This problem is not resolved, I’ve same problem and cann’t login to my Netdata cloud account because don’t get any email delivered.
As above, send your email address to chris@netdata.cloud, so I can look you up in the deferred or blocked recipients.
I also have the same problem – I have been using netdata for a couple of years with no problems, but now no longer receive the emails. I have access to our spam filter system and can see that the mail is not even arriving there.
