Why are my saved emails being deleted

[Android Central Question]

My phone is a samsung j8Can anyone tell me why my phone deletes my emails after i put them into a folder and return some time later to retrieve them. i.e. i have a travel plans folder. I put my e ticket email in there and later when i go into that folder to retrieve it , it is there momentarily but then a blue line travels across the screen and boom!. It is deleted.

Welcome to Android Central! Which email app, and which email provider are you using? Do you know if you're using the IMAP or POP3 server?
