Everything You Need to Know About Push Email
Email has been around for decades, yet it continues to evolve. One of the most impactful developments in modern email communication is push email. If you’ve ever received an email instantly on your phone without refreshing your inbox, you’ve already experienced it.
In this in-depth guide, we’ll break down everything you need to know about push email—from how it works and why it matters, to real-world use cases, benefits, challenges, and best practices. Whether you’re a business owner, marketer, or just curious about how email technology works behind the scenes, this article will give you a clear and practical understanding.
Push Email
Push email is a method of email delivery where messages are automatically sent from the mail server to your device the moment they arrive. Unlike traditional email systems that require manual refreshing or scheduled checks, push email ensures near-instant delivery.
This technology has become a standard expectation in today’s always-connected world. From personal communication to enterprise-level email marketing, push email plays a vital role in speed, efficiency, and user experience.
What Is Push Email?
At its core, push email is a real-time email delivery system. Instead of your email client repeatedly asking the server, “Do I have new mail?”, the server proactively sends the message to your device as soon as it’s received.
Push Email vs Pull Email
To understand push email better, it helps to compare it with pull email:
- Pull Email: The email client checks the server at fixed intervals (e.g., every 15 minutes).
- Push Email: The server instantly delivers the email to the client without waiting for a request.
This fundamental difference is why push email feels faster and more seamless.
How Push Email Works
Push email relies on persistent connections between the email server and the client device.
The Basic Process
- An email arrives at the mail server.
- The server detects the new message.
- The server pushes the email instantly to the connected device.
- The user receives a notification in real time.
Technologies Behind Push Email
Several protocols and technologies enable push email, including:
- IMAP IDLE: Keeps a constant connection open for instant updates.
- Exchange ActiveSync: Common in enterprise environments.
- Proprietary Push Services: Used by platforms like Apple Push Notification Service (APNs).
