how to synch emails across ipad and iphone

That is a syncing problem with the server. If they have a webmail interface see how well that syncs. Do you have any problems sending mail from either device? The syncing function uses the outgoing mail server. But the problem is with the server.

How to sync emails to iPhone and iPad

Connect both to the same e-mail account. You want a type of connection where the master copies of the e-mail remain on the server (e.g., IMAP as opposed to POP).

Add an email account to your iPhone, iPad, or iPod touch - Apple Support

Set up mail, contacts, and calendar accounts on iPad - Apple Support

What is the part of your email address after the @ in your address? For example, @icloud is your Apple hosted address. @gmail is gmail; @yahoo, @aol, etc. If you set up email in Settings/Mail/Accounts you just enter your email address during setup and it will usually set up automagically.

The answer to this depends completely on your email service provider and the type of email (IMAP, POP).

For example, iCloud email would always sync immediately.

Email never syncs device to device; instead, email syncs to your mail provider's server. So if both devices are logged in to the same email provider they will sync automatically.
