To start a new message, click Compose
. A New Message window will open and your cursor will be active in the To box. Type the email address of the person you wish to send the email. As you type, contacts that match will display, and you can add them by clicking on their name.
To spell-check your Gmail messages, click the down-arrow at the bottom right corner of the message box and click Check Spelling. Gmail will highlight any misspelled or unknown words in your message.

Gmail automatically saves your messages as drafts as you write them. You can begin a message and come back to it later. You’ll find all drafts in the Drafts folder. You can view your drafts by clicking on Drafts in the left-hand label list.
After you read a message, you can write back to the sender (Reply). If the message was sent to two or more recipients, you can send your response to everyone who was in the original list of recipients (Reply all). You can also forward the message to someone not in the original recipient list (Forward).

When reading a message, click Reply
to write a response to the sender. There are also Reply, Reply all (if the email was sent to more than just you), and Forward buttons at the bottom of the email.
Sometimes you will see three Quick reply choices. Click one of these and Google will load up the phrase you clicked at the top of a reply email. Add more text, attach a picture, or just click Send.

Note: There are many horror stories about email replies that went to all when the message was really meant to go to the sender only. Gmail’s default reply behavior is Reply, not Reply all, but it is possible to choose Reply all accidentally. Be cautious.
One reason email is so popular is the ability to send attachments like pictures and documents with your email.

You can send pictures, videos, and documents in your email, as long as they are smaller than 25 MB in size, combined. Click
, find the file on your computer, then click Open.
You can also drag files from Windows File Explorer directly onto the email. Drag the file from Explorer to the email and drop it.

Large files can pose problems when sent via email. Gmail has a file size limitation of 25 MB (megabytes). That’s adequate for most files. However, you may encounter issues when:
Gmail will display a warning when your message exceeds its limits.

If your file exceeds the limit, you must use Google Drive. Google will automatically save the file to Drive and include a link in the email, instead of bundling the file with the email. Anyone with the link will be able to view, download, and save the files you share.
You can choose to schedule the time the email is sent. Click the down arrow next to Send, click Schedule send, then pick a day and time.

Confidential mode means recipients will not have the option to forward email contents, copy/paste, download, nor print. You must set an expiration date after which the message will no longer be available to the recipient. You can direct Gmail to require a passcode to view the email sent to the recipient via text message.
To start Confidential mode, click
at the bottom of the draft email.
Your sent messages are in the Sent Mail folder. You can find Sent Mail in the left-hand list of labels.
