Although Internet technology and services have advanced rapidly over the years, a simple email message is still a quick, easy and efficient way to share information with others. If you have a Yahoo account, for instance, you can share an interesting video you produced or discovered on the Web with friends or colleagues by including it an email message. You can send a video up to 25MB in size as an email attachment, or you can send its Web link or URL if it is posted on a website.
Send Video As Email Attachment
Log in to your Yahoo! Mail account.
Select the "New" button to compose a new message.
Click the "Attach Files" button.
Click the first "Choose File" button to launch your system's file manager. Select the video file that you want to attach and then click "Open." You can send several videos at a time, but the total size of the video files is limited to 25MB.
Click the "Attach Files" button. The video file is embedded in your message when you send it.
