how do I prevent a sender from going to junk folder

Have just confirmed the following: the action of using Mac Mail to assign a sender to Mac Mail's Junk Folder is correctly translated, via IMAP protocol, to a Gmail account (i.e., logging directly into the Gmail account reflects that same sender residing in Gmail's Spam folder). However, attempting to reassign that sender to be "Not Junk" in Mac Mail DOES NOT translate back to the Gmail account. One is required to log directly into the Gmail account and reassign the desired sender as "Not Spam" in the Gmail Spam folder in order to prevent that sender from showing up in Mac Mail's Junk folder going forward.

Many thanks to Safarionwin for providing the clue to track down the glitch.

Safarionwin,

Thanks much! I think you may have pointed me in the right direction, though through a different destination than the one you called out. I am using the Mac Mail app to process a Gmail account via IMAP protocol. Your iCloud suggestion guided me to Google's Web Mail spam folder where I was able to select the desired emails and toggle "Not Spam," at which point those emails appeared in my inbox within the Mac Mail app. I feel fairly confident this will solve my issue and will report back when confirmed.

Once upon a time, there was a fairly obvious method for marking as 'Not Junk.' It is no longer so obvious. I just now looked high and low and cannot find any option for marking an email as 'Not Junk.' Any insight on where that setting resides in the latest Mail app? Just moving the mail into the inbox doesn't seem to be sticking?

So to be clear, there is no longer a manual 'Not Junk' setting?

Will give your described method a try. I had been manually dragging unopened emails from junk folder to inbox with no apparent success, but lately I had been Control Clicking unopened emails in Junk and selecting "Move to In Box" from the drop-down menu, This probably accomplishes the same thing as what you describe above. I guess I'm still at the mercy of the nebulous "multiple-count" function to do its thing. Sigh…

Thanks for your assistance.

BDAqua,

Followup: It's been nearly a month and numerous instances of my selecting the desired post and clicking Not Junk icon as described above…and still they arrive in the Junk folder. It is not learning as we supposed it would.

Interestingly, I have a tiny x instead of an up-arrow on the normal Junk icon (however, it does change to a down arrow while in the Junk folder).

Good catch, BDAqua!

I just verified that, when you set your custom toolbar to display "Icon and Text" (which mine wasn't) it does indeed change to Not Junk. Interestingly, when you hover over the "Not Junk" icon, the tool hint reads: Move Selected Messages To Inbox.
