I want the ability to send an email to an iOS users iPad's POP account and have them instantly recieve a notification.
For example, on my Android devices, since gmail is built into the system, if anyone emails my gmail address, I get a notification about 1 second after they hit send on their end. If its a pop account, then I have to wait until the next pull, every 15, 30, etc minutes (whatever the user has it set to).
Can iOS receive the gmail type instant notifications? And if so, how does the email account or notifications settings need to be set up?
