'not junk' action/function

[mattw-webcv]

Hello,
I'm not on reddit or any other kind of social media so I can't/wont participate there.

I've been getting legitimate email sent to my junk folder.
I'd like a button to mark emails as not junk so this no longer happens.

The only possible fix I've thought of is to create inbox rules, however this has failed.

Some examples of legitimate email senders I deal with are:

Nautilus newsletters
newsletters@nautil.us

The Guardian
info@editorial.theguardian.com

Australia post notifications
noreply@notifications.auspost.com.au
