POP3: POP stands for Post Office Protocol. Using a POP3 account you log into your email server using a local email client.  Your email is downloaded from the server to your computer. The email is removed from the server and transferred to your computer.

There are advantages and disadvantages to using a POP3 account.

One of the advantages of POP3 is that if your internet connection is down you will still be able to view the messages that were downloaded prior to your internet service being disconnected. A disadvantage of using POP3 is that you will not have access to your email from another location or device such as another computer, laptop, smart phone or tablet. Although many email clients do have an option to “leave a copy of messages on the server”

POP3 is becoming outdated. Today most users access their email from different locations and devices, for example their computer, tablet and smart phone. When using more than one device to access email IMAP is the preferred choice. 

IMAP: IMAP stands for Internet Mail Access Protocol. Using an IMAP account setup in a local client you can view your messages in the local client but the email is stored on the server. Unlike POP3 your email is not download to your computer and removed from the server. The advantage of using an IMAP account is that you can access your email from other locations and devices since the messages are never removed from the server. IMAP allows you to login to your account using many different local clients, web based email or using a smart phone or table.  

Email Clients and Webmail: Gmail, Outlook.com and Yahoo Mail are all examples of webmail. Microsoft Outlook, Microsoft Windows Live Mail and Thunderbird are examples of an email client.

When you use an email client you install a program locally on your computer. You setup a mail account in that program. Some providers support both POP3 and IMAP, some don’t.

Using webmail you do not install a program on your computer. You access your email through a web browser. All of your email is stored on the server. Nothing is downloaded to your computer. You can log into your email account on any computer or device with internet access.
