 You can use printf(1) to get newlines in your commands, though you'll
 have to escape the backslash twice:

+*/10 */2 * * * printf '\%s\\n\%s' "hey bob" "it's $(date +\%H:\%M)" | mail -s hey bob
 
 Or if you want to have a special character standing for newline, (e.g.
 @) you can do that with tr, or sed:
 
-*/10 */2 * * * echo "hey bob@it's $(date +%H:%M)@Made With tr(1)" | tr @ \\\\n | mail -s hey bob

 (Note the doubly-escaped backslashes in all of the above!)
