What is pop in email
In the context of email, "POP" stands for Post Office Protocol. It's a protocol used to retrieve email messages from a remote email server to a local email client, such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail.
Here's how it works:
- Your email client (e.g., Outlook) connects to your email provider's POP server using your email address and password.
- The POP server authenticates your credentials and sends a list of available email messages to your client.
- Your client downloads the email messages from the POP server to your local device.
- The email messages are then stored on your device, and the POP server marks them as "deleted" or "downloaded" to prevent them from being retrieved again.
POP is a simple and widely supported protocol, but it has some limitations:
- It only allows you to download email messages from the server, not send them.
- Once you download an email message using POP, it's removed from the server, so you won't be able to access it from another device or location.
- POP doesn't support advanced features like email filtering, spam filtering, or email forwarding.
In contrast, IMAP (Internet Message Access Protocol) is another popular email protocol that allows you to access and manage your email messages on the server, rather than downloading them to your local device. IMAP is often preferred by users who need to access their email from multiple devices or locations.
It's worth noting that many email providers, including Gmail, Yahoo, and Outlook, offer both POP and IMAP access to their email services. You can choose the protocol that best suits your needs and preferences.
