I received one newsletter e-mail from them so far, but that is pure marketing. Self advertising. They are writing about ***"all the cool things happening over the last year and more good things to come."***
But that may be good to reach out to the inactive users, and if they return and be active in the long term, then the activity and the interest in Steem will increase, which may lead to relisting (or listing) Steem on exchanges. We will see.
