Q: icloud site keeps shutting down when writing a new email

Hi mtclark007,

Welcome to the Support Communities!

The first thing to check is the System Status at the iCloud Support web site (see link below).   It's possible the Mail servers may have been experiencing an issue during the time you were typing your email.  The links below will provide some additional iCloud troubleshooting information:

Apple - Support - System Status
