How to I save grep regex matched result to a variable?

I have a variable : email="[email protected]" and I want to get its username portion to be stored in another variable.

I used the following grep command:

$ $email | grep '.*@'

Which gave me following output.

yask123@gmail.com

I want to save the matched string in a variable.

I tried 

res=`echo $email | grep '.*@'`

which didn't work.

Just in case you want to do something more complex than shell match, which is absolutely valid applied to your example:

res=$(echo $email | sed 's/\(.*\)@.*/\1/')

Try this:

email="[email protected]"
echo "${email%@*}"

Output:

yask123
