How do I stop my Asus tablet automatically downloading my emails in Yahoo mail when i boot up?

[AC Question]

I want to control when I download emails into my tablet - not when I boot it up. I mainly read/use my desktop PC but its useful to be able to access my emails through the tablet but when I want to.

Welcome to Android Central! Are you using the stock Email app, or the Yahoo Mail app? If you use the Email app, and you're using the Yahoo POP3 server, then it will download the emails to the tablet. If you use the IMAP server, it doesn't download anything--it essentially syncs with the server. So either use the IMAP server for Yahoo (https://help.yahoo.com/kb/SLN4075.html) or use the Yahoo Mail app, which doesn't download emails locally.
