price, I would be far from making such guesses.
