echo "send summary to Tim today" | mail firstname.lastname@example.org
It sends mail at (in this case) 4:27 a.m. on the next Tuesday. The mail says:
"send summary to Tim today."
To send more than one line, you can use a temporary file:
...put message body in msgfile
at 0808 feb 28
mail email@example.com < msgfile

every hour, or whatever: use the commands in items 1 or 2 above.
