3: Attach files to email
You can attach up to 25 MB of files to a message in Gmail. To attach a file, click at the bottom left of the message window, then select a file. If you attach multiple files to a message, they can't add up to more than 25 MB.
If you have files that are larger than 25 MB, you can send them as Google Drive attachments.
