How can I avoid receiving Flipboard emails/notifications I have a Samsung Galaxy S6 with Nougat.

I keep on receiving emails/notifications from Flipboard. They don't use my old registration email address but MY GOOGLE ACCOUNT ADDRESS.

I checked in settings but I didn't find nothing that I can do. Hence,the only way to avoid receiving emails is to delete the account? Or,are there other ways?

Update:

I DIDN'T CREATE A FLIPBOARD ACCOUNT WITH GOOGLE ACCOUNT EMAIL ADDRESS AND PASSWORD.
Now I deleted this account but it's still working.Need I to wait?  
Can,please,someone suggest to me if it's better to delete the old account too?and change,I know it's not so easy, email address and password of my Google account?
The question,now,is who has made the "Google account"and where have they found my Google credentials?

Thank you
To stop receiving emails from Flipboard, simply unsubscribe from their email list. You can usually find an unsubscribe link at the bottom of the email. 

If you can't find the link, use this page to unsubscribe.

To stop receiving notifications from the app, go to your phone settings -> application Manager -> Flipboard -> notifications, and switch "allow notifications" to "off"
