Oh BTW, I was asked about this by Reynold. Few month ago and I said the similar answer.

I think I am not supposed to don't recieve the emails (not sure but I have not recieved) so I am not too sure if this has happened so far or occationally.

In the case of my accounts, I manually went to https://ci.appveyor.com/notifications and configured them all as  "Do not send" and it does not send me any email.

However, in case of AFS account, this turns out an assumption because I don't know how it is defined as I can't access.

This might be defined in account - https://ci.appveyor.com/notifications
or in project - https://ci.appveyor.com/project/ApacheSoftwareFoundation/spark/settings

I'd like to note that I disabled the notification in the appveyor.yml but it seems the configurations are merged in Web UI, 
according to the documentation (https://www.appveyor.com/docs/notifications/#global-email-notifications).

Should we maybe an INFRA JIRA to check and ask this?

I'm not sure why the AppVeyor updates are coming to the dev list.  Hyukjin -- Do you know if we made any recent changes that might have caused this ?
