HELP!

So… I set up my kindle with my husband and my Amazon account. I did not take into consideration that it’s HIS email that it’s attached to…

He gets an email every time I finish a book!!!! He has stopped reading the descriptions of the books lol. He can still see the title in the email though and so I’m deterred from reading some books because of the title 😭

I am thoroughly embarrassed and mortified. Someone tell me there is a way to fix this. How do I stop the emails 😭
