Not getting e-mails

I started to check my email a couple of nights ago. It said I had 36 emails. I opened it up. It came up on my phone, then the screen went white, with a paper airplane pic, and said no emails. They were there for about 5-10 seconds then the screen went white before I could even open my first email.
Can you tell me what happened? I haven't gotten any email since that happened, when as a rule, I get between 30-50 emails a day. I'm upset and would like to know what's going on. I belong to some groups, and missed out on several give a ways that were going on.
Please advise what's going on.
