What is an Email Client?
Email client is a software application that enables configuring one or more email addresses to receive, read, compose, and send emails from that email address(s). It also provides a central interface for receiving, composing, and sending emails to the configured email address(s).
How Does Email Client Work?
When a sender sends an email to anyone, the email is first sent to a mail server like SMTP. Then, the mail server contacts DNS (Domain Name System) to locate the IP address of the recipient. Once the IP address is located, it checks if the recipient domain has any mail exchange server or not. Then, the message is sent to the email recipient’s MTA server. The MTA server then decides where to put the email and sends it to the recipient, and the recipient gets the message.
How to Choose the Best Email Program?
Here are some important features that must be included in any best email clients:
- It should allow you to send unlimited messages to anyone.
- It can manage multiple email accounts by combining archive, inbox, or sent folder.
- An email client must comply with the protocols IMAP, POP3, etc.
- It should allow you to access calendars and plan events.
- It should allow features like undo send, restore email as well as scheduled delivery.
Does Windows 10 have a Default Email Program?
Yes, Windows 10 has its default email program called Mail App. However, you can change the default email program as you want. For example, you can set Outlook as your default email program in Windows 10.
What is IMAP, POP3, SMTP?
IMAP: IMAP, or Internet Message Access Protocol, is a mail protocol used to access email on the webserver from the local PC. It stores messages on a server and synchronizes them across multiple devices.
POP3: POP3, or Post Office Protocol, is a mail protocol used to receive emails from the server to the local email client. It allows operations like downloading email messages on your computer and deleting them from the server.
SMTP: SMTP or Simple Mail Transfer Protocol is an application layer to send messages to the mail server for relaying.
When you send emails, the web server processes them and decides which server to send messages to. The mail service provider downloads the emails and places them in the recipient’s inbox.
