Send or save as draft. 25MB is your birth right with gmail. Ya but you can send this fatty size only to gmail accounts.

Google says:

With Gmail, you can send and receive messages up to 25 megabytes (MB) in size.
Please note that you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits. If your attachment bounces, you should invite them to Gmail.
