We do not email players unsolicited, we only reply to support tickets. We may consider a mailing list for those that wish to be notified by us, but a core value of SwC Poker is to respect player privacy.
We have been running the 3.0 platform for about a week. The focus is on security and fixing bugs. The beta team continues to test the next update of SwC Poker, which is likely to be released next week. More tournament modes will be introduced in that update. The tournament schedule is being reviewed after receiving input from the community.

If you comply with CAN SPAM rules (first link), then
"Bulk Email is normal email
(examples: subscriber newsletters, customer communications, discussion lists)"
as defined in second link.
I'd suggest you to read more about this and reconsider the definition of "unsolicited emails". With all due respect to privacy.
Regarding tournaments, I'd suggest to open as many as you can, of all sorts. After a while, should be easy to decide which are played more and worth improving and which ones should be killed without regret, because aren't played. Voila, listening to customers.
