• Use labels to organize your emails. 

Labels are like folders, but you can apply multiple labels to a single email. This allows you to create a more granular system for organizing your emails.

• Use filters to automatically sort your emails. 

Filters can be used to automatically sort your emails into different folders or labels. This can save you a lot of time, especially if you receive a lot of emails.

• Use templates for frequently sent emails.

If you find yourself sending the same types of emails over and over again, you can create templates to save time. To create a template, click the More options button (three dots) in the bottom right corner of the compose window and select Save draft as template. You need to enable it in settings.

• Use the search bar to quickly find emails.

Gmail has a powerful search bar that you can use to quickly find emails by sender, recipient, subject, keyword, and more. You can also use advanced search operators to narrow down your search results.

• Use snooze to postpone emails. 

If you receive an email that you don't have time to deal with right away, you can snooze it until later. To snooze an email, click the Snooze button in the top toolbar and select a date and time.

• Use undo send to cancel a sent email. 

If you accidentally send an email, you can undo it within 30 seconds. To undo send, click the Undo button in the bottom left corner of the screen.

• Use attachments to share files.

You can attach files to emails to share them with others. Gmail supports a variety of file types, including documents, images, and videos.
