Difference Between POP & IMAP
POP (Post Office Protocol)
POP3 allows you to download copies of your email messages to your personal computer. Here the difference between POP & IMAP . Any changes you make will NOT be visible to other users or computers accessing the email account. This is because you are only making changes to local copies. Consequently, you can only view the messages sent from a computer using POP on that individual computer’s folders.
The copies of the email messages on the server are normally unchanged. But it is very easy to unintentionally configure your POP3 program to delete those server copies whenever you download the emails or at a future time.
We recommend POP for:
- Users prefer to keep a backup of all their messages and have very limited time to be online but need to read emails.
- Users need to archive permanent copies of their emails. (e.g. before you terminate that email name or its hosting provider).
IMAP (Internet Message Access Protocol)
IMAP4 allows you to read emails as they appear on the hosting server. All messages and any changes you make (delete, reply, forward, move) are seen by anyone else as well as who logs into webmail or IMAP. Depending on program configuration, you can temporarily save the messages for offline viewing.
We recommend IMAP for:
- Users who connect to email accounts from many computers and users with mobile devices with internet access, such as smart phones or tablets.
- Multiple users who need to access the same email account and wish to always have their messages, including sent messages and message folders, saved on the server.
Accessing Email: Difference Between Email Programs & Webmail
Email Programs
An email program can be launched right from your desktop and provides you rapid access to all your emails. They also have advanced tools and features which webmail may not have.
While email access through an email program is speedy, it can be less secure than webmail if you let the program remember your password.
There are many programs to choose from, including the program included with your computer’s operating system.
Microsoft Windows includes either Outlook or Windows Mail and Apple includes Mail. There are also third-party programs such as Mozilla’s Thunderbird and Qualcomm’s Eudora.
Webmail
Webmail is often preferred due to its ease of use and the fact that it can be accessed from any computer through a web browser. Plus, it has the same advantages as IMAP.
However, webmail depends on a web browser (e.g. Firefox, IE, Opera, Chrome, Safari, etc.) which can take some time to load, access the webmail page, login and load the GUI. Also, webmail often displays a limited view of the inbox, allowing the user to view only one email message at a time.
Conclusion
IMAP is perfect for multiple users who need to access the same email account or one user who needs to access emails from multiple locations.
POP3 is perfect for quickly downloading emails and reading them offline or on the go (though you do have to be online to reply to emails). POP3 is also a great way to save copies of your emails on your personal computer.
Webmail is perfect for everyone, but does depend on a browser which can sometimes be slower and more cumbersome than a mail program.
