I don't know what tier was the problem but I am pledged at Count plus additional contribution and still have not received the email. Friends who are Count indicated on discord last night that they received their codes yesterday. I don't know if they pledged additional funds.
I'm using gmail. Other non-Counts I know who use gmail received theirs.
Nothing still in any junk or spam or other folders.
As of this post it has been 90 minutes since the OP. I'll assume they are still rolling things out but some clarification of the "tier" that is at issue would be nice. I'm not saying I don't trust you but there seems to be some inconsistency in that statement.
