iPad Deleting E-mails

[hmlevine01]

When deleting e-mails from either a IPhone, IPad, IMac how do you set it up so that it deletes the e-mails from the remaining other 2 products . Tired of deleting my e-mails on my IPad and then having to delete these same e-mails on my IPhone, then going on my IMac days later and there could be 300 same e-mails waiting that I have to delete also. I have an att.com, and g-mail account.
Thanks Hal

Make sure they are set up as IMAP accounts (or Exchange if that’s what you’ve got) rather than POP.

Both IMAP and exchange accounts synchronise with the web and then across all devices.
