There’s nothing all that new here — Apple has long deleted some email messages silently, even including TidBITS at various times — but Dan Moren and Lex Friedman show how iCloud can delete messages containing certain phrases with no warning to the user, even if the phrase occurs only in a zipped PDF attachment. So if something you’re expecting doesn’t show up (assuming you notice), consider asking your correspondent to send it to another email address. follow link
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
Macworld Tracks Down iCloud’s Silent Email Filtering
In my opinion, iCloud email (iCloud in general) has many sub-par features. Reliability alone is poor.
* Rules set in Apple Mail aren't synched with the iCloud site,
* rules aren't even available in the iOS mail app.
* Mail is synced fine on the iOS side, while the desktop periodically fails.
* And now, flaws in the junk filtering algorithm?
Just some examples of the utter confusion and disarray found within the Apple software ecosystem.
If I need to have someone send mail to another address, I may as well not use iCloud for mail at all.
But it's worth remembering that iCloud is not an ISP, so every iCloud user has at least one other email address, whether or not they choose to use it. (Hmm, that may not be strictly true for people who use only an iPhone or iPad, perhaps only on public Wi-Fi. But that's still a small group.)
And with plenty of free email providers like Gmail, Yahoo Mail, and Outlook.com, it's easy to add another address at any time.
As to whether one should trust iCloud for primary email, well, personally, I don't. I use it for testing, and as a secondary address, but I don't feel that email is Apple's priority, and there have been too many problems over the years to make it my primary address.

The cited support article indicates that Gmail may reject incoming messages if they contain "spammy text" or if the sender "has a history of sending unsolicited messages".
