SQL, null in where clause

Hi Expert,

I want to know the count(*) when alternativedeal = 'Null'. But my query returns 0, it should be give me the result of 'Number 30. How could I fix it? Thanks.

count (*)
from MMD_Feed..Deal
where dealerid=99
and cast(submittedtimestamp as date) between '2015-04-01' and '2015-04-30'
and alternativedeal = 'Null'

btw, a better way to deal with this that does not require CASTing every value...
and (submittedtimestamp >= '2015-04-01' and submittedtimestamp < '2015-05-01')
