Does deleting emails from an ipad automatically deletes them from your iphone?
 

I want to delete all my emails from my ipad, but, don't want to delete many of them from my iphone.

Are the two connected? So if I delete them from my ipad will they automatically delete them from my iphone (which I do not want)??

If you delete an email from an Outlook, Gmail, Yahoo, etc., account, it's deleted. A device is just a way to look at a specific email in a specific account.

Unless you've done something funky, like downloaded then stopped refreshing on one device, yes, all devices should show the same email content.

In the past, one had the option of using POP3 or IMAP to connect to mail servers and download mail. POP3 tended to keep emails on the server unless your mail client was set to specifically delete emails after downloading.

These days, though, POP3 isn't used all that much (AFAIK). Assuming you're using a common mail service like one of the ones CPRich mentioned, I wouldn't worry about it. And even if you aren't, there's likely not much of a need to worry about emails not disappearing from all devices when deleted.

Probably the easiest option. My guess here is that your iPad is running out of room and you want to clear space but don't want the emails deleted?
