Types of Email Accounts

If you thought an email service was just an email service, I’m afraid you would be wrong. There are actually two main types of email accounts you can choose from; an email client like Outlook, or webmail like Gmail.

Before finding out which free email service is the best for 2021, let’s explore the different types of email accounts you can choose from, as well as the main email protocols (POP3, IMAP, and Exchange).

Email Clients

You can think of an email client like a software application. You’ll need to physically install an email client onto your computer in order to send, receive, and manage your emails. Email clients interact with a remote email server so that you can access your emails. Familiar email clients include:

  • Microsoft Outlook
  • Mozilla Thunderbird
  • Apple Mail
You can still access email clients via the internet, for example if you go to outlook.com. This will require a specific email protocol which we will discuss below.

Webmail

Webmail can be accessed from the internet and exists on the cloud rather than your computer or laptop. Unlike an email client which needs to be downloaded on your computer, you can send and receive your emails from your internet browser. Familiar webmail providers include:

  • Gmail
  • Yahoo! Mail
  • AOL
Many webmail providers also offer mobile apps, so you can access your emails from your mobile device. Your webmail provider will use one of the email protocols outlined below.

Email Protocols

Email protocols are a standard method used at each end of a communication channel like email. They are used to retrieve email client accounts from the internet and access webmail accounts on mobile. There are three main types of email protocols; POP3, IMAP, and Exchange.

POP3

Post Office Protocol (POP) is suitable for individuals who have one email account and email client. POP3 is the most recent version of POP, allowing you to access your emails even when offline. POP3 requires less internet bandwidth and is a client/server protocol where emails received are held by your internet server so you can retrieve them.

IMAP

Internet Mail Access Protocol (IMAP) allows you to access, retrieve, and manage your emails while online. Unlike POP, you don’t download your emails to an offline email client. IMAP is often used by those who have more than one email account and want to access them from more than one device or location.

Exchange

Exchange is Microsoft’s email protocol. You can access your email from the internet from multiple devices, as well as manage tasks, calendars, and contact information related to your email address. Exchange is often used by businesses who need to share information, create meetings, and so on.
