Email – everything you need to know

How Does Email Work? Everything You Need to Know

Email has become such an integral part of our lives that we often take it for granted. But have you ever paused to ask: How does email actually work? Whether you’re managing inbox storage, dealing with junk emails, or trying to set up an out-of-office reply, knowing the basics of email functionality can make a world of difference. In this guide, we’ll explain the essentials of email—how to send a message in an email, keep your mailbox running smoothly, and more.


How Does Email Actually Work?

Email is like sending a digital letter, but faster and more secure. Here’s a quick breakdown of how email works:

  1. The Sender’s Side
    When you send an email, it starts from your email client (like Gmail, Outlook, or another app). Your typed message gets packaged with the recipient’s email address, subject line, and any attachments.
  2. The Journey Through Servers
    Your email client sends the message to a server—this acts as a digital post office. From there, it’s routed through the internet to the recipient’s email server.
  3. Delivery to the Inbox
    Once the recipient’s server accepts the email, it delivers the message to their inbox, where they can read it. If anything goes wrong, like a mistyped email address, you’ll get a “bounce-back” notification.

Emails are fast, but managing them can be tricky. Let’s explore some common challenges and solutions to keep your email running smoothly.


How Does Email Work – How Do I Send an Email?

Sending an email is simple, but if you’re new to it, here’s a step-by-step guide.

1. Open Your Email Client

Whether you’re using Gmail, Outlook, or another platform, log in with your email credentials.

2. Start a New Message

Look for the Compose or New Email button. This opens a blank message form.

3. Fill in the Details

  • Recipient: Enter the email address of the person you want to contact in the “To” field.
  • Subject: Add a brief description of your email’s purpose.
  • Message: Type your message in the body of the email.

4. Add Attachments (Optional)

Click the paperclip or attachment icon to upload files, like documents or images.

5. Send It Off

When you’re done, click the Send button. Congratulations—you’ve just sent your message!

Managing Email Storage

How Do I Keep My Mailbox from Filling Up?

Running out of email storage can disrupt sending and receiving messages. Here’s how to manage it effectively.

Check Your Storage Usage

  • Google Workspace Users: Scroll to the bottom left of your inbox to see your storage usage.
  • Microsoft Outlook Users: Go to Settings > Mailbox Usage to find this information.

Declutter Your Inbox

Delete junk and empty the trash regularly. Sort messages by size to identify space hogs. Before removing attachments, save important files to a secure location.

Avoid DIY Archiving

Archiving emails manually can cause syncing issues. Instead, ask your IT team to set up a secondary mailbox for older messages.

How to Spot and Manage Junk Email

What Should I Do About Junk Emails?

Junk emails are not only annoying but can also pose security risks. Here’s how to identify and manage them effectively:

Mark Messages as Junk or Not Junk

  • Google Workspace: Open the message and click Not Spam to move it to your inbox.
  • Outlook: Right-click the email and choose Mark as Junk or Not Junk.
  • Mac Mail: Use the Junk or Not Junk buttons in the toolbar.

Troubleshooting Junk Email Issues

If important messages are being marked as junk:

  1. Regularly check your junk folder.
  2. Add legitimate senders to your contacts.
  3. Work with the sender to fix security issues on their end.

  3. Save changes to activate.
