Samsung Galaxy Core Prime - emails from youtube will not open

[AC Question]

I have a Samsung Galaxy Core Prime Android phone, version 5.1.1 (not a rooted phone) and I am using the email app that came with the phone. Emails from youtube will not open (they are from a channel that I have subscribed to). They used to, but now it just loads for a few seconds, and then it shows up blank. All my other emails open fine, I have no problems with syncing or receiving emails. If I log in to my email on my computer, I can open these emails just fine. Whycan't my email app open these emails any more?
