Learn the Difference Between POP and IMAP

The big difference between POP and IMAP two is that with POP all email is downloaded from the mail server and with IMAP the mail remains on the server.

Which protocol you prefer is entirely up to you after learning the exact difference between pop and imap. If you want to be able to read your email at multiple locations, keep your email safe or save disk space on your hard drive, then the best option is IMAP. However, if you would like to archive all email yourself, save disk space on your web server, or if you do not have a constant connection to the internet, then POP is often a better choice.

Discussing the imap and pop difference here can let you understand how both work.

POP: Post Office Protocol

With Post Office Protocol POP you can retrieve emails, just as you would (very) formerly collect mail from a post office. You state who you are, the employee checks whether there is new mail for you and gives it. Your mail program does the same with POP: it connects to the server, says for whom it is coming to collect the mail, and the server passes on the new messages. Your mail program downloads these to your computer for you to read. The messages will then be on your computer and no longer on the pop server.

IMAP: Internet Message Access Protocol

The Internet Message Access Protocol is very suitable for handling email from different computers. For example, at home, at work, and while traveling. The contents of the mailbox are exactly the same on every computer. All incoming, read, and sent e-mails can be viewed anywhere, anytime because they remain stored at XS4ALL. Another advantage of IMAP is that if your hard disk or computer breaks, your email is still safe on its Imap server.

With IMAP, your mail program still connects to the server, says for whom it wants to retrieve the mail, but then only retrieves the address data of the mail (instead of the entire message). These address details tell:

  • to whom the email is addressed
  • who the sender is
  • at what time it is sent
  • the size of the message.

Compare it with an extensive address sticker on a parcel.

Only when you click on the message will the complete message be retrieved from the server. At the same time, the message also remains on the server. In fact, IMAP makes a copy of the message on the server and keeps this copy on your computer. In addition, your mail program keeps the connection with the server open so that you see new emails coming in immediately.

What is IMAP and POP in email?

The imap is used for accessing email from any device or from anywhere. You are not storing or downloading an email on your computer when you read the email using IMAP. As you are reading it from the email service. So that you can check your email from your phone, a friend’s system, or a computer.

You can only download the email message using IMAP when you click on it. However, you cannot download attachments automatically. The main pop imap difference is that you can check messages faster than POP using imap.

Alternatively, you can contact your email service and download all the new messages using pop. The messages will be deleted after you download them from the email service. You can only access them through the same computer because trying to access your email from a different device makes your messages unavailable.

Which is safer IMAP or POP?

According to data safety, IMAP is much safer than POP. This is because it keeps all emails on the server. It means that if your device gets stolen or lost, the emails present in it will still be secure. On the other side, pop stores emails on the local device. You will lose all your emails if your device is stolen or lost.
