Insert values into a table with multiple select query

Hi,

I have a table called MailTo, Below is the structure of the table.

To the To_mail column i should insert mail ids from a multiple select queries. Below are the two queires where i get two mail IDS and one ID will be hardcoded. 

(select main_usr_email from tbl_main_usrs where main_usr_id_pk = @userid )

(Select  email from v_empSup  where usr_id  = @sessionUserID )

'XJAWebmaster@wabtec.com'

These are the IDS to be inserted into Mailto table . Please help me out with this

Create table Mail
(
Mail_ID          int IDENTITY Primary KEY   ,
USERID           int,
[Type]           varchar(100),
FirstName        varchar(50),
LastName         varchar(50),
