Gmail debuted on April Fool’s Day 20 years ago. Yet, impressively most people have never heard of these useful hacks.

Here's how to undo it:

6. Use Gmail with keyboard shortcuts

Enable shortcuts:

• Click on the gear icon or "Quick Settings" (top right).
• Click on "See all settings".
• Toggle on "Keyboard shortcuts" and "Save changes".

Here are some of my favorites:

• Select a message, then Shift + I to mark as read, Shift + U to mark as unread.
• ⌘ or Ctrl + Enter to send an email
• ⌘ or Ctrl + L to insert a link
• C to compose
• D to compose in a new tab
• / to search your emails
• Shift + Ctrl + B to add BCC recipients

7. Snooze an email

Have an email you don't want to deal with immediately?
Set a reminder for later

• On the list of all emails received, click on the clock icon on the right.
• Choose how long you want to snooze the email.
• It'll appear back in your inbox on that date and time.

8. Use labels

Labels can help you organize your emails more effectively.
Create custom labels for different types of emails, such as "Work", "Personal" or "Travel"

• Simply click on the "Labels" button in the toolbar and select the label you want to use.

9. Create templates

Speed the process of creating customized emails templates.
First enable the Templates feature:

• Click on the gear icon or "Quick Settings" (top right).
• Click on "See all settings".
• Select "Advanced" in the top bar, then enable "Templates" and "Save changes".

Now create your template:

• Select "Compose" to start a new email message.
• Enter the text you want to use for your template in the email field.
• Select the three-dot menu and then "Templates".
• Select "Save draft as template" or insert an existing template.

Lastly, archive important emails (don't delete them!)

Archive messages, or set up filters to automatically move messages to the archive. No need to schedule rules to run at regular intervals. After you archive messages, you can still find them under the label "All Mail".
