Android
Android's built-in Gmail client uses Google Cloud Messaging to push email for Gmail accounts set up to sync with the phone. Android also supports Microsoft Exchange accounts natively through its default mail application. When "Push" is configured, emails arriving into the Microsoft Exchange inbox are instantly pushed to the device. Calendar events sync both ways between Exchange and the device.
Yahoo Mail may be pushed to an Android device, as Android now supports IMAP4 (as of September 2015).[4] An alternative for Yahoo Mail is to install the free Yahoo Mail app, which provides instant push email. Numerous Yahoo users have complained that push does not function reliably; Yahoo has attributed this to server issues rather than the Smartphone app.
In 2010 Hotmail, and its replacement, Outlook.com, have been made push configurable for Android smartphones through the default mail application.[5]
Windows Mobile and Windows Phone
Microsoft began offering real-time email notification with
Nokia Symbian Series 60
Some Nokia Symbian S60 models support basic IMAP IDLE functionality with its built-in client. But on newer E72, E52 etc. phones this functionality is broken, because connection to the mail server is closed (probably even outside the mailing application) and never restored.[7]

Nokia Messaging
Nokia Messaging Email is a push email service and client application that supports most of the popular email providers like
Palm OS
Palm Smartphone devices have had IMAP IDLE[12] available through the use of 3rd Party software ChatterEmail as early as 2004. There is no additional server software required.
Palm webOS
The Palm Pre webOS has push email for Gmail, IMAP, and Exchange accounts.
BlackBerry
BlackBerry became very popular, in part because it offers remote users "instant" email; new emails appear on the device as soon as they arrive, without the need for any user intervention. The handheld becomes a mobile, dynamically updating, copy of the user's mailbox. As a result of the success of BlackBerry, other manufacturers have developed push email systems for other handheld devices, such as Symbian- and Windows Mobile-based mobile phones. However, they only support push email for some email services.
With the release of the BlackBerry 10 operating system for its new generation of mobile device, BES is no longer available for non-corporate client email delivery. Instead, BlackBerry 10 offers POP, IMAP, or ActiveSync for transferring email to and from a device. Of these, the latter two can provide push email delivery if the server supports it. Data compression is also not provided anymore.
Sony Ericsson
Sony Ericsson Smartphones (M600, P990, W950, P1, W960, W995, G900, G700) as well as some Cybershot phones (K790, K800, K810, K850, C510, C905, J105i) feature push email using IMAP IDLE or with the built-in ActiveSync client (developed by Dataviz). Most other Sony Ericsson phones support IMAP IDLE push email quite well (only the inbox however).
Other mobile solutions
Most non-proprietary solutions are network independent, meaning that as long as a device is data-enabled and has an email client, it will have the ability to send/receive emails in any country and via any telephone company that has data service on its network. It also means that as long as the device is not SIM locked (in the case of GSM systems), the constraints of BlackBerry, such as network locking, vendor locking (BlackBerry devices and BlackBerry Connect devices) and data-roaming charges (for non-home access) are not an issue. For a GSM system, install a SIM card appropriate for the location, have the correct APN settings and one's mail will be delivered at local rates.
Simulation using traditional email
Traditional mobile mail clients may poll for new mail at frequent intervals, with or without downloading the mail to the client, thus providing a similar user experience as push email.
Protocols
In contrast to traditional[13] email, most of the protocols used in popular current systems are proprietary. For example, BlackBerry uses its own private protocols. Both the Push-IMAP standard and parts of the SyncML standards are attempting to develop more open solutions.
