Invite your friends to Gmail - send 25 MB's of attachment

Now you can send bigger attachments in Gmail, as Google increased the maximum attachment size from 20 MB to 25 MB.

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," suggests Google.
