email from Brother always goes to Spam. How to whitelist?

@wishthiswaseasyno thank you for confirming you don't have any spam filters set up. Is the email address in question set up in your email address book: https://www.xfinity.com/support/articles/delete-contact-universal-address-book

We also have safe connect list you can update emails to: https://www.xfinity.com/support/articles/xfinity-connect-safe-list

I found another post that mentioned similar issues of emails going to spam folders unintentially and here were some steps outlined to fix: 

1. Review spam settings in Xfinity webmail under Settings > Email > Advanced Settings.
2. Mark legitimate emails in the Spam folder as “Not Spam”.
3. Add the email and your own email address to the Safe Senders list.
4. Double-check that both email addresses are correctly saved in your address book.
5. Change your Xfinity email password and review recent login activity.
