Junk mail that is not junk

Use a desktop to do the following:

You can create a filter that will mark those messages as "never send to spam."  To do this, click on the gear icon , select "settings", and under the "filters" tab, scroll down until you see the "Create a new filter" link at the bottom of the page.  Click on it and enter the source and/or content of your emails you want to filter such the sender's address, keywords,..etc.  Click on "create filter" with this search on the bottom right corner and then you can set the filters to automatically "never send to spam."

Also, consider adding those addresses to your contacts if you haven't done that already.  It might help recognize those emails as not spam.

You can also repeatedly mark those emails as "not spam" which might teach Gmail's internal spam filters to regard future similar emails as legitimate.  Hope it helps.

Best,
