Let alone that matches don't get executed by grep.

To execute the output of grep, you need to {mis,}use a workaround such
as

[rocketmouse at archlinux ~]$ $(echo "foo at domain.com; rm -i /tmp/*; bar at domain.com; Lorem ipsum" |grep -o '[a-zA-Z0-9]*@domain.com')
bash: foo at domain.com: command not found
